Sonnax Externally Adjustable Low/Reverse Servo Kits
Sonnax externally adjustable low/reverse servo kits make band maintenance quick and easy. They offer an ideal way to improve reliability and make staging more consistent and predictable. Checking L/R band adjustment after repeated use is good practice. Unfortunately, OE servos with steel covers are difficult to adjust in a vehicle, so a quick check with such a servo installed is impractical for most racers. Sonnax externally adjustable servos provides an improved design that makes checks and adjustment of the L/R servo easy. There is no cover or access plug to remove because the adjuster itself extends through the cover. A quick check is done simply by pushing on the end of the adjuster and observing the movement of the piston relative to the servo cover. Select the kit designed for your transmission. Features: * Quickly check and adjust the low/reverse band to prevent trans-brake malfunction * Unique servo cover and adjuster design makes in-vehicle band service easy * Works with or without OE 1-2 accumulator piston Included: * 6061 Anodized billet aluminum cover * Piston * Pin * Jam nut * Cover seals -- Two PTFE, one extra * Piston seal * Cover O-ring * Pin O-ring Kit for TH400 will also include: * Cover flange O-ring * Bolts (6) * Washers (6)

Barton Dodge Challenger Shifters
For the spirited driver, a Barton Dodge Challenger shifter is a must-have. They're beefier, more solid units—from the throw-rod, all the way to where the shift knob or pistol grip starts. With their 44 percent throw reduction, you experience positive, notchy shifting, preventing missed gears or gear engagement. Full isolation of the handle from the shifter makes them quieter; and self-centering springs aid the yoke and linkage back into alignment with the selector rod. Barton has these shifters available in the full system with a variety of finishes/colors and knob or grip choices, as well as the shifter only for use with the OEM handle and knob.
