700R4 no line pressure rise

Hi everyone, I have a 700r4 that i just changed valve bodies on, After doing everything i put a pressure gauge on the main line pressure port, and i noticed the pressure was 75psi, but this does not change at all when i pull the TV cable tight, it just stays at 75 all the time. Is there something i could have missed that would cause this?

Are you sure the TV cable is connected to the Throttle Valve inside the trans?

many things could cause this problem;

wrong v-body installed.

Stuck inner TV valve...

TV inner valve installed incorrectly at retaining roll pin.

TV linkage not hooked up or installed correctly.

Gaskets miss installed.

just a few items that come to my mind

The valve body was off the same year tranny, everything looked identical on it, except where the lock up solenoid was. IT was just in the next port over. How do you verify that it is the right valve body the I took it back down and verified that the tv valve is installed correctly and its free, the gaskets appeared to be in place, the Tv linkage is pushing on the plunger when you pull the cable. Could something inside the tranny itself be causing this pressure not to rise? im stumped Also i double checked and all the check balls where in the right spots too.

HEy everyone just wanted to let you know that it ended up that the pressure was fine the whole time , turns out the pressure gauge was getting stuck at 75 and wouldnt read any higher, after having the valve body on and off about 3 times i noticed this...... put a new gauge on and it was right where it should be, the old gauge got the sledge hammer treatment and went in the garbage

Wow, what an exercise.

Faulty tools, appliances often get the coupe de Gracie with me drawing cross hairs on it with my .25-06.

Stress relief.
