4 Speed Tranny - Close Ratio

Based on clues from the car I believe this Corvette came with one of two high performance engines. Clues include the Heater Delete option and the higher redlining tachometer. In either case, the high performance Corvette engines in 1963 came with a close ratio, aluminum, 4 speed T-10 transmission. In order to make this car period correct the existing 1975 L-82 transmission will be swapped out for this recently purchased transmission found on eBay. This is a very nice period correct tranny for a 1962-63 340 hp or 360 hp engine. Pictures of the newly aquired transmission and the write-up from the ad follow. 1962-63 Chevrolet and Corvette Borg Warner T-10 4 speed transmission. The input shaft 10 spline and has no rings. The 1st gear ratio is 2:20, 2nd is 1:66, 3rd is 1:31, and 4th is 1. There are no chipped, cracked or broken teeth. All the gears look new. All of the gear engagement teeth look excellent. The input shaft is 10 spline and the output shaft is 16 spline. The main case has a casting number T10-1C GM 3782212 and has 7/8 inch bore and is dated D-19-62. Assembly date WE292 (May 29th,1962).

The tailshaft has never been cracked, chipped or repaired, no heli-coils. All threads excellent. The input collar is casting T-10-6A with a diameter of 4.680 inches. The gear engagement teeth look excellent with little to almost no wear. There is wear on the syncros, they do not have a nice sharp point. I don't beleive this transmission has ever been rebuilt, the inside if the transmission is as clean as the outside and has never been blown up. I beleive this transmission still has all the original bolts from front to back and has all the matching numbers front to back! You just don't find them this nice anymore!This transmission turns, shifts, and feels real good. I have not personally run this transmission. I have owned this transmission the last 35 years that it's been in storage. I inspect each transmission as thoroughly as possible before offering them here on eBay. I have given the best and most honest description of this transmission that I could.
