Most shift kits are designed to address the servo travel issue already. Please note: If you are installing, or already have installed, a shift kit, you will likely not need a longer servo pin. The clearance should be closer to around 1/16″. If it goes in more than 1/8″, you definitely want the longer pin. Just get underneath it and with a pry bar, push in on the cover of your servo. You can actually test your current travel now. The longer pin is designed to take up that slack and prevent the servo travel.
Once it is beyond the travel of the servo, it will burn up the transmission. By 100,000 or more miles, the band is wearing out and then you are at the point where the servo almost cannot travel far enough. Too much servo travel can cause a delay in shifting, a longer 1-2 and 3-4 shift, as well as a slide-and-bump-into-gear type shift.

Here’s how to decide.Ĭorvette Servo with Longer Pin (part number OPT-CV-Pin)Īfter a short amount of time, by 30,000 miles or so, the band has been broken in and the servo travel has increased a lot.

If you have already decided to install a corvette servo, your next question might be whether or not you should use the corvette servo with the longer pin instead. The servo comes with all of the necessary seals for installation including the outer cover o-ring, as well as three pages of instructions with diagrams. Our servo is easy to install and can be done with the transmission in the vehicle.

The corvette servo is a must for any performance vehicle, for towing, RV, or off road use, and is a positive upgrade for any 700R4 or 4L60E transmission. The corvette servo will give your transmission 50% more apply pressure, which is just what you need to keep from burning your transmission up under heavy load situations. Right away you will notice faster and firmer 1-2 and 2-3 shifts. The self-sufficient repair of the automatic transmission can’t be carried out.Arguably one of the most inexpensive, yet most rewarding upgrades to your 700R4 or 4L60E (4L65E, 4L70E) transmission is the corvette servo. Dismantling transmission is time-consuming task, which is made only under the force of the special equipment.
Transmission 4L60E problemsĪt the same time, it must be said that due to the increased sizes the repair of automatic transmission 4L60E of this modification is more difficult. It means that you can repair the automatic gearbox GM 700R4. It differs by reliability and reparability. Altogether thes automatic gearbox makes a positive impression. It should be noted that certain functions of modification of transmission are controlled by electronics. This required the use of updated and enlarged in size solenoids. To ensure high-quality transmission’s lubrication solenoids channels were significantly increased. A principally new four-speed automatic transmission 4L60E was developed, which got a reinforced hydro block and a special pump’s design that allowed in a high-quality way to ensure engine lubrication. In the early 90s there was a problem of development of a heavy-duty automatic gearbox, which could be used in the Hummer cars equipped with the powerful petrol and diesel engines.
