put in amsoil atf and friction mod around 20k then a year or two later switched to mtl. i just drained the mtl around 65k while it was sunny and as it was draining i could see right thru it like it was fresh fluid. car now has just regular valvoline atf for about 2 weeks to get it ready for another flush for the syncromax. mtl wasnt the greatest in the new england winter weather. supposedly the rp stuff is better in colder weather. surprisingly the valvoline atf has been shifting pretty well. i flushed my brothers mtx too. it likely was never done with previous owner. car has 50k and fluid wasnt too pretty when it drained out. both cars should be drained this weekend again for the rp fluid.
