I'm putting this out here because I don't want anyone to get confused the way I did;
Spectra Industries no longer makes a radiator for the manual version of the TJ. Instead they are passing of thie idea that it's ok to use the automatic version of the radiator in the manual vehicle.
SORRY, THAT LINE OF CRAP DOESN'T CUT IT!
We finally got all the way with it and had it bench tested/road tested under identical conditions. Guess what, there is a temperature differential of 15 to 25 degrees using the smaller (automatic tranny) radiator. Look don't take my word for it, contact Chrysler's engineering dept. Because they were more than happy to review the results. Knowing that the base of the loyalest customers, is gettign screwed in the aftermarket by some Canadian company that can't own up to it's disception.
However, if you scan the autozone web site, you'll still see their offering the manual radiator while supplies last.

Anyway, if your overheating and you've done just about everything else to try and figure out why? Take a close look at your replacement radiator and make sure you purchased the right one.
