fransmission fluid spewing ultramatic

Posted by casey rog On 2014/2/20 13:56:53

I have a 51 300 with a 53 ultramatic. I installed the transmission last summer, drove it a few times with no problems or leaks.
This winter I start the car every few weeks to keep the fluids moving. Last week I started the car, ran it for about 20 minutes, (no trans fluid leaking). When I turned off the engine I heard a guirgling sound. Looking under the car I saw trans fluid leaking on both sides of the pan.
I know I torqued the trans pan properly and attached the lines properly since I pulled the engine.
I started the car yesterday (33 degree temperature, the first time the tempertaure was about 15 degrees), and the same thing happened after I turned off the engine: no leaks when it runs, leaks after I turn it off.
Unfortunately it has been too cold to get under the car and see exactly where the leak is occuring.
Plese help, I finally have the car running on all 8 cylinders after the rebuild, the trans ran like new after the summer, and I was looking forward to crusing a soon as it gets warn.
Thanks everyone in advance.
