Without a doubt, the best thing going for that transmission is a shift kit from Transgo. The Corvette servo is a help but usually the thing for a 700R4 - not sure if they ever put a 200R4 in a Corvette. Grand National has the desired parts for the 200R4. Actually I believe you can actually leave a seal off of that servo somewhere that basically disables an accumulator, can't remember which one though - it's been a few years since I messed with one. Transgo is the ticket though. Clay

An accumulator is a hydraulic shock absorber. This would soften the shift for a smoother ride in a street vehicle. Disabling the accumulator would firm up the shift.

On the 700r4 I know disabling the accumulation can lead to broken hard parts.

The guy who did my tranny sells Transgo kits with awesome tech support, he is not the cheapest but the price is reasonable and the tech support makes it a great value.

My 4L60E is over 4 years/45K miles old and the car has made anywhere from a low of 260rwhp to the current around 400rwhp in this big heavy boat of a car and is holding up just fine. Point being this man knows his way around the GM automatic OD trannies.

No experience with GM transmissions, but Transgo is excellent stuff... Made a night-and-day difference in my 95 mustang, from the soft slow low rpm shifts stock to firm, quick shifts- made the car finally fun to drive!

Though I wish it had a 5 speed anyways Sad

Here is some information from a past post that may be helpful, especially if you intend to do other mods to the tranny beyond a shift kit. Clay
