Name: Manual shift microcontroller Size: 17cm x 9cm x 7cm (6.7in x 3.5in x 2.8in) (LxWxH) Weight: 200g (7.1 oz) Operation: Functions like a full manual valve body; whichever gear is selected, the transmission will remain in that gear. Gear changes made with factory column shifter or floor-mounted shifter. Shifter must have 7 positions: PRND321. Transmission will not shift up or down without moving the shifter. Maintains forward shift pattern and engine braking on downshifts. Operates with continuous full line pressure for shifts, reducing clutch slippage and maintaining cooler operating temperatures. Torque converter lockup with included switch and indicator light.
