Powerglide transbrake issue
« on: October 12, 2016, 06:54:32 AM »
I have an issue with my transbrake, i have 200 lbs pressure at the servo cover at idle.  Transbrake engages, pressure drops but only returns to 100 lbs.  Transbrake doesn't hold when i get on the converter(rolls forward) and then sticks, i need to rap the throttle a couple times to get it to release!

Any ideas? Valve body? Reverse apply piston?

The piston may be getting stuck in the case. It sounds like a tear down is in order, to check the piston and the apply circuit. It is possible the valve is not transitioning smoothly and is sticking a little in both directions.
