The stocker with a SPEC clutch lol. If it breaks, then dissect, and possibly the 5-speed getrag.

Jim over in PA and I were talking about it, and yes it's a "Chrysler" trans on paperwork, but it was developed by MB, probably using the same shaft's, gear's, material and coating that the auto's use. Which are the same for all 722.6 trans', which I'm assuming based on experience of MB members trying to build up the lower model trans to the higher model specs. The weak point would be the clutch.. only, since that's the only part different from the auto's. It's just like the Crossfire, MB said "if you badge it SRT6, then it's only 330hp" lol. At least that's my theory lol.

I might just try replacing the internals if it blows too. I mean there really isn't THAT much going on inside the manual trans, you know? Just shaft's, forks and gears.
