TKX Five-speed Overdrive
Are you looking for an extra gear in your Corvette?
Modern Driveline has the solution for you
Tremec TKX single 5-speed
With either 18% or 36% overdrive.
MDL Corvette Specialty designed & engineered
Side Shift TKX.
Our Corvette TKX five-speed has been customized to fit in place of the Muncie four-speed. With fresh stock body mounts, the TKX will clear the tunnel.
MDL’s side-mounted low-profile shifter places the lever in the stock location.
Unlike many other shifters of its kind, our shifter has the lowest profile that is rock-solidly mounted.
The shifter linkage remains enclosed keeping dirt out and allowing the oil to remain in the shift box.
The shifting quality is short and confident.
Corvette equipped with an M21 rock crusher the TKX will slip right in.
If not, we offer a complete line of 26 spline clutch sets for both Mechanical and hydraulic clutch releases.
At 600lb-ft of tire-melting torque capacity, there is not much this TKX can’t handle.
So from small blocks to the latest boost feed LS, the TKX will make your Corvette a boulevard bruiser.
