What is being talked about in the original post is a ; "constant pressure " valve body.

TCI modifies a v-body for full main line pressure all the time. The TV circuit still operates as original with shift timing changes as the cable is pulled .

THe problem with the constant pressure v-body is line pressure is very high all the time. Depends on the boost valves installed to the max pressure that is reached. I have seen 320psi max pressure with the large boost valves installed.

High pressure creates harsh shifts , harsh engagement , higher oil temps.

Dont worry how old you are... it is the mileage on your body that adds up.
