^^^^^^^^^^^^^^^^^^^^^ This, seen it dozens of times. Often caused by chassis flex, mount problems, or in a dragster, tire shake.

Re: Help-Powerglide-big leak when on the brake?
Seems strange that the case should fail at that seam line. What line pressure do you run in Rev, and when the Trans Brake is on? Maybe the pressure is too high and stresses the case.

Re: Help-Powerglide-big leak when on the brake?
Dye immediately showed when on the brake. dont know what pressure it is set at. Since the ultracase isnt available in time for a 3 race weekend, I ordered a 1 pc sfi glide case and have the trans pulled. Appt made with my trans guy for wed night if fedex shows up on time. He will swap everything over while I wait for $100. Ultrabell will be for sale...lol. dated dec 2013 I believe.

Check the driveshaft for run-out (before you pull the transmission back out) and get it balanced if you have time. I had an off center pinion yoke that was causing run-out and it killed 2 cases for me before I fixed the issue.

A bent drive shaft will do it.
