I need a hand

So I have a 1996 rwd Jeep Cherokee with the 4.0 litre straight 6. For the life of me i can't find any transmissions for this thing under $500. I'm a high school student and I need to get this car running so I can take myself to and from work. Any help finding a new tranny or servicing the one I do have would be greatly appreciated. There is a transmission currently in the Cherokee. It knocks almost every time she changes gears (but especially so from 1st to 2nd). Any help diagnosing this would be a godsend. Last year she had a complete engine rebuild too so that side of things is a-ok luckily. This is my first time doing anything intensive mechanically, but I'm excited to get my hands dirty! (Repost in the correct category because I put this in the wrong place the first time)

Do the super flush and see what happens. What kind of shape is the current transmission fluid in? Red or dark brown? Does it smell burnt?

Why do you think the transmission has failed ? What inspection and testing backs up your diagnosis ?

The first thing to do is to determine exactly what is knocking ??? Inspect the motor mounts, and the bolts attaching them to the engine block. Inspect the bolts that hold the trans to the engine. Inspect the transmission mount. Inspect the exhaust hangers. Inspect the flex plate for loose bolts and/or cracks. Inspect the u-joints.

A faulty AW-4 transmission does not typically make knocking noises.


I very strongly suggest you invest $7.95 for a genuine Jeep Service Manual from www.pacificcoastmanuals.com and also use the Google to locate the AW-4 Diagnostics and Service Manual that can be downloaded for free.
cruiser54 and slickrock steve like this.

Luckily we already have one such manual. I'll start pouring through it to better understand the car. Once the NC rainy weather starts to go away I'll take out the tranny and give it a good long look for the things you've mentioned along with giving it a flush like the other guy said.

It sounds like a flex plate is cracked to me. That was what went on my 96, with an AW-4
