1 Answer


hello acchill4u- Imagine in these days of six-speed (and more) automatic transmissions, that this car had a 3-speed. Reminds me of my old bicycle. This Corvette had what they called the Turbo Hydra-Matic, developed by General Motors back in the sixties. Gear ratios were 2.52:1 in first, 1.52:1 in second and 1.00:1 in third. Reverse was 1.93:1. Final drive ratio was 2.87:1. Good luck from Bovan.
