Hi, I posted a while ago about this rig that was given to me. It runs well but didn't go anywhere in any drive gear. Well, I had the transfer case rebuilt and threw it back in there and now it moves fine in reverse, but when I put the gas on in any of the forward drive gears, it revs first and then jumps foward and moves out but fluctuates the rpms abnormally while driving. It seems to be slipping or searching. I am assuming it is the transmission now and not the transfer case anymore. I am betting that the viscous clutches inside are not building up enough pressure. Any advice or pointers are very welcome.

Oh. It has a Torqueflight 727 Automatic tranny and 360 V8.
If I need to rebuild this tranny, does anyone know of a good used one that is for sale? Thanks! Ryan

First thing to do is pull your dipstick and take a look at the fluid and smell of it, an auto tranny thats burned up will usually have very dark oil (unless it was changed recently) and will have a distinct burned smell. It sounds to me like your tranny is toast, but check all your fluids and make sure they are all ok......

ok, I forgot to mention that I just changed the filter and the fluid in the tranny. Before I changed the fluid, I checked it and smelled it and it was a bit low but did not smell burnt . But, when I filled it to the specified amount(4 1/4quarts) the jeep would still not move. I checked it again after it warmed up and found that I needed to add almost 3 quarts to get it to the proper level on the dipstick(running of course). Then, I put it in gear and it moved in reverse and in the other drive gears but it was clear that it was slipping and searching through 1st, 2nd, and 3rd. So, does that clear the air for any other possibilities? Thank your for the feedback so far! Ryan

Needing that much extra fluid after a fliter change AND that it is slipping and charttering means you have bad seals in the tranny. Probably from sitting around a very long time. DON'T drive it slipping or chattering!! IF the seals have dried out, you might be able to re-hydrate them by running the car in park witht he correct fluid for 10-20 minutes idleing. That will get lots of fluid on them. But usually once they have dried out they are not salvageable.

It sounds like those seals at some point, have dehydrated and gone brittle. I have let it sit and idle a number of times for more than 20 minutes and it has not changed since then. I think it is time for a new tranny or maybe rebuild this one. Thank you for the input. I guess I will inquire in the parts wanted forum for a tranny for now. Ryan

Since it ain't working, why not get a rebuild manual for the tranny and see how hard it is to do yourself.

The thought had crossed my mind since I don't have anything to lose except sanity and time. The Wagoneer is not depended on anyhow. Maybe all I need is the suggestion to back up my thought.

You gotta start somewhere, and if the clutches aren't burnt and there are no foobared hard parts, you are only down the 80ish dollers for the seal kit if it don't work. Anyways, you dissassemble it leave it alone for a month forget how it goes back together, and any good tranny man will be able to finish it for you anyways... When I started rebuilding automatics, I knew nothing about them and had nothing to lose, same as you.

Good point. I am a student at a college automotive program(Honda training) specifically. I talked to the instructor of the Chrysler program and he said he wanted to help me rebuild the tranny. So I just have to pull the thing and bring it in and he will give me pointers. I have rebuilt Honda trannies but it should be nice to have Chrysler instructor to give me hand. Ryan
