This servo is easy to install and can be done with the transmission in the vehicle. This servo will give your transmission 50% more apply pressure, just what you need to keep from burning your transmission up under heavy load situations. It evolved into several different versions of a two piece design. Also, since the servo isn't traveling as far before it applies the band, the 1-2 and even the 3-4 shift will be much quicker. While the 700R4 featured a one piece case for its entire life, the 4L60E started life as a one piece design. Right away you'll notice faster and firmer 1-2 shifts and even slightly better 2-3. This servo is a must for any performance, towing, RV, or off-road transmission, but would be a nice upgrade for any 700-R4 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 than stock servo pin to get your band adjusted to the right clearance. Should I be using thread lock, are the lock washers too thick and pushing away? Is this telling me the temperature of the tranny is too hot that the aluminum case is expanding and loosening the screws? This is getting exhausting.New USA made Corvette servo piston kit with a longer Servo Pin for the GM 700R4, 4L60, 4L60E, 4L65E, 4L70E, 4L75E THM700-R4 MD8 Each time I keep being able to tighten the bolts more. Latest try was 1/4 pure hi temp silicone cut to the gasket. Gave up on the aluminum pan since there is a piss hole at the front side that was blocked with that pan.

The professional rebuild screwed us over big time, missing a solenoid that allowed fluid to just churn in the pan which is why we never had good pressures or third and fourth gear, rubber o ring washer not on original filter that probably cavitated the pump, stripped case holes switched to helicoils, which never worked, opened up to the 7/16-20 since it was the smallest thread I could cut from the helicoil thread, opened the pan, punched new holes in a new ATD gasket, still leaked. Is there some secret to getting these stock pans to seal? Seriously, we had one ATD gasket that sealed fine, got another and no dice, got a rubber gasket with an aluminum pan, no good, went to all transmission silicone by permatex, nada.

Something else I do is since we get a ton of cores in, we get many with the expensive shift kits already installed so I'll pick through different colored springs for heavier ones to get from a firm shit to a bark the tires shift.

We dont sell the new Q: How much money are we looking at A: I bought mine on eBay, from Oregon Perfomance Transmission. I use a transgo one because there thicker and the stock ones will wear out where the check balls run. Q: What benefit does a Corvette Servo give you A: Youll get firmer, faster shifting, and about 50 more holding power in second gear, which is where the 700R4 or 4L60E transmission really lacks in quality.

Level 1 Stock Plus Mega Valve and Corvette Servo. Something else I didnt postis a valve body seperator plate. Some of the upgrades to the 700 Raptor below, don’t settle for less. Alot of our cores that come in are recent rebuilds that might have been in a wreck so there usually in good shape.
I have no problem using used frictions in my trannies but if it it a customers I am doing at home I use new. The overhaul kit I use usually is a paper/rubber kit and I use good used frictions and tumbled steels.
The zpak we dont keep, I buy mine from another company for 60.00 That band in the picture is a good used one for 6.00 The used beast shell is 15.00 or new 35.00
