4l80e I just installed my 4l80e and it seems to shift good, the only complaint i have is it feels like there is a slight power loss. However I have a pressure gauge on right now and reverse gets good pressure 60-100 but everything else is low like 5-10.. could this be a bad EPC or possibly my gauge is broken? Like i said reverse works great and drive seems good shifts when it should, shifts feel a little soft but not slipping

Well i've tested and my gauge is fine, with the wire harness unhooked i get about 150 psi in park neutral and drive and about 300 in reverse. How do i test to see if the force motor is getting power? Does anyone know how many volts it should be getting or can you only test to see amps?? Is it likely the force motor or is a faulty PCM more likely?
