like ^^^ said, watch it. I went to a oil change place and had them change my tranny fluid. They put in pennzoil, (factory weight according to them) about a year (or less actually) later, new trans.

according to the trans guy i went dry at one point, a few of my gears were melted, most all bearings were shot. the Mopar fluid is especially designed for the NVT-350(?) and has certain heat dissipation characteristics needed for it.

I just got my car back a week or so ago, don't know what the trans guy put in it (hopefully mopar), but it shifts "like butter" and i can't even hear the gears whine (i sorta miss that), whiny gears sound cool.

I had horrible shifting too, even after first rebuild, took it back, another shot bearing (right after being fixed too).

Has anybody ever heard of replacing a bearing in the trans with a bushing? Thats what the trans dude did! I'm not complaining, it feels and sounds great. (or lack of sound) I've never had such smooth shifts!!!
