actually it's the other way around. autos with bigger tires build more heat which in turn hurts the tranny, plus the gearing in the autos makes them "slushy".
a stock manual XJ will outrun a stock auto XJ because the gearing in the manual transmission itself is better than the gearing in the auto tranny, plus if you have to, you can push the manual a little harder and further than a auto since you control the shift points. and you don't really have the heat issues with the manual trannies as you do with the autos.
FoMoCo said:the truck probably weighs at least 1k lbs more than the xj and the 4.0 has like 85% of its peak torque off idle, in that situation it is all about torque to weight ratio
True but I always heard that the 4.3 is a torque monster as well. Hm..
It'd be interesting to throw the 4.0 in there and see the difference.

Actually it would be easier to find a 2.8L V6 XJ and put the 4.3L gm in there. Oh, wait a minute, is that 4.3L in the GM one of those straight 6's ?

My '94 with the AX15, 4.0 and 3.07's, had 215/75/15 tires on it until last weekend. I always thought that fifth gear was kind of weak. Now that I have 30x9.50x15's on it, 5th gear sucks. I also lost 4th gear about 2 months ago so going from 3rd to 5th to get on the freeway blows.
This is the only Jeep I have driven and it doesn't seem quite as powerful as everyone makes them out to be. Perhaps there is something wrong with mine. I am still doing maintainance on it to be sure its completely up to snuff. Just need a new O2 sensor and the MAP sensor is still original. It has been rebuilt (saw oversized pistons when I did the head gasket) but I dont know how many miles are on the engine.
I drive up a steep hill on the way home everyday and in 3rd gear at 2000 rpms, it would barely speed up with the 215's. Now its a 2nd gear thing unless I want to slow down.
