First of all I wanna say I'm happy and proud to be a member of this forum. This is the first time I've ever owned a N-Body. I have owned W-Body (98 GTP) Coming from a Grand Prix I'm surprisingly quite happy with my 2002 3400 Automatic Black 4-Door. That being said. I bought this car with 160,000 miles on it roughly. When I first got it on the road it was throwing a check engine light. Scanned it and it came back TCS, MAF, and EGR. Changed all 3 and EGR is still on but I think it's where I didn't clean out the port. Not a problem, in the future it'll be deleted anyways.

Main concern and I've looked and forgive me if this question has popped up a bunch of times but I couldn't find any information that truly helped me. My transmission shifts (real) hard going through the gears. Then, at other times it won't at all BUT will kinda hesitate for a whole sec - second a half. Also the RPM when gaining a little speed (not stomping it) is real jumpy.

Has anybody had this problem or knows exactly what I'm talking about? I really really like this car. I've checked out sites such as Milzy Motorsports and Wide Open Throttle Technologies and the more I read and learn about these phenemonal 3 series FWD motors the more I wanna go rob a bank lol (j/k) But before I can go any further with my project Alero I have to get my tranny problem taken care of. Can anybody help me out??

I don't think cleaning out the EGR port will help it, but it shouldn't hurt to do it. Almost any sensor unplugged could cause the PCM (computer) to default to high line pressure for the transmission, but that means the wires at the EGR going to the computer are suspect as well. Try disconnecting the battery cable for a long time to see if the code disappears. Do you get a reading on the scanner for IAT (intake temperature)?

Also visit http://www.grandamgt.com/ ,another good n-body site.
