Installing B&m Shiftplus On 4t40

[Oldsman]

TO INSTALL SHIFT KIT #70380 AT TRANNY: this install was done on a 99 2.4 4speed auto.


It provides the scotch lock and male connectors you need. The switch has the wire attached, so just put that in the interior then run the wire through the gromit in the firewall, you'll see how easy that is.


this connector is found in the front of the transmission to the left of the battery, it is gray and circular, it is 2 inches in diameter. Comes off with a pinch.


the wires u are connecting is the black wire to the light blue with white stripe ( C on the plug), now the red wire you want to install to is the red wire with black stripe( D on the plug) this wire is directly underneath the light blue one, not the one to the left of it, which is another red with black stripe wire, which has a dark blue wire underneath, look at the connector with the white arrow at 9 o'clock. The letters are on the plug right near the wires you need.


settings must be selected while car is off.


On setting 1, i can easily chirp 2nd gear and it shifts firm. I would say ok for everyday driving. This setting reminds me of astandard shift for the older turbo 350 and 400.

On setting 2, I can chirp 2nd and 3rd (i tested it on the way home, marc.) this shifts hard. I would say too hard for everyday driving but good for racing.

[Oldsman]

Oh forgot to to post price...........duh.

I got mine thru jegs.com for $48.00 shipped. I would have to say best $40 i have ever spent.

[bdyman]

sweet it sold me
hey scot will it work on mine??

[Oldsman]

it will work on any 4t40 tranny. which is the auto for the 2.4 and ecotec.

[overdrive75]

Electrically there are no wiring differences between a T40 and a T45 should work on both. I don't recommend it but if you are so inclined to boost line pressure, have at it.

[1WhiteOSV]

anything for the 3400??

[Oldsman]

this will work on both transmissions. 4t40 and 4t45

[AleroSS]

anyone have track times or timeslips on the way with one of these added?

['04 aler-ho]

so does this thing take place of the auto trans interceptor

[bigd6983]

I see that this would fit the 3400, and I know there is one on pfyc.com which one is better, similarities and differences because he said that one was 48 and the one on pfyc is a little over a 100, now they are both adjustable but this one can be adjusted while in the car which I like a little more. Any down falls to doing this in the long end? I dont plan on having it at top notch all the time maybe just every once and a while. let me know people, thanks.

[bigd6983]

well i was impatient and went searching around the web for one because I couldnt find it on jegs, found it for 39 bucks shipped on this website motorpartscentral.com, want to have something to do to it once I get it back from getting the body fixed up, and before I go get it tinted up.

[Oldsman]

there is no track times with the B&M.

The B&M shiftplus does the same thing as the auto interceptor.

the differences is.........

the B&M is not adjustable. You have off, stage1, and stage 2 settings.

The advantage of the B&M is.........

you can turn it off.

With the auto interceptor it is on all the time unless you unplug it from the tranny. With the B&M you just flip the switch to Off.

CHANGING SETTINGS MUST BE DONE WITH CAR TURNED OFF.

[bigd6983]

yea oldsman thats what I meant by adjustable, just worded it wrong, exactly what im looking for though, cant wait to get it in the mail and hook it up. thanks

It says part #70380 is for RWD and 4x4 vehicles only.....

[Oldsman]

You are correct. But it works just fine. J-body guys have been running it for quite awhile. It's called interchangable.

[bjensen83]

Personally, i would've gone with TransGo or TransCo shift kit. they tend to last a lot longer than the B&M, but to each his own. Nice "how to" none the less.

[Oldsman]

there are only 2 shift improvers for our transmissions. and transgo or transco isn't one.

what do u mean "last longer"? Do the B&M's just STOP working?..

[Oldsman]

well it has been on my car for almost an year and working great. the only thing that may not last it the switch if you wear it out. but haven't heard anyone have problems with them going out.

[1WhiteOSV]

ya..that's what I kinda figured. I installed the shiftplus on my Alero 2day (3400) and it works great! I am still going to mostly keep it OFF but setting 1 is ideal for the casual driver/racer. IDK about setting 2...I can chirp my tires from 1st to 2nd in setting 2 but I also hear a squealing/grinding noise from my tranny at the same time (DEFINITLY NOT GOOD) so I keep it on setting 1 when in use or off if I am just crusing and not expecting to race or need to go fast. I also don't know what those pics are of the installation. I had Dave from High Rev Motorsports (RSM Racing) help me install mine and we tapped into the red/black and blue/white wires on the back of the ECU under the driver side footwell. It took seriously like 10mins TOPS. I can post pics if needed. As far as needing to tap into wires all the way up under the hood on that transmission harness..idk what that's all about. Maybe you gotta do that for the 4cylinder applications.

[Oldsman]

well those pics are from installing it out under the hood. the 3400 tranny has the same plug. so you can install it the same way.

if you don't know where the wires are at the ecu then you can do it under the hood at the plug.

actually out at the plug didn't even take 10 minutes to install.

[Oldsman]

the grinding noise it the pump. on the higher setting the pumps makes a lot of noise. kinda like the auto trans does with the pump all the way turned up.

[FormulaNERD]

summit racing also has it for 39.95 here (http://store.summitracing.com/partdetail.asp?part=BMM-70380&N=120%20400004%20300209&view=33)

[1WhiteOSV]

the pump on what?...the tranny?


I also like installing on the back of the ECU because you can keep the unit inside the car with you and control it from inside AND you DONT have to run wires under the hood :thumbsup:

pics of splice locations would be great...

[1WhiteOSV]

I will post pics 2morrow when I get outta class....no worries, it's SO easy to install.

[Oldsman]

it is the pump inside the tranny.

i do control it from inside. far as running wire out to the engine compartment. just followed amp power wire. piece of cake.

besides they give you enough wire.

but hooking it up either way will work.

[1WhiteOSV]

oh..cool...i didn't know how long the wire is when it's new because I bought mine used and it must have been cut to length because my wire was only about 4feet long.

[Oldsman]

mine was like 12ft long...........lol

[1WhiteOSV]

LOL

[1WhiteOSV]

Here are 2 pics of the install...........I will post instructions on the 2nd post

[1WhiteOSV]

Installing the B&M ShiftPlus on a 3400 V6 at the ECU instead of under the hood (both work fine).

1. Locate ECU on the driver's side. You'll need to remove the plastic cover piece by removing the push-in retainer. This is all located down in the footwell by the pedals.

2. Locate large wire harness coming from the back of the ECU. You'll need to remove the 1st layer of electrical tape that is wrapped around the harness. Once that's done it's time to locate the 2 wires you'll use.

3. Locate the wires in the harness on the back of the ECU that you'll use. To make it easy and so you don't have to guess which ones they are (because there's multiple wires that are the same color) you should go to the bottom right hand corner of the ECU (as you're looking at it from in front...bottom left hand corner if you're looking at it from behind...THIS IS CIRCLED IN GREEN IN THE 2ND PICTURE). The wires you're looking for are striped. One will be a LIGHT BLUE w/ a skinny WHITE STRIPE and the other will be RED w/ a skinny BLACK STRIPE (SHOWN WITH GREEN ARROWS IN THE FIRST PICTURE ABOVE). These will be the wires you splice into.

4. Splice into the wires. You'll want to get some nice wire strippers or VERY CAREFULLY use cutters to strip back the wire casing a little bit on each wire for the B&M wires to splice into. You will take the RED wire on the B&M unit and splice it with the RED w/ BLACK STRIPE wire on the back of the ECU. Then you'll take the BLACK wire from the B&M unit and splice it with the LIGHT BLUE w/ WHITE STRIPE wire on the back of the ECU. Once both splices are done and electrical taped back up for protection, you're finished!
**to make installation much faster and cleaner, I would recommend getting some self-splicing connectors to use for the connections**





All installations are done at OWN RISK. I will NOT be held responsible for any type of harm or damage caused to ones equipment or vehicle. Thank you!

[1WhiteOSV]

I also apologize for the pictures....my digital camera sucks a lot and doesn't take very good close-up shots for some reason. Sorry guys! If you absolutely can't use those pictures or need further explaination, just let me know and I'll do the best I can!

-Adam-

[bjensen83]

Um. i installed the shift kit on my V6 2001 Alero, and i don't feel any difference from off than in setting 2.... what's wrong, i spliced the black wire into the light blue/white stripe wire, and the red into the red/black stripe wire, and still doesn't work. i've checked it several times and still doesn't work.

[Oldsman]

if it don't work then you hooked it up wrong.

there is 2 blue and white wires coming from the tranny. that is why i said go to the plug under the hood because you can go by the pin location as i stated in the how to.

[bjensen83]

:) kk. I think it is hooked up, but it drives bad now, the RPMs fluctuates alot when at a stop light, but i'll rehook it up. thanks bro.

[G3m1n1]

I recently hooked up the B&M Shift+, but since I can not see the pics that Oldsman posted, I hooked it up under the dash like 1WhiteOSV showed. I'm fairley certain I got the correct wires, but I'm not noticing a major change in the way the car shifts. I seem to have a little better acceleration, and when I really hit the gas I shift to 2nd at about 6k RPMs. Oldsman, could you email me the pics that you had posted at the top of this topic? I'd like to try hooking it up under the hood to see if it makes a difference.

[Oldsman]

this is the plug

[Oldsman]

after the install with the provide connectors

[Oldsman]

here is the plug and wires to hook up too.

notice the rotation of the plug and when you get the plug to this point you will be able to see the lettere on the plug by the wires

[Redog]

OK I found the plug OK and found the wires.

I saw 2 reds and 2 light blues One red with the black stripe and the light blue with the white stripe, the other two looked plain. Do these other two have stripes that I may not see.

Also, 3400 guys, have any body have any problems with location since it's right near the a rad hose and exhaust heat sheild?

[jamcllw]

I've never had a problem and it's been there well over a year. I put some wire loom around mine.

if you can't see the pin letters, then look at the rotation of the plug and then look at where the wires are.

[Redog]

Hooked it up last night and damn do I feel a differnce.

Plus at half throttle, I lit them up though an intersection. It had just got done raining but still :thumbsup:

I don't get the hard thump in stage 2 shifting out of park into reverse but I feel it shifting, and I feel as though it's too hard of a shift. Plus chirping tires in a school zone, not good

Going to the track on Sunday, I think this thing will help a lot. If the weather holds true to the forcast, I'll run between 15.50 and 15.70 without the shift kit

[Oldsman]

hope you can get to track test it.

[sofa]

i recently hooked mine up under the dash as stated and it isnt working ill have to try the other blue wire tomarrow..i shoulda went to the tranny plug but now i cant cuz i cut the wire to short lol if it doesnt work tomarrow time to bust out the solder. thanx for the pics and instructions guy HUGE help. its nice to see this comunity get along so well.

[wy3134]

Let me ask the benefits of going with a shiftplus kit over staying with what came with my car? also if im looking into heavier mods down the road, is it worth getting this kit?

[FormulaNERD]

hey man, if you decide you want one, i'll give it to you for 30, and if you come down i'll help you hook it up.

[wy3134]

ill make it a point to come down and party with u guys next semester and perhaps we shall see how things are goin and if you still have it, then I may go ahead and do that! although i gotta recoup this $1200 in purchases the past couple weeks lol (carputer and nitrous)

[sofa]

this b&m is very wierd. it seems like either you dont feel it at all or sum ppl it hits real hard. i just finished installation today and i feel a bit of a differencve and its on stage 2 the connections are solid and it is working because. when i go from off posistion to stage 2 the lights dim abit so it is getting power. i dunno it works abit n ot as i thought tho.

[Oldsman]

the lights dim? are you sure you got hooked up right? becuase the lights should not do that. where did you wire it into?

[FormulaNERD]

when i first hooked mine up, the connection was there, but not great, and it shifted harder, but not as hard as oldsman said, then i fixed the connections to get a more solid connection, and it works alot better.

[sofa]

i hooked it up under the dash to the blue wire w/white line and red wire w/black line. solid connection how many other wires are those colours cuz i couldnt find any. and my lights dim slightly just cuz its drawing power i figure. i dont think its working as it should but now i dont have enough wire to run it to the tranny plug. guess ill hqave to make up an extension.

[Rubered00]

got a problem guys....i just installed and i think i know what the problem is and am going to try fixing it but after installing my traction control light stayed on all the time???? does anyone know what i did wrong???

[eag182]

Old thread...yes, but here me out.

If you have the 3400 and you are able to connect this thing under the hood per oldsmans instructions, you must have incredible small hands.

I just hooked it up under the dash and I felt a little difference in setting 1 (though now I think it was all in my head) and no difference in setting to. Oh well, I guess I spliced the wrong wires. There is definitely no chirping, of any sorts with my setup. I think I'm gonna try again now.

edit> i cant even find any other wires of these colors, so i guess ill just sulk

[1WhiteOSV]

I don't mean to make anybody feel dumb IF this is the case...BUT! For those who feel it in setting 1 but not in setting 2.......are you shutting the car off for about 10 seconds at least THEN flipping it to setting 2 THEN starting the car back up? If not, then there's your problem. You gotta switch the modes with the car OFF. Now over time for some reason, I was able to flip it on the fly but that was after about a year of having it on my alero...kinda weird but for those just installing them...you have to have the car off before you can switch settings.

[1WhiteOSV]

also....maybe this was due to my 235/45/17 nitto nt-555 tires but I had a pretty damn fast n/a alero (the fastest lol) and I only chirped my tires a small handful of times even in race mode.....so don't expect to be able to every time by any means

[eag182]

car was off, still no difference

[cannaert]

Well i got one for you. Ok just put mine in as well. I when i turn it on and start to drive it stays in Frist gear. Wired up like Oldsman did I might tak it out and do it like 01WhiteOSV did.

Quoted post


sounds like it is wired up wrong.

don't go by the wire color at the plug but the pin location. this is what is important.

i would double check the pins, the wire color to the right pin.

also did you disconnect battery for 20-30 minutes before you tried it?

[cannaert]

No i did do the battery. Thnaks oldsman Ill try that in the moring

[sofa]

Old a$$ thread but to help anyone out when i hooked it up the first time it was into my A/C lol. make sure ur a/c works if it doesnt ur on the wrong wire.

[Oldsman]

how did you hook it up to your a/c???????????

[sofa]

The blue wire under the dash i suppose. its nice out today im going to try and figure it out maybe the other blue and white? lol. well see.

[sofa]

i got it guys theres 2 red and black wires down there. the one furthest left is the right one.

[Oldsman]

that is why i ran it to the tranny plug. it is a more certain way of thw correct wires.

[Cliff8928]

Maybe this will help.

[sofa]

w00 not at all lol. yeah oldsmans right,run it to the tranny plug. under dash is hard to get @,

[AlbinoMonkeyRat]

I just bought one. Not in my possession yet...just doing some research.

Is the tranny plug the one almost directly behind the driver side high-beam light? If so, this shouldn't be so hard to splice it up.

Mounting will be my issue. I don't know where this grommet/hole in the firewall is...

no not really.

it is by the radiator hose on the driver side. find where the hose meets the rad then follow it back and you should see this.........

[2fst4u]

has anyone else experienced a trac off, SVS light, and ABS light from the shift kit? the new tranny i put in hates my shift kit. apparently there is a tech bulletin about the solenoid that controls line pressure in the 2000-2003 aleros, all automatic trannies. i can't drive with mine on anymore.

okay. Yeah, I got the plug. (next to the battery) Where's the hole in the firewall? lol

Quoted post

[2fst4u]

the hole you want to use is the main wire grommet on the firewall. it's on the driver's side on the firewall. use a coat hanger to bull the wire through from the cabin side. this will keep all the electronics on the inside of the car, and the wiring in the engine bay. let me know if you need more help.

my trac off light goes on but that is it. it does cause a soft code.

[AlbinoMonkeyRat]

I only get the trac light in mode 2. ;)

[rogan19]

will this work on my 2001 auto 2.4L ?

[2fst4u]

sure will. no problem

[rogan19]

nd how does it chirp

do you drive gear to gear or just leave it in D drive

[2fst4u]

i downshift quite regularly, but you can just leave it in drive. it will only chirp the tires if you have supporting mods. it won't alone give you power.

[AsianAlero]

ok sorry to bring back old post but is the install the same for the 3400??? thanks

[Oldsman]

yes.............

[AJules]

just got one today and I'm trying to install mine

how do I get this little black part off?

http://i33.photobucket.com/albums/d70/8GED8/shiftplus.jpg

nevermind, got it off

what did you use to connect the wires though?

[Oldsman]

i used the supplied connectors

[AJules]

yeah, I don't have those...

could I get them from a store or something?

[DOHC_tuner]

im interested in this too but first I have to finish the dam motor rebuild :)

[Oldsman]

get whatever splice connectors the store has and use them.

[Stiddie]

any problems if with this and 04's 3400's before i go and buy this

[Redog]

Nope, but once you put it in, don't take it out.

I took mine out once becasue the dealer said it was going to void my warranty, and when I put it back in it's wasn't pretty. I couldn't get the connection right again and I had bare wires and so on.

[Shiwnath]

^ didn't you have to take it out after tuning your PCM anyways?

[Hellfire5670]

Red dog you said you chirped your tires and your car is stock? I really want to get this for my car when i get it running again.. I have several chips a little crappy vortex supercharger:S headers cams and all that coming soon and i wanna just put this in for the winter.. does it make a real difference?
