*I personally prefer to use 80w90 as its more common, and generally cheaper. Also if your axle has a trac-loc/posi unit, a special additive is required.
**ATF+4 is a better replacement than ATF+3, it is normally recommended that you flush out ATF+3 and replace with ATF+4
***Actual fluid required will vary from vehicle to vehicle, always check the fluid level before driving your Jeep.
