Product Details
New ACDelco 8680501 2-4 servo pin for the 700R4, 4L60, 4L60E, 4L65E, 4L70E, 4L75E automatic transmission.
The ACDelco longer 2-4 servo pin:
This pin is the longest pin from ACDelco and longer than your stock length. This pin will help to get your band adjusted to the right clearance.
Most stock servo travel is around 1/8"-1/4". This is way too much and should be adjusted down, closer to 1/16". At 1/4”, the servo is at its max travel distance and is dangerously close to allowing the 2-4 band to slip and burn.
This long servo pin allows for the proper pin adjustment. We find in almost all cases, just changing out this pin, will get you within the right range.
With the pin clearance adjusted down to the correct amount, the servo will not have as far to travel before it applies the 2-4 band. The 1-2 and 3-4 shifts will be quicker and the servo will not go beyond its travel inside the servo bore.
This pin can be changed with the transmission in the vehicle.
