I just did the same this weekend past... went with Mobil 1, cuz there wasn't any RP around here. So far so good. I definitely notice the difference from the stock stuff. The only thing I would hafta warn, the darn drain plug is towards the rear of the car, I had the front jacked up quite a bit on jack stands and it was still tricky to get at lol.

I went with 3L (3.2Qts?)... darn americans lol... adopt the metric system already!

Good to see a fellow Jeeper thats into Mustangs as well... Im an XJ'er.

I went with Mobil 1 sythetic ATF, but I have a T-45. It better do something, its damn expensive.

yeah the xj has alot of mods for hard 4x4 stuff, not just dirt roads,

anyway i put the synchromax in today. i think about 3.2-3.5 quarts, the RP bottle was not marked off at 1/2 1/4 quart like most are..

i also decided to put on the second stock shifter rubber boot that goes under the "main" rubber boot to quiet it down some more..
