Trans pressure test

[Kain]

Idle when you first fire 100 psi
Put it into gear and 25 no matter the gear. Put it back it no park
25 psi.

Question is is it valve body or pull and seals are bad on inside?

 

[Kain]

talked to a transmission guy he said if it goes into low 1 and engages it the low sprag or roller clutch(WHATEVER THEY CALL IT)
if not it is the forward drum needs attention

 

[Greg Ducato]

Those pressures are too low, what kind of transmission are you working with?

 

[Kain]

turbo 400

 

[Kain]

I am pulling it on the 4th and tearing it down

Doesn't sound like a broken hard part problem. Sounds like a seal has let go that bleeds off the pressure, the pressure regulator valve is boogered, or the pump is failing.

Seal in forward clutch , like one of the piston seals I am guessing
Tell you on the 5 th or 6th
