Take manual control over the AW4 automatic transmission in your Jeep Cherokee. I am not sure if this will work on 97+ Cherokees, but I do know it will work on 96 and older. I had it in my 92 Cherokee. You can place the trans in auto mode, or manually select your gear. There is also a switch to control the torque converter lockup. All you need to do is splice some wires and mount the switch. Instructions are included.

Must pick up in Grand Junction. $75
