Well as you may have been reading my threads about my T56 shifting issues, and after trying Royal Purples Synchromax fluid and now Pennzoil's Synchromesh, on top of everthing else I've thrown at it, it is still hard to shift under hard acceleration. I test drove another 06 M6 Gto today and speedshifted the car through third gear three times without missing a shift and it felt great compared to my Cobra, "as far as the shifting is concerned". Will a GM T56 out of a wrecked Vette or GTO work in our cars without a boat load of drama, or should I look into upgrading to the triple synchros wich costs well over 2K. I'm guessing there are a few wrecked GTO's that could donate a good T56 for way less than 2K, but would it work???
