C4 Issue

I have a C4 with a reverse manual transbrakre valve body. The issue I am having is the transbrake will not hold the truck(jumps forward), and third gear is slipping. We did a line pressure test on it and the results were as follows(all readings taken Park 200 psi
Reverse 140-150
Neutral 200 psi
1st 200 psi
2nd 200 psi
3rd 150 psi

In reverse if you bring the rpm up to about 2-2500 the pressure shoots to 400-450 psi, all other gears go no higher than 225 psi. Also with the transbrake engaged the pressure shoots up to 400-450 psi.

Any ideas on what the issue is?
