A904 Line Pressure Issues - 07/27/19 11:33 PM
My Transmission was recently rebuilt and has a used throttle body. I have a TCI torque converter. It is all behind a 360. Oh yeah and a Lokar kickdown cable. (I know I know, I read the reviews and will likely be changing it out for the Bouchillion one or stock one.
So here is the problem: I have reverse and 1st gear...no upshift. I did some testing: fluid is full, line pressure is at 80psi in 1st gear @ 1000 rpm which is high from what I am reading, should be around 54 to 60 rising to 90 to 96 when throttle lever is moved. It doesn't increase as the throttle linkage is moved. This led me to check my line pressure in drive at 1600 rpm at the front servo release port. Nothing, nota, no reading what so ever, even when the throttle position linkage is moved.
Please if anyone has experienced this or knows what could be the problem please advise.
