I have had my car for a couple months now and it has almost 130K miles on it. Its a 1994 Z28, soon after I bought it I installed a B&M Shiftplus shift kit on it, it has an A4. It worked fine for almost 3 months now, but today I backed out of my parking space and tried to move forward and it slowly crept forward as if it was slipping. I turned back on the shift plus and it took off like normal. I can manually take it through the gears, but it won't shift before third with the shiftkit off. I doubt the transmission fluid has been changed for years or the filter, I thought this may help. I hasn't been acting like it was slipping or going out before today. Need help please.

 

On of your clutches is going. Sometimes when you modify your car, the extra power tends to find weak links. Its all good.

 

I have not done any mods to my car to make it more powerful, I think that it is just old and probably was poorly maintained by the previous owner. Would I have to get it rebuilt? No chance the PCM is messed up or anything? Daily Driver Need Help
