Need 3AT Hydraulic Circuit info
Posted 07 May 2006 - 09:20 PM
The governor mechanicals on my wife's 3AT are shot (pinion bearings or gov drive gear need replacing), and I am trying to get it limping along as a semi-automatic: Remove governor driven-gear, lock the governor circuit in "D" and shift the selector for lower gears. This is until I replace the transmission on one of the 4 vehicles that I have that need it. (Probably no time until summer, and my wife really doesn't want to wait that long. )
What I need to know is: What is the hydraulic circuit routing through the governor assembly when the road speed is high enought to select the "D" range (35mph or so)?
I have tried locking the valve assembly where I thought it should be at speed, gutting the valve assembly altogether (no restriction to flow exiting the valve), and sealing the 2 hydraulic circuit ports. None of these seem to work. I am beginning to think that rather than release pressure in the circuit (as I thought I remembered) it may need to route the pressure from one port to the other.
Anybody out there know or have an FSM handy?
