You can narrow the search down to your local area, or state, or region.

 

Or, check your local Junk Yards :brows:

i take it as you are looking for an aw4 if so you can take one from a junk yard they really never die just flush and swap the fillter in it

Craigslist is another good spot to keep an eye on. I use http://www.searchtempest.com as it allows me to search a bunch of different areas near my house. In the recent weeks, I've seen about 4 or 5 AW4's up on there ranging from $100 to $500.

thanks guys have any of you swapped one out...I'm just trying to figure out how hard it would be

[Pete M]

how rusty is your Jeep underneath?

 

Also, what makes you think the trans is toast?

[JeepcoMJ]

LKQ junkyard in rockford, IL is a u-pull-it type junkyard, and the trans is $90 set price.

 

there's a lower miles early 90's 4.0/auto in the hard there at least last time I was there.

it slips now and when its in reverse it sometimes dies while backing up... the jeep is pretty ruff we got it for 400 bucks

[Pete M]

Just wanna make sure that a different used trans will fix the issues. that's a lot of work to go though if the problem lies elsewhere. :(

[woody62]

do you think a flush and filter might fix it?

[Pete M]

If you dropped the pan, you could see if there's any material lying in it. What's the fluid look like on the dipstick? red? brown? smells funny?

 

Do you need this as a daily driver? or can it be out of commission for a while?

 

 

If it comes to dropping the trans, be very careful with the dip stick tube. I've read that they are fragile.

It's two pieces. One piece is attached at the oil pan and curves upwards to the engine bay. Shortly after the curve there is another piece that lies inside with an o-ring to prevent leakage. These two pieces are a real PITA to get apart sometimes. I finally gave up, applied some heat to where they connect, melted the o-ring and it came apart no problem. Had to get a new o-ring, though!

Before you do that do this:

 

It sounds like a bad solenoid or two. There are three of them inside and they are easy to change by pulling the pan. They can be checked at the TCU connector with an ohmeter. Each should read 11-15 ohms. When they go bad they usually short out causing all kinds of shifting problems.

 

And while you have the TCU disconnected, take it for a drive and see if you can shift through the gears normally using the shifter. If you can, it's normally a TCU problem of the above mentioned soienoids that the TCU controls. :cheers:

Seen how you originally asked where to get an automatic tranny.........

 

If you really want to check it out first, read thru this, it will take you step by step for diagnosing a problem -

But.......if it's slipping in reverse, I would think the tranny is shot :roll: That's usually the first thing to go south on the AW4 (and Ford) trannys.

 

There really not too hard to swap out, and there are a couple of write-ups on the DIY forum.
