Jeep's inline 4.0 is stout in the old Cherokee's (not Grand).
Agreed 100%. My '01 Cherokee Classic ran 15.89 in the quarter mile bone stock!
IMHO, it's that archaic Chrysler transmission that sucks all the performance out of the 4.0L in the Grand Cherokees. The little Cherokee XJ had a Aisin-Warner AW4 tranny in them (same as in a Toyota Supra), and they were awesome. Early '93 Grand Cherokees had the AW4 too, and they were much quicker than the later ones with the 42RH/42RE Chrysler trannies.
I really liked that AW4 tranny...Very responsive and shifted quick and firm. One of my favorite slushboxes to this day. I have never seen a single one of them break either. We've had Jeeps come in with 250,000+ miles on them, and though the engines are a little tired, the trannies are still shifting just fine, and had never been apart.
