MCU-0806 rev2 Controller Package
This controller package includes the MCU-0806 controller, the 2 1/16" round Digital readout that indicates your selected gear, Line Pressure, TCC Lock-up status and the wiring harness. It will give manual shift operation to all of the GM 4 speed computer controlled transmissions. No programming required it is programmed for your particular transmission before it leaves the factory. This is a great solution for adding a overdrive transmission to an older car or truck. Great for Drag racing, Street cars or Hot Rods!

Putting a 4L80E in your truck is easy with this unit. It will give you full manual shifting like a manual valvebody but without doing any modifications to the transmission. You simply connect it to the factory connector at the transmission. It gives full manual control over the Torque Converter Lockup - Lock or Unlock as needed in 2nd, 3rd or 4th gear. It gives full control over line/shift pressure which can be controlled with either a standard 1Bar GM MAP or a GM Throttle Position Sensor, but it also has a manual adjustment knob to fine tune the shift pressure on the fly. (Requires a paddle or ratchet shift switch and a transmission pigtail which are not included.)
