The linkage adjustment is to reduce engine flare. I can't see why your throttle pressure setting would affect your parking pawl whatsoever. That oil pressure reading when warm is a bit high but I doubt it would affect anything.

Addressing the over rev "engine flare" during low to high shift.
I realized after the trans rebuild, I had not adjusted the throttle pressure lever and linkage which led to the significant engine flare. humanpotatohybrid guided me in the right direction to adjusting it. Took about 10 minutes of testing and adjusting. Now it is operating properly. It required adjusting the linkage back nearly 1 inch and now works great. I will check the exact position of the lever arm on the trans at its current working position for documentation.

Can you feel the transmission shift at roughly 5mph when slowing to a stop? If so, you overshot the throttle pressure setting.
There is a valve that retards the low range band operation when you are off the gas. If the throttle pressure is too high then this valve will never actuate, resulting in a harsher low range brake band application at the 5 to 7 mph downshift.

Great info.
I do not feel the car shift into low when slowing to a stop, so hoping I've found the sweet spot. I ran through different spline adjustments for the throttle valve shaft lever on the trans today. It did not like any other setting than exactly where it was originally (which is hard to explain.) The car would not shift out of low no matter where the throttle linkage adjustment was, unless I selected ^D. What I can say is the original setting holds the throttle linkage cross shaft connection above the distributor. I'll post a pic as well. It shifts great at any throttle depression.

Just replaced the manual shift lever and throttle lever shaft seals (with the trans in place). Wasn't too complicated, just woulda been much easier while it was out.
While I was in there, I looked deep into the "sticking in park" parking lock pawl issue. What I found is the pawl engages the lever properly, but as Ross stated, It looks like it may be travelling a degree or two further than it needs to. The pawl is locked in that position and does not go past it since it is against the spring pin. I tested engaging the parking gear at different pawl positions and found when it is closest to 90 degrees, it will not stick. So, I came up with a temporary solution using a hard stop for the shift lever. Originally, there was a metal plate already bolted across the frame cutout. I drilled a hole and made a stack of washers with a rubber one on top for the lever to contact. The linkage pin was temporary for testing as pictured below. It now works as intended however, catching the parking lever tooth into the gear has to be perfect so the car does not continue to roll. E-brake ensures it catches and holds.
