Re: Ultramatic Clutch Disc and Linkage questions

What's odd is that if you move it right to neutral it works and the 2 forward gears seem spot on. Reverse seems like neutral.

Now i DO have only about 7 quarts of fluid in it so far, i was really only putting enough fluid in to start the motor for about 10-15 seconds at a time to test and tune things without hurting a dry tranny. Maybe i don't have enough going. Once or twice putting it in park didn't "load up" the drivetrain.

My tranny is an early 50 that had one of the thinwall bushings (of two), and not the other thinwall bushing. It has the 49 and 50 two piece tv rod setup. I have the clutch piston plate/driven plate in the converter that has tons of "teeth" with groves on the outside, not the later one to reduce bind. It has the 11" disc and not the smaller one.

So i'm thinking that if there's an "old style" anything with the ultramatic, i seem to have it. I don't know how to tell if i have a "sand cast" valve body, but Ross mentioned that the 5/16 dimension may not be the same for the sand cast units.

The tranny rebuilder did everything but the converter, so i can't speak to anything about link bars or bands, only that i asked him if they were adjusted and he said yes, it was totally ready to go except for the tv linkage adjustment and shifter lever/piston adjustment. He said his book didn't show the correct info for my tranny so he couldn't set it properly. Later i found the 5/16 dimension and set it myself.
