Manual shift control for your Supra's automatic transmission. Ever dreamed that you had one of those trick "manual" autos that are offered in some new cars? That day is here. SupraStick is an exclusive new piggyback computer that allows you, on the fly, to take complete control of your transmission. Features: On the fly selection of "normal automatic" mode and "SupraStick manual shifting" mode - Seamlessly switch at any time in any gear between auto and manual modes. Complete control over the shifting of the car - any gear can be taken to redline, and shifts may be initiated at any time. Automatic torque convertor control - Torque converter will automatically lockup in all 4 gears under the proper load, vice a limited lockup in 3 gears with the stock system, and no lockup when manually shifting the p-n-2-l lever. Automatic protection from downshifting into a gear that will redline the engine. (This is the only limitation imposed, and is removable if so desired.) Fully programable to adjust shift firmness, rpm downshift limits, and other options Shifting is accomplished by either the steering wheel cruise control paddle (if so equipped) or your own upshift and downshift buttons / paddles that are mountable wherever you want to put them.
