So, this is actually in regard to the transmission I've already replaced. I bought a used transmission from a salvage yard w/ 88k miles supposedly. I installed it, filled it, and went for a short test drive. Whenever I engaged drive, it was delayed which can mean the clutch pack isn't doing so well or pressure is low. Anyhow, when driving around a few blocks, I lost all forward gears. Reverse still worked. The wife towed me back with another vehicle and pushed it into the garage. I bought a line pressure tester and when it finally arrived I tested it throughout the gear range and this is what I got:
P - 50 PSI then drops to 40 after cycling through the gears
R - 110 PSI
N - 40 PSI
D - 70 PSI
2 - 70 PSI
1 - 70 PSI
According to one thing I found on google, all those pressures are good. The book says it should be 50-65 P, N, D, 2 and 70-100 in R, 1. Calling the dealer and getting numbers from him, he was showing all gears at idle should be 80-100 PSI. That would mean that all pressures are low except reverse which would be high and that doesn't make sense.
UPDATE:
The ATSG says they are good except P, N(All gears except reverse should be 50-75 PSI and reverse should be 80-120 PSI)
Anyone have an idea what the issue could be?
After some reconsideration, I'm wanting to rebuild the old transmission that came out. The only problem it had was after awhile of driving it, I sometimes lost forward gears but M2 worked and after sitting awhile it would be fine again. It also made a grinding noise when in gear (It may have been anytime the engine was running, I don't recall now and I should have taken a video or something) since before this problem started, but has progressively gotten louder. I've already disassembled the transmission and it's actually in good condition which is why I want to return the used transmission I bought and just rebuild this. There were no metal chunks in the pan, but there was more than I would have liked for the other material that accumulates there. Also it looks like a good amount of the material was caked onto the bottom of the valve body, but a minute amount in the actual passage ways. I'm guessing that's all from the frictions? Upon looking at the clutch packs, the forward CP is burned some and some of the frictions are fairly worn (I can post pictures later).
