What version does Speed Inc. sell?
Both, I would think.
BTW-- as far as shifter noise goes- my problem was low tranny fluid level.
My GMM Race seemed to make a huge racket, especially in the lower gears. Having had nothing but prblems with the B&M coming loose and leaking, I thought I may be a little low on tranny fluid. So, using the jack-the-driver-side-up-only filling trick (thus ensuring that I'll get the Royal Purple level up properly) I topped off the tranny this morning- it was at least 3/4 of a quart low!
Took her out for a test run and was amazed at the difference-- much, much quieter, and even easier / smoother / slicker to shift than before. I still have knob rattle, but that's a future fix (gonna put a MOMO knob on it).
