Gus,
Reds Transmissions is a referral from Deiderich's a Tremec distributor in TX. I was considering changing to close ratio OD, but didn't.

I have not used either for transmission work. You may want to consider the TKX we discussed too.
I had a Tremec midshifter and my TKO shifted poorly. Gordon Levy hooked me up with a new shifter and it works great now. T5s are different, but there is a possibility it could be a shifter issue. You might ask about that first.
