THIS WILL NOT WORK WITH 2.66 RATIO LOW GEAR T56. This one has good synchrony teeth, not excessively worn, but do show some wear. Up for sale is the OEM TREMEC 61 Tooth 5th gear 2.97 low transmissions in GTO, CTS-V, and Corvette. 61 TOOTH GEAR CONFIRM YOUR COUNT LOW RATIO BEFORE PURCHASE.
Good used condition from a 2005 Corvette Z51 T56 2.97 low gear transmission that was parted out. There is some burring I would probably clean up before install but still a very usable gear. And the best part is that its an OEM Tremec gear, not a cheap Chinese aftermarket.
