NCR Controller: This transmission kit functions similarly to a full manual valve body, with the gear you select being the gear the transmission is in. You can change gears using your factory column shifter or floor mounted shifter, but it must have 7 positions labeled PRND321. The transmission will only shift up or down when you move the shifter. It maintains the OEM forward shift pattern and engine braking on downshifts, and operates with continuous full line pressure for firmer shifts, less clutch slippage, and cooler operating temperatures. It also includes a torque converter lock up switch and indicator light. Manufacturer Part Number: 4L60e Package Includes: 1*4L60e replacement kit
