Replacing the Transmission
Yanked the old transmission in favor of a “new” one.
Read more below:
Unfortunately I was unable to quickly repair the existing AW4 by rebuilding the valve body, since I don’t have the time to rebuild it right now I got a replacement transmission and torque converter from a friend of mine. Before I put the “new” transmission in I replaced the front pump seal (most common leak point on any automatic transmission) and flushed the transmission coolers and lines. I don’t really have a whole lot of photos of this project because I was too busy working to take pictures, here is what I do have.
As usual click on any image to see it larger:
Rear of transmission dipped down, engine view.
Transmission dropped down with transfer case installed. To get the transmission to drop this far you must detach the transfer case shift linkage. I left the rear driveshaft attached to the transfer case so I wouldn't have to mess with the slip yoke boot.
Transmission about ready to be pulled, I really need to invest in a proper transmission jack
Old transmission out. As the Haynes manual would say "installation is the reverse of removal."

Update, 2.5.2010: Unfortunately in the rush to get the “new” transmission in I screwed the job up and sent some small pieces of metal through the planetaries. After removing and reinstalling the transmission two more times, once to reseat the torque converter and again to remove the 4th gear planetary and clean it out it still makes noise in reverse, first, second, and third. The good news is that the noise does not affect operation and there have been no problems in the approximately 7,000 miles I’ve put on the transmission since. I will rebuild the AW4 I removed from this Jeep and re-install it at some point in the future.
