The 1-2 shift failure on the 4L60E is often due to a faulty throttle position sensor (TPS). A more serious cause of 1-2 shift failure on the 4L60E is a leak in the 2nd gear apply circuit (servo assembly or 1-2 accumulator). You can test for this by using an external pressure gauge.

What makes a 4L60E transmission shift?

The 4L60, along with many transmissions of its generation, was controlled by a hydraulic system. This means that a series of valve pressures made the transmission shift gears. GM made the jump to electronic shifting control with the 4L60E (Electronic shifting control).

4l60e from 1996 held up well. Reverse kinda was finicky, every now and than it would slip but had a good life. I honestly think around 250-300k it should be rebuilt if its original.
