PCM 40a slipping in forward

I have a PCM 40A 1.23/1 transmission in my 96 sport nautique. It began slipping in forward but not in reverse. Changed the clutch plates and seals. It still is slipping. Once you have enough throttle it will go into gear until you slow down. Pressure problem? Any way of adjusting the oil pressure?
 
sounds like not enough pressure coming out of the pump....did you go thru the pump while the gear was apart?
 
I can't say I've read the PCM spec but 'looking at them' doesn't assess all aspects of wear.....besides the pump, the only remaining items would be the control valve (usually not an issues as long as the cable hasn't been altered) and the pressure regulating device....I think getting a hose and pressure gauge out would be a good start...
