- The Tork Master 2400 fits 1984-93 GM 700R4/4L60 w/30 spline input, 1993-1996 4L60E w/30 spline input and 1997-04 Corvette transmissions. This converter retains the lock-up feature. Dont let the exceptional value fool you into thinking Tork Master Converters are not packed with lots of quality features, making them the best value-priced street performance converters money can buy. These converters perform best when paired with stock to modified engines up to 350hp/350 ft lbs. of torque, and lighter weight applications, like street rods. The Tork Master will provide noticeably quicker launches and harder acceleration while maintaining normal daily driving qualities. Upgrades like a new precision alloy steel pump drive tube, needle thrust bearing when factory equipped, new thrust washer between turbine and cover when required, and pressure tested and fully balanced by expertly trained technicians. Notes: Higher stall converters can generate more heat, so we highly recommend adding a transmission cooler. Not recommended for big block, supercharged, plate-type nitrous oxide or trans-brake applications.

- The SportShifter is a great value with the performance look of the MegaShifter, but without the ratcheting function. This detent shifter is our easiest shifter to operate and functions like most OEM shifters, with no positive stops between gears or a reverse lockout feature. To shift out of Park, you simply lift the handle and pull it back into Reverse, then simply move the shifter rearward to forward gears. To shift back into Reverse, from Neutral you will need to lift the handle and move shifter forward and again lift the handle to move it into the Park position. Features include a textured black mini console that has a chrome top plate with an illuminated gear indicator. Other features include a polished aluminum shift stick with a black T-handle knob and an accordion boot reminiscent of a manual 4-speed, giving your vehicles interior that classic muscle car look. The shifter includes a lighted gear position indicator in the bezel, a micro-switch for back-up lights and a neutral safety switch preventing accidental starts when in gear. Includes a 5-foot long performance shift cable, cable brackets, transmission levers, all hardware and detailed instructions for an easy installation you can do at home. Compatible with all 1966-later Chrysler A727, A904, A518. Ford C4, C6, AOD, AODE, 4R70W, E40D, 4R100. GM TH350, TH400, 700R4, 200R4, 4L60, 4L60E - 4L85E transmissions (w/o PRNDL switch.) Notes: Ford AOD requires installation kit #40496, AODE and 4R70W requires installation #40504, E40D and 4R100 requires installation kit #40505. GM 4L60E - 4L85E transmissions with PRNDL switch will require cable bracket #70499. Caution: Like OEM shifters, the Sport Shifter does not have a positive reverse lockout feature and without care, it is possible to accidentally over shift into reverse gear while moving.
