Review GM T56 2nd Gear 43t 2.66 Oem fits CORVETTE GTO 1997–2007

The GM 1386-082-006 97 07 Corvette T56 2nd gear 43T 2.66 GTO is a high-performance replacement gear for the T56 Magnum six-speed manual transmission found in various Chevrolet and Pontiac models, including the Corvette and GTO.

This gear is specifically designed for the 2nd position, also known as the overdrive gear, which is used to reduce engine RPMs at cruising speeds, resulting in improved fuel economy and a more comfortable driving experience. The gear ratio for this 2nd gear is 2.66:1, which is relatively long compared to other gears in the T56 transmission.

The 43T designation indicates that this gear is a 43-tooth unit, which is larger than the standard 39-tooth 2nd gear. The larger tooth count allows for a lower RPM output from the engine for a given vehicle speed, resulting in quieter operation and reduced engine wear.

This gear is manufactured by General Motors using high-strength steel and advanced heat-treating processes to ensure durability and longevity. It is precision machined to tight tolerances to ensure proper engagement with the other gears in the transmission.

Installing this gear in your T56 transmission is a straightforward process that can be done by a skilled mechanic or a dedicated home mechanic with the proper tools and experience. It is recommended to follow the instructions in the transmission service manual and to use new synchronizers and other transmission components as needed to ensure proper function and longevity of the transmission.

In summary, the GM 1386-082-006 97 07 Corvette T56 2nd gear 43T 2.66 GTO is a high-quality, durable replacement gear for the T56 transmission that offers improved fuel economy, quieter operation, and reduced engine wear. It is specifically designed for the 2nd gear position and has a tooth count of 43 and a gear ratio of 2.66:1. It is manufactured using high-strength steel and advanced heat-treating processes to ensure durability and longevity. Installing this gear involves following the instructions in the transmission service manual and using new synchronizers and other transmission components as needed.
