How do you change an overdrive band in an aod transmission?

To change an overdrive band in an AOD (Automatic Overdrive) transmission, first, remove the transmission from the vehicle and drain the fluid. Next, disassemble the transmission case to access the overdrive unit, which typically involves removing the valve body and the rear cover. Once exposed, replace the worn band with a new one, ensuring proper alignment and adjustment. Finally, reassemble the transmission, refill it with fluid, and reinstall it in the vehicle.
