All 4.0L TJs (non Rubicon) came with either 3.07 or 3.73 gears, except 1997 which had the 3.55 option. It doesn't matter if they're auto, 5 or 6 speeds. I've had them all.Which is about where you wanna be if you had OD, or a few rpm less. I was under the impression all 4.0's had 3.55 or 3.73 gears. My old Jamboree edition CJ7 came with 2.73's. Kinda scratched my head on that one.
Nope. Just the 1997 4.0L TJ as an option. Lots of XJ 4.0s have them though.I'm thinkin 2.5 auto could have had 3.55 too
