Removing the Servo on a 4L60E Automatic Transmission. Removing the 2 – 4 servo is not that hard on your GM 4L60E Transmission.
First remove the snap ring, then pull up on the 2-4 servo with pliers to expose the o-ring. Now you can cut the o-ring and pull it out with some pliers. Then you’ll carefully remove all of the internal parts.
