Can I replace an AX4 with and AX5 in 1988 Comanche

I have a Jeep Comanche 1998 2.5L 2WD.

Question:  I currently have the AX4 transmission and it had went out on me the other night, was wondering with the AX5 would I need anything other than the transmission to make the swap.  Ive been told I would need a new computer for the overdrive?

Answer:  We can provide a re-manufactued A5 with a 12 month hassle free warranty. This AX5 will include all new bearings, gaskets, seals and syncro rings, it will be dyno tested before leaving the factory to ensure quality.  Order our part number MTAJ03 your cost is $1250.00 outright no core required, plus freight.  Suggest you sell your AX4 on Ebay someone may want it for parts.  You can see the other parts we can supply for the AX5 on our site.
