It is nothing strange when the 4L60E doesn’t move in any gear and shouldn’t be a cause for alarm.

You do not mention a 4x4 truck, I guess the transfer … So: you either broke the pump, not enough fluid in the trans, shift linkage not working, drive shaft not hooked up. The tranny is perfect at partial throttle driving around tow. I'm really hoping it's in the tune, and not mechanical. I took her car out to the track, and the thing won't shift at WOT from 1-2, or 2-3.
