The Keisler ClassicFit" Kit is the most economical way to put a high strength, modern overdrive Tremec transmission in your vehicle. Our ClassicFit" Kits contain all the same high-quality components as our PerfectFit systems, but with an unmodified transmission. Enjoy an overdrive manual transmission system with low RPM cruising, and great fuel economy today.

NEW! Keisler ClassicFit™ Offset Shifter is now available! It provides the same correct shift lever attachment point as our premium PerfectFit™ series, but in a lower cost "bolt on" package. Modification of the 4-speed shifter hole is required for some applications. (Note: If you desire a no-cut, bolt-in kit, please see our PerfectFit™ series of transmission systems).

NEW! T45RS kits are available! Rated from 350 to 425 lb.-ft., these kits are ideal for the enthusiast on a budget who doesn't need the extra strength of the TKO.
