Variable hydraulic lifters for 440 engine

Thx AJ,

So the only difference between Park and Neutral are that in Park there is a pressure bleed off and the ratchet lock is engaged.
I would say when the TC sprag is not working (either stuck or able to rotate in both directions) that this would give issues all the time?
From the video, that when coming from a standstill it multiplies the torque as the stator is in a static position, the car would be really lazy at take off if the sprag was malfunctioning.
If it would be seized up guess this would show problems at higher constant speeds?
So as you said, a warped clutch would be likely, and a tight converter also as i don't know what type/model it is.

I checked on some pictures again and i can see a number stamped in the converter, i never noted it down but it is on the ring gear.
I removed the cover and cranked over the engine to find the numbers which says the following: 47339E12 CH RG 130
I will do some searching for these numbers and might find somthing.

It seems i cannot go back to work for some time due to this mad pandemic so i will see and pull the car from the garage and perform the test and see if i can find the number on the converter.
