Below are some common things that fail in the 4L60E and cause this problem. It probably goes without saying, but if you put the vehicle into second gear manually, you’ll still be able to get to where you need to go. If you end up with a bad sprag, the 4L60E won’t be able to shift into 3rd or 4th gear.

Is there a shifting module in the transmission?

There are no “shifting modules” inside the transmission. As Mr Zimmerman stated, the later units (renamed as 4L60E) used electronic shifting and pressure controls. The module which controls the transmission may be part of the PCM (controls engine and transmission) or a TCM (controls just the transmission).

When did the Trans have solenoids for shift control?

In 1993 the trans was redesigned and now has shift solenoids for shift control. No longer does it have a TV cable or Governor. The Governor was for road speed and the TV cable was for throttle input. Now the VSS (vehicle speed sensor) and the TPS (throttle position sensor) are the inputs to the TCM or PCM depending on model year to control shifts.
