Keisler's T45RS-425 is for the budget-minded enthusiast that doesn't require the extra strength of the TKO. Keisler's exclusive custom-designed front cover allows the transmission to bolt directly up to a traditional GM or Ford removeable bellhousing. Mopar applications will require a Keisler bellhousing, or we can modify your existing Mopar bellhousing to accept the T45RS-425.

Optional Keisler ClassicFit™ Offset Shifter is also now available! It provides the same correct shift lever attachment point as our TKO PerfectFit™ series. Modification of the 4-speed shifter hole is required for some applications. (Note: If you desire minor or no modification, please see our TKO PerfectFit™ series of transmission systems).

Enjoy low-rpm cruising, great fuel economy, and less engine wear with the Keisler T45RS-425 5-speed overdrive!

Keisler-exclusive Super Duty 26 spline input shaft for added strength.
Custom billet aluminum short-throw shifter designed to provide better-than-stock shifting.
Shifter stub is on-center at 20-1/2" from the rear face of the bellhousing. Optional Keisler ClassicFit™ Offset Shifter mechanism is also available, to duplicate the factory shift position in most popular musclecars!
Choice of electronic or mechanical speedometer output.
High strength 31 spline Ford pattern output shaft.
Includes Keisler's permanent fix (Patent Pending) for the T45 chronic reverse shifting problems - No more jumping out of reverse, gear clash, or grinding.
Gear Ratios: 3.37 1st, 1.99 2nd, 1.33 3rd, 1.00 4th, .67 5th; 3.22 reverse.
Low RPM Cruising - 33% drop in engine RPM in 5th gear (check out our Speed Analyzer).

Nation-Wide Parts & Service - Parts in-stock; service in-house.
NOTE: This transmission is not a direct bolt-in, and will require modification to your driveshaft, crossmember, and possibly your transmission tunnel.
