So the manual for my 03 tj is pretty vague about the specs for this fluid. Is anyone using something other that the stuff right from dodge? Also what are you putting in T-case's?
Yeah, and the net is not much better! I have an '03 Sahara, and here is what I discovered:
1. You can *NOT* use ATF!
2. I tried the Lucas stuff (with an extra Lucas "No Foam" gear oil additive) and it was a disaster - and a LOT of foaming I might add!
3. I swallowed my pride and when to a Dodge dealership and bought the Mopar fluid. I have not had any problems (or regrets) since.
I should add that I had a shop originally change the fluid (which I provided) and they put in the ATF (I was having my Chrysler T&C done at the same time - hence the available ATF fluid). My 2nd gear started grinding (badly). Then I swapped it out for the Lucas stuff, but second gear was still grinding and I started to get some fluid leak. When I went to swap in the Mopar fluid (myself this time), I discovered that the Lucas was foaming so bad, it was coming out the vent hole on the top of the tranny!
I have not done t-cases yet, but I am thinking Mopar again.
That was my experience. I hope that helps!
