New USA made Corvette servo piston kit for the GM 700R4, 4L60, 4L60E, 4L65E, 4L70E, 4L75E THM700-R4 MD8
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.
Right away you'll notice faster and firmer 1-2 shifts and even slightly better 2-3.
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.
For the price, the Corvette servo is the best upgrade you can make to your 700R4, 4L60E, 4L65E, or 4L70E automatic transmission. Installing this servo in lower mileage vehicles can add years to your transmission’s life. Higher mile transmissions can also benefit and help to postpone a costly rebuild.
This servo is easy to install and can be done with the transmission in the vehicle.
The recommended servo travel is 1/16”-1/8”. Getting your servo within this travel range can make the shifts even quicker and add more miles and years to your transmission’s life. The long servo pin option on this item can help to get this travel within the correct range. We are finding that when using the billet overdrive servo in conjunction with the corvette servo, this correct travel range is crucial. Any travel over 1/8” can create a situation of no overdrive.
The kit comes with all of the necessary seals for installation including the outer cover o-ring.
