AX-5 5 speed manual
3.3 quarts 75W-90 GL4, or 10W30 (
NOT GL5 or GL5 compatible as incorrectly stated in some of the manuals). I highly recommend
Redline MT-90.
AX-15 5 speed manual
3.32 quarts 75W-90 GL4, or 10W30 (
NOT GL5 or GL5 compatible as incorrectly stated in some of the manuals). I highly recommend
Redline MT-90.
NV3550 5 speed manual
2.1 quarts. I highly recommend
Redline MTL.
NV1500 5 speed manual
2.4 quarts. I highly recommend
Redline MTL.

Redline MTL.
Transfer Case

1.1 quarts ATF+3 or
ATF+4
241

NOTE: The 231 and 241 transfer cases are fine with any type of good quality ATF. Mercon, Dexron, ATF+4, etc. are all fine. Only the automatic transmission is fussy about the type of ATF it gets.

The Jeep Wrangler TJ came with a HOAT coolant from the factory. I always recommend running
OE Mopar coolant or
Zerex G-05, which are both HOAT coolants.
