Corvette Servo Piston & Long Pin 700R4 4L60E 4L65E 4L70E 4L75E Automatic Transmission 2nd Gear

Product Details


Corvette servo piston kit with a longer ACDelco Servo Pin for the GM 700R4, 4L60, 4L60E, 4L65E, 4L70E, 4L75E THM700-R4 MD8

This package includes a longer than stock servo pin to get your band adjusted to the right clearance. It's almost more important to get the right clearance as it is to change to the Corvette servo. If you push in on your servo cover, you'll notice that it moves in around 1/8"-1/4". This is way too much travel; it should be closer to 1/16".

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. 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.

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.

This servo is easy to install and can be done with the transmission in the vehicle.

The kit comes with all the necessary seals for installation including the outer cover o-ring.

This servo works in all makes of this transmission. GM, Cadillac, Chevrolet, GMC, Pontiac, Oldsmobile, Hummer, Isuzu, Saab, including:

Beyond satisfied
This kit has extended the life on 2 4L60Es I have. 1st one slipped in 2nd under hard throttle, this brought I back as I hoped it would. Just bought my second set for a trans that had almost no 2nd gear at all. Was a hail mary attempt, and surprised the heck out of me. Now I can downshift under WOT and it holds like a champ. I know it isn't a complete fix, but buys me some time until I have the time to pull and do a full rebuild, but bet your bottom dollar these parts are staying in them! Even with their free shipping option, I had the parts 3 business days later. Zero complaints. Will continue to use these guys!

Best upgrade for the money
Took twenty minutes to install, I ordered the sonnax overdrive servo and cover as well. Worth EVERY SINGLE PENNY! My transmission shifts better than new. My usual upgrades I always run into complications, this one was straight forward with plenty of literature for your parts if you choose to use them. Helps to have an extra hand to hold your pry bar to install the outside ring, but otherwise easily a one person job. Plenty of horror stories about broken transmissions due to not properly seating outer ring. Check, double check, triple check that you've properly installed these parts! It's too easy and quite a bit cheaper to go behind yourself and fix any mistakes before they're made. Excellent products, shipping, and customer service. Will be ordering from OPT again in the very near future as I convert my Denali into a floor shift with a B&M truck megashifter and mesh it together like it came from the factory as a slap shifting, angry grocery getter.

4l60e corvette servo with longer pin
This works awesome in my 05 Tahoe. Installed with 150k miles on the trans and shifts quick and firm. My tahoe feels like a different animal. Well worth it. Comes with detailed instructions.
