Re: Ultramatic Question

I did get back to the Ultramatic this past weekend.

Saturday:
Dropped the pan with the car up on jacks. With Type 'F' transmission fluid running down my arms I loosened the link clamp bolt, re-adjusted the control linkage so the the rear land of the control valve was sticking out of the rear of the control body exactly 5/16", re-tightened the link clamp bolt. Buttoned it back up tightened all 21 screws and re-filled the transmission. Did anybody pick up on the obvious step I missed? Cleaned myself up and started the car. I then realized I had made the adjustment with the car in Park (it has to be in reverse). I had no detentes in the shift at all. The gear lever just slid from park to reverse with no hesitation at all. The transmission didn't particularly like this arrangement. So...

Sunday:
Back up on jacks, re-drain the transmission, drop the pan, re-align the control valve to the requisite 5/16" after making sure the detente thingee is in the reverse position, re-adjust the gear shift indicator so it points at reverse for which I was now positive the transmission was correctly set. Put the whole thing back together.

Result:
Eureka! As Ross predicted and I hoped, all is working well. No more bucking in reverse. High is High, Low is Low and the starter lockout switch is also in sync with all the rest. I'm a happy (but physically very sore) camper.
