C5 transmission problems

**Edgar Limon** · 12-16-2009, 02:18 AM

My car is a 1999 corvette amd pushing around 500hp at the engine and the transmission started to mess up after a week of racing. It has the stock trany and it's an automatic. The 3rd gear is starting to slip alot more. I can still drive it under normal conditions, but i need to race so i needed to know if i can just rebuild it stock or should i upgrade it. If i should upgrade what parts should i use. Thanks for any help.

With 500hp def upgrade, the stock auto 4 speeds can break and slip under the stock 350hp.

I wanted to work on it my self so what kits do you guys recommend. Ihave worked on other tranys, but is it complicated to put back the trany on the vette

well the trans is in the rear

I started to do the trany, but dicided to stop and put everything back because had a view problems along the way. FOund the Transmission replacement steps. Their is over 200 major step andI did not know you have to take off the whole rear of the car and need special tools that I could not get hold of. If anybody wants i can post steps for anybody willing to do their own trany removal.

Do you know how to work on THESE transmissions? This ain't a Turbo 350 we're talkin about here.

Yes i know how to work on the trany and i got my freind helping me he is a mechanic for chevy and as done many C5 and C6 tranys but the hard part is can't take special tools out of chevy garage.
