shifting problems.....

[PrImEtImE]

Ok when at first the car is fine. After i'm driving a while it shifts kind of like the tranny is slipping....shifts very "clunky/hard" from first to second....a mechanic said he has the same problem with the same engine and nobody seems to think anything is wrong?? i had a tranny service done on it...still does it...only 48000 miles on the car its a 2001. ummm....anybody else with this engine "2.4 twin cam" have this problem??? or any advice?? a new tranny i'm sure would be SUPER expensive....

i have had the same problem, in the past,but for some reason its gotten better. i had a flush and fluid change a little while ago, but it didnt do too much. then i installed the B&M shiftplus, and only used it a few times, but after i did the tranny shifted very smooth. i dont know what exactly happened but its fine now.also, a very firm shit is better than a sluggish shift tho, sluggish would mean its slipping. if its not horrible, or making any noises or anything, i wouldnt worry too much. and ya a new tranny would be expensive. i got quoted 1G. dunno if that was reman. or new but either way, its money i dont have. good luck.

ya, it gets bad sometimes. that's the problem. but maybe i could try the b&m shiftplus. but is that gon wear n' tear on the tranny at all because my car is now a daily driver??? and how much and how easy is the install??

I have the same problem but its probably way worse than yours, and I have 117,xxx miles on mine, usually mine shifts so hard that it moves to whole engine/tranny and my trac off light comes on then it starts shifting quick as hell...my tranny is just done tho so idk what to tell u but that maybe u have a short in ur map sensor, its one of the things that controls how ur tranny shifts

sorry.. I just found your typo somewhat comical.

[whiterider00]

haha...wow, didnt catch that the first time...i wud still rather have a firm rather than sluggish shit...

mine does that sometimes too,but once its warmed up at normal temperature level unless something else like brake issues or something....it runs fine.

[jayson_waltz]

the trannys run at higher pressures untill they warm up just to be safer. thats why they shift a bit harder. you should drive it at 25 below F, trac control comes on going into second.

yeah, mine only does it after the car's warmed up. does that mean that the tranny could be overheating?

OK!!!! I have a solution or some or all of these trans problems!!!!
There on the intake pipe on the stock LD9 (2.4L) There is a 2 wire sensor this is the Air Temperature Sensor. THIS MUST BE PLUGGED IN AND WORKING. If you have the stock air box intake it is right on the L shaped hose by the power steering box. If you have installed an after market intake, there should be a rubber grommet on the pipe for this sensor. Make sure the sensor is there and plugged in. I have no clue what they cost but replace it if it is plugged in and everything, the trans WILL be a hard hitting shift out of 1st, like enough to shake the dash. all other shifts might be hard and might not. \
Let me know if this fixes the problem.
I had the same problem on mine

for a little while after i installed my WAI, the sensor was out of place, and about the time i installed the B&M shiftplus, i put the sensor back where it belonged. so i am assuming that was the problem. thanks.

What is the B&M shift plus, how does this incorporate in a "sealed" trans or do you have the 3400SFI?
