55 ultramatic problem

Posted by 55clipper On 2010/6/27 13:16:53

About two years ago I had my Ultramatic rebuilt locally.
It shifts beautifully now. But, the thing still moos when it locks up. I believe this is a torque converter problem.
It still leaks oil when not running. When it was rebuilt the seals on the selector shaft and throttle pressure rod were replaced as well as the seal on the bell housing. I am thinking this leak may come from the torque converter. Maybe there are some bushings on it or seals. It has also developed a problem when I come to a stop. The engine shutters and shuts down. I can overcome this by goosing the engine. I feel maybe the thing is staying locked up.
If I shift to neutral before stopping, the thing is ok.
Any ideas will be appreciated. I had a similar problem on an ultramatic I rebuilt myself many years ago that I corrected by adding a can of Slick 50 transmission additive to. Tried it this time with no luck.
