does anyone know if there is any difference between a */c and non */c tranny for 94,and what isthe best rebuild kit to makethe tranny more durable for street/strip..thanx.

only thing i can tell you is yes, the trannies are different for */c vs. n/a. i know nothing of rebuild kits

Since yours is a 4T60-hd, all you can do is get a basic rebuild kit and a shift kit to go with it.
Here'* the shift kit:

Oh wait, I don't KNOW what kind of car you have...

please put your year and trim level in your siggy. kbye

There are hardened parts avaiable. Check on WillWren'* transmission rebuild on his 93 SSEi. For track and strip..that is the best one I've seen to date. If your car was newer...I would say Intense rebuild is the best one.

i have a 94 sc bonny with a slushbox for a tranny

ihave a o/d that works in the morning(30mi) ,and after work(8hrs)the o/d only works for 5mi) ,the tranny consistently does this every day??????
