I need to change the gear oil in the 1995 4.0 SE and was needing a little help locating the fill plug. Also, I am assuming this take 90wt just like my lt-230

I'm fairly certain that T-case takes ATF. I'm sure some of the others will know for sure or check your owner's manual. not sure about the where the fill plug is. On mine it's on the rear of the T-case towards the top (LT230).

ATF in the borg case, and the fill is on the back, similar to an LT230
