I need a little advice on my transaxle. I've got a 2000 GTP with just shy of 170,000 that has recently had some major issues. As of yesterday, the car won't leave neutral except in reverse or when put into 1st. When trying to accelerate in 1st it feels like a manual when someone is riding the clutch really bad. VERY slow acceleration. I can put it into 2nd and once it gets into 2nd gear, it accelerates normally. Then it has problems again when it makes it into 3rd. Again, the gas pedal is like someone has their foot on the clutch. 4th gear seems to be ok. I used to work for GM Powertrain so I have a good idea of how everything works and I think the clutch plates are shot but I just wanted to ask around before I condemn it. Could there be a problem with a solenoid, speed sensor, or ECM that is causing just 1 & 3 to act up? Do 1st and 3rd share any clutch plates or other components not used by the other 2 gears? I would tackle a rebuild myself but I'm hesitant since I live in an apartment and would have to rent a storage garage or something to do the work. Any recommendations or advice would be great.
Thanks!
