Good catch, Ross.

2T300, I happen to mention this (and the consequences) in my video at around the 16 minute mark. It just so happened that the trans I was disassembling had that exact problem (though mine was misadjusted, not missing).

P.S. Some blue Loctite on that bolt would be a good idea.

Thanks for mentioning that. The old setup did not have that and I hadn't made one. I adjusted the linkage to prevent it from going that far.

I watched your video again to see the stop piece. Looks easy enough to fab one up and install.... Added to list today!

Check out the pawl I removed... Kinda explains some of the sticking in park problem? Not sure what that extra folded piece of metal is in there, but definitely was stopping the roller from rolling...

And yes, I use the high temp thread locker on that bolt for sure!

August 2024 - Ultramatic rebuild installed, not yet operational:

Rebuild went well and took longer than anticipated (but expected).
All recommended upgrades etc were performed, special thanks to HPH and the Ross Speedwell garage videos.
Main snag was rebuilding the reactor shaft assy, and waiting for parts.

Reactor shaft assy had to be assembled with the shaft in place while properly orienting the sprags. Then the top spring, washer and lock plate installed. Worked perfectly after that!

Installed new parking pawl/manual lever shaft, and completely new valve body.

Install back into the car went fine. Followed the manual for the 7 qt fill, then startup. Noticed the fluid level was high on the stick while running indicating no fluid movement. Ran thru a series of tests thinking the front pump was not primed, no avail.

Positive note: it no longer sticks in park! It locks, stays locked on sloped driveway, and easily releases.

Next, I'll try swapping back to the old valve body to test prior to pulling the trans once again...

In the meantime, I found a local shop that does media blasting/painting. Should be lined up for that next once this issue is fixed.

Removed transmission, disassembled once again, found I had placed the valve body gasket underneath which of course blocked all the fluid ports......

Put it all back together and installed. Works great!!!! The entire diagnostic process took me 2 days start to finish. Slowing me down was the reassembling/lining up gears etc...

Glad that's done...

Definitely would have had a much harder time if it wasn't for this group here.

HPH related to always have the drawing plates available when doing any work on this car since the manual vaguely explains things.... Golden advice!!!

Daily drives going well. A few things noticed.

- shift from low to high has over-rev under heavy throttle.
- Intermittently sticks in park (hopefully just needs a linkage adjustment).
- small amount of trans fluid leaks out of bell housing.

Otherwise, it's very smooth...

- Adjust the linkage towards the firewall 1/16" once or twice and this issue should resolve itself as long as it was set correctly to begin with.

- Is the shifter sticking, or the pawl itself? If the former, you can try tapping the pin in the smallest amount from the outside.

- There is a double bushing in the bell housing that is pressured up to 90 PSI when the converter circuit is on. Naturally the fluid leaks somewhat and would run up against the seal with pressure, if not for the drain hole that they drilled in the bell housing.
1. If the stub shaft was worn down, the seal could be leaking past that.
2. Rarely, the seal is installed poorly or the bore is scored, and fluid leaks past the outside.
3. Excessive pressure from a worn bushing, as described above. There is an STB somewhere on this advising that you can oversize the drain hole I think by 1/32". Or if the seal is installed too far down it can block the drain hole in the same manner.

Is the inclination of the car the same for the intermittent sticking in park?

I'm hoping the linkage adjustment will do the trick. It does not "feel" like the pawl is sticking.

The inclination of the car has not been the same when it has stuck. I will do more testing while engaging the parking gear on different slopes.

It could be the stub shaft worn from use. Not sure, but I will continue to drive it hard and monitor things as time goes on. We are in the queue with the paint shop and waiting for them to let us know when it will go to "paint jail"....

They will remove the engine and trans for a legit paint job, as well as blasting and coating the frame.

At that time, I wlll install the Jack VInes oil pump and service any other issues with the trans that may arise.

Linkage adjustment definitely fixes the sticking in park issue on any incline.

Everything else is working great.

The small trans area leak is minimal and subsiding. Break in period from fresh rebuild is what I'm chalking it up to.

Just going to daily drive it until paint to work out any and all bugs.
