Questions and Answers

Jeep Cherokee Transmission ID

Q. I have a question about a 1990 Jeep Cherokee Laredo, 4.0 liter fuel injection, 4WD, power steering and cruise control. I've never owned a Jeep before,and I can't figure out what transmission I have. It's an automatic transmission. I think it's supposed to be an AW4 but when I pulled it out, I looked at the ID tag and it read as is. Model #30 40LE Serial# 90C R 60418.

On the very top of the transmission it's stamped 30 80, and right above the model tag it say AISIN 89807. I have a book on Jeep and nowhere does it mention this model number. I have went everywhere on line looking. I just need this information so I can order a new front seal.

I also am starting to think that someone might have already replaced the transmission considering the jeep has 230,000 miles on it. Any help or info would be greatly appreciated.

Thank you,
Scott

A. Here is the application chart for what transmission went in where:

Comanche AISIN Warner AW-4
Loadflite/Torqueflite A-727
Loadflite/Torqueflite A-904-LA
Loadflite/Torqueflite A-904-T
Loadflite/Torqueflite A-998
Loadflite/Torqueflite A-999
Compact WAG
Cherokee
AISIN Warner AW-4
Loadflite/Torqueflite A-727
Loadflite/Torqueflite A-904-LA
Loadflite/Torqueflite A-904-T
Loadflite/Torqueflite A-998
Loadflite/Torqueflite A-999
J Series AISIN Warner AW-4
Loadflite/Torqueflite A-727
Loadflite/Torqueflite A-904-LA
Loadflite/Torqueflite A-904-T

AISIN Warner AW-4 Loadflite/Torqueflite A-727
Loadflite/Torqueflite A-904-LA
Loadflite/Torqueflite A-904-T
Loadflite/Torqueflite A-998
Loadflite/Torqueflite A-999
Wrangler AISIN Warner AW-4
Loadflite/Torqueflite A-727
Loadflite/Torqueflite A-904-LA
Loadflite/Torqueflite A-904-T
Loadflite/Torqueflite A-998
Loadflite/Torqueflite A-999

So, since there is only one transmission used made by AISIN, and ASIN is stamped on the transmission, I would say you have an AW-4 in there.

At 230,000 miles, it would not be surprising to me if the transmission has been replaced.
