Automatic for my CJ-7 - Pirate4x4.Com : 4x4 and Off-Road Forum

Currently I'm running an TF999 behind a 97 4.0L from a XJ (and in front of a D300). I want to put in a overdrive auto, what are the pros/cons of a AW4? How luch longer is it and how does it compair in strenght? Is there any other autos I should be considering?

Thanks,
Jason

AW4 is a tough tranny...the on in my wife's Cherokee has over 200K miles on it. Not sure about the size, but you will need the control module for it as well...the tranny is electronic. I'm not sure you will gain that much by putting in the OD. If the TF999 has a lock up converter, then I would not swap.

If you want to save money on gas....drive a little slower.....that will do more than a new tranny.

How can I tell if I my TF999 is the lockup style? Gas milage is not my primary concern but would be a nice bonus. I'm trying to keep the engine from having to run at high RPM all day when I use the freeway. Plus I can put lower gearing in the diffs and still beable to use the freeway.
