Some people were helping me out on the last thread, but I didn't get much accomplished. I have an 85, 2.8L, Auto (tf904), with NP229 t-case.
My jeep WAS driveable when I first got it. Had acceleration issues, but it was driveable. I was going up a hill one day and it decided to not want to move. So I towed it home. I drained the T-case and found huge metal shavings in it. So naturally, I thought it'd be the tcase. I replaced it with a similar NP228. I thought all my issues were solved. I started it up, and it seemed okay. Putting it into gear, it would have a big THUD and lurch a little bit. It would drive, just not very fast, and kinda rough. I found out that this is because the tcase was in LOW. I don't have the linkage for the H-L selector, so I crawled underneath and pushed it into High range. I get back in, and the Jeep does what it was doing before - once in gear, it just sat there and made a weird grinding noise. When putting it back into park, it makes a grinding noise like it's trying to stop something (decrescendo) and then a thud.
Now, if I put it into LOW, I can drive it around. Although this is very rough on it so I have heard. It doesn't shift either. It just stays in first gear. What I don't understand is why the tranny would seemingly be in "okay" shape when the tcase is in LOW, but once the tcase is in HIGH, the tranny feels shot.
Does anybody have a clue? Is my tranny shot? Bad tcase #2?
