727 TF3 problems and pressure test

AJ/FormS said

Wired all the way back is like running the KD wide open all the time. The line pressure gets maxed out and the shifts are very firm, often borderline harsh. If the Governor is still working, the auto up-shifts will be quite late.
But there is nothing stopping you from backing off the tie-back some, just not all the way.

There was someone on the forum who mentioned using a choke cable to be able to adjust the throttle valve. I may look into that for occasional street use, maybe set it with a very limited range, half of the tv levers travel. Choke off position and the TV is maybe half way (find a happy medium) and then with the choke pulled out the tv is all the way back (for the track /spirited street). The TF3 is full manual, no auto function
