well while holding the brake park has 65-70 psi and all the forward gears gave 75psi including reverse, isnt reverse supposed to have 140 psi? if i rev up the rpms to around 3k the pressure will go to 225(and at wot while driving) but the needle is bouncing alot. the car wants to move in reverse but its not really... any ideas?

Presures sound normal bouncing is generally associated with slightly low fluid

i remember reading that reverse is supposed to have 140 psi while holding the brake. id like to get an answer to this before i pull it back out. maybe ill get lucky and itll be the reverse boost valve is stuck(its a .500 from the hd2 shift kit) maybe vince will chime in..

Reverse yes genrally will be a bit higher however like I said even with lower than normal line you should have reverse. Maybe a slipping reverse but it should be there.

I do have reverse if i rev it up to about 4500+ rpms but even doing that it barely moves, so its slipping bad,probably burning those new clutches up. its a lo/rev problem as i have no engine braking in manual 1. do they get fed fluid through the shaft/stator with the teflon seals?

If the problem affect manaul low and reverse then it has to be realted to the LOW/REVERSE CLUTCH.
OPTIONS ARE-
1-SEALS ON CLUTCH PISTON
2-DAMAGED OR CRACKED PISTON
3-MISSING LOW ROLLER SUPPORT SNAP RING (USSUALLY WILL CAUSE BIND UP)
4-PLATE MISSING OR NOT TIGHT AT REAR OF VALVE BODY JUST UNDER SOLENOIDS 3 8MM BOLTS
5-CASE CRACKED AT REAR (I HAVE SEEN THIS)
Theres really not much to the circuit below are flow diagrams for manaul low and reverse if they are of any help.
