Thanks so much for the helpful information. I will relay the information to the guys. They have the books out and are studying the tranny to figure out what's going on. I didn't think it was electronic either.
Thanks again!



If the pressure is there, the oil pump and the pressure regulator are working.
When you shift into reverse, there is a combination of valves that have to move
to apply pressure to the correct combination of clutches for reverse to engage.
The Oil pressure moves these valves ad well as applying pressure to the clutches.
If the valves are BINDING, no matter how much pressure you apply,
they won't move unless there is enough presure to overcome the BINDING force.

This is why it won't engage until you rev the engine over 2000 rpm.
Revving the engine spins the oil pump faster, and builds up MORE pressure.
