I have a CPT 200r4 NLU trans that was built for use behind my 455 GS , that I just installed in my 87 Turbo T. Before I installed it I changed the valve body and govenor with an EA BRC valve body and govenor, EA tv cable and a PTC 9.5 nlu converter. It has extremely hard shifts at low speeds, I have adjusted the TV cable many times with no change. I installed a trans pressure gauge and got the following pressue readings at 1000 rpm.
Park & netural 130psi
D1 & D2 240 - 290 psi needle bouncing
D3 & D4 135 psi
Reverse 210 psi
TV cable unhooked 120 psi
The psi readings are all about double what the factory manual shows.
The trans has a 500 boost valve installed would this cause that much of a pressue change and the hard shifting ?
