Help-Powerglide-big leak when on the brake?

cad · 07-07-2014, 10:10 AM

Hi all,
Over the last couple of weeks, my glide has developed a leak. The case is OEM GM. We thought it was the pan gasket, but have now ruled that out. It is dry above the pan rail on the sides and front. It is only wet on the rear/driver side of the trans. Enough that the trans blanket and cross member are soaked after a run.

Testing with the front wheels up on the trailer tail gate, it is leaking when running and the transbrake is engaged. We swapped solenoids and no better. Since it was leaking, we didnt race and drove it into the trailer and I drove home. It did not leak in the trailer and nothing in garage after driving it from the trailer to the garage.

Trans was rebuilt before the season. It just started leaking about the 4th race into the season. I know that the solenoid has not been over tightened, but it is almost like the solenoid boss is cracked.

Just looking for any experiences that you've learned.
Thanks
Clark
