Modern Driveline has the solution for you

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. 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 TK can’t handle.
So from small blocks to the latest boost feed LS, the TKX will make your Corvette a boulevard bruiser.

T-56 Magnum Double Overdrive Six-Speed
The centerpiece of TREMEC’s high-performance line-up, the Magnum 6-speed takes the state-of-the-art OEM technology and pairs it with the most popular flexibility features of the all-business TKX.
The result is a double-overdrive transmission that easily tolerates up to 700 lb-ft. of torque, delivers unbelievable sophistication, and that is far more flexible than any other 6-speed in the market.
Known in its OE form as the TR-6060, the Magnum is an aftermarket variant of the same transmission found in many of today’s most revered factory muscle cars; meaning refinement where you want it and strength where it counts!
Due to its brute strength, the Magnum is the largest Tremec transmission in the lineup. Being much larger than the stock four-speed, the tunnel needs to be enlarged.
MDL offers up a form-fitting fiberglass tunnel panel that is glassed into the body.
Available Gear Ratios
2.66, 1.78, 1.30, 1.00, 0.80, 0.63 OR .74, .50
2.97, 2.10, 1.46, 1.00, 0.80, 0.63 OR .74, .50
