Hi, the part numbers seem to be different. You would at the very least need to reflash for the additional cylinders. I recommend getting a used computer at a salvage yard. If you can find one for your year and 5.2 liter engine, you may be able to use it without reflashing. A year either direction may also be fine, but 1996 or later would not be compatible. Please let me know if you have more questions, and thanks for using FixYa.

this seems to be because either the connection to the solenoid is loose or faulty or the solenoid is not activating. the transmission control module sends a signal to the solenoid to activate it. you get the light because the ecm detected that there is a a problem with the circuit. this is due to the fact that there is a voltage value to the solenoid and it is out of operating parameters

You need to have the vechicle scanned for codes.I believe you are going to limp in mode on the computer.Have them check all codes,transmmission and body along with engine.

Can I swap a 94 jeep grand cherokee laredo 5.2l engine and transmission into a 95 cherokee sport


You probably could with a lot of work. The Cherokee Sport has the 4.0l engine and since it is a 95, it may or may not be an OBD2 computer system where as the 94 will not be. Plus you are going to a much bigger engine. The computers will have to be changed and I am sure you will have to do a lot of fabrication with the motor and transmission mounts among other things. It can be done, but it would be a ton of work!!!!

I am putting a 1994 transmission into my 1996 jeep cherokee and I have 1 plug that is posed to be like a 10 prong plug but on the 94 it is a 3 prong plug. Do they make adpters for that or what should I do?


I hate to be the bearer of bad news, but that transmission from the 94 won't work in a 96. Probably because the 94 was for a Jeep with OBD I and your 96 has OBD II. I checked my used parts site and all that will fit is a transmission from a 96, maybe a 97.

Sorry, at first glance, I was thinking that you might be able to pull it off. But, having given it some thought....

To answer your question simply, the tranny will not work as it is. To my recolection, the transmissions changed midway through the 1993 production period for the Grand Cherokee. Even the mounts in your 94 had changed from the 91.

Having said that, there may very well be a conversion kit or adapter kit available to make this possible. But, I'm not aware of one and, based on previous experiences, I would not think it would be cost-effective or easy.

Good luck with your project.
