The Borg Warner T-100 WT266-16B transmission is a classic automatic transmission that was originally used in Chevrolet vehicles between the years 1958 and 1963. This transmission is a 2 or 3-speed automatic unit, designed to provide smooth and efficient power transfer from the engine to the drivetrain.

It is made of high-quality materials, including heavy-duty gears and robust clutch packs, which can handle high horsepower and torque applications. The transmission also features a robust cooling system, which includes a large radiator and multiple transmission coolers, to help maintain optimal operating temperatures.

When rebuilding or installing this transmission, it is important to use high-quality replacement parts and follow the proper installation procedures to ensure reliable and trouble-free operation. The transmission requires regular maintenance, including fluid changes and filter replacements, to keep it running at its best.

Overall, the Borg Warner T-100 WT266-16B transmission is a versatile and reliable unit that is well-suited for use in classic Chevrolet vehicles. Its robust design, smooth operation, and wide compatibility with different engine sizes make it a popular choice among enthusiasts and restorers.
