transmission problems

hey guys new to the web site and first post so here it goes. I was driving home from school today in my 1985 cj 7 when i started coming up a hill when all of a sudden my jeep comes to a hard stop and dies. pushed in the clutch and the jeep didnt move. started it back up and brought the rpm s up and dropped the clutch didn't move did it again and got it to budge only a bit so when i pushed the clutch in it rolled down the hill and out of the middle of the road. when it wasnt moving my shifter was stuck in first now its out but tranny does sound good when pulled home wont go in gear just grinds
any suggestion ??

Welcome to the forum!

I'll take a stab at this. You might try putting the transfer case in neutral and seeing if the problem is the same. If it is, then that points to the transmission as the problem. If the transfer case is in neutral and the problem goes away, then maybe the problem was downstream of the transmission (ie: transfer case, drive shafts, axles). It's a quick test to try.

Could be your clutch.

When you have it in neutral at the transfer box see if you can work through the box without the engine on. With the engine at idle you should be able to force it into gear with the transfer box in neutral without a clutch.

I have an '85 CJ7 as well. This sounds a lot like a clutch issue. As stated above, try neutral in the Transfer Case and if it goes away, look south if the tranny.

It wouldnt have stopped your jeep tho if it was the clutch.. the jeep is old enough that you can put it in first and just start it and it will start up and go if the trans is okay. The T4 is a pile to begin with also.. I'd bet your trans needs to be replaced. It wouldnt have ground on the way home either if it was just a clutch.

The VIN says its a 79 CJ

Thanks guys I didn't like that last post to much cause I took the t5 and Dana 300 out of my 1982 amc eagle. Fixed the problem runs great now. If this tranny does goes to I'm goin to have to buy a reverse for the t176 which was originally was in the jeep.
