This servo kit is a must for any performance, towing, RV/off-road application, but would be a nice upgrade for any 700R4 or 4L60E. This is way too much travel, it should be closer to 1/16'. If you push in on your servo cover, you'll notice that it moves in around 1/8'-1/4'. It's almost more important to get the right clearance as it is to change to the Corvette servo. This package includes a longer then stock servo pin to get your band adjusted to the right clearance. P.S As far as line pressure here is some facts on the servo. If not pay a shop to install it like $35 tp $70 to have some one install it. The way that I did it, I used a strong piece of wood, kind of like the ones used in axes and stuff, then used a small piece of two by four and placed it againd the servo cover and used the my truck underbody support to make some leverage against the servo cover then placed the o ring and the retained. Also just to let you know that servo is very tough to put in and place the retainer ring at the same time so make sure you can use 4 hands, two to push the servo in while the other two puts the o-ring in and the retainer in. I had to put both on mine e when I did the change, but try the above mentioned, before installing. It has to have a 1/16 of an inch play, or so, not too loose or you'll end up burning that band. that way you wont put too much pressure in your tranny band.

That servo is tough, but before you place the seal on the cover, make sure you can turn your drive line ok, if it is too hard, use one washer, but if it feels loose use them both.
