Ultramatic - 1950 Transmission Fluid

Posted by otgdy On 2011/12/7 9:56:37

I read the post about using type-F transmission fluid and was wondering. I reciently replaced most of the trans fluid in my Ultramatic with trick-shift in order to hopefully clean out the governor. (post: od will not disengage).
Well this (TS trans fluid) worked when the trans had time to heat up. Still holds/stalls when cold. Could live with that except now the trans doesn't engage. If I put it in reverse (idle) it takes about 15 seconds till it very gently slides into gear (almost unnoticable) forget drive and or low it doesn't engage at all. Now do I go back to Type-F or is my rebuild with less than 200 miles on it trash ?

Yes there is fluid in it although that blue fluid is real hard to see on the dipstick. If I add any fluid it does end up on the floor BTW. Neat way to prevent the trans from being over filled.

Hopefully one of you has some good news.

Thanks
