I have an 87 GTA with the 700 tranny and need to put a better servo in. Is the Corvette unit the best? Are there better ones (I seem to remember a billet one that was better than the vette one)? Finnaly, how much should I expect to pay for one? Thanks

 

I think you will be pretty happy with the vette servo, it helps quite a bit.

 

If you need one, let me know. I carry them in stock with all the necessary seals.

 

What does it do different then the stock setup exactly?

 

It increases the holding power in 2nd and it makes the 1-2 and 2-3 firmer. Do not use the aftermarket billet Servo. It is not "better".
