With the vehicle stopped and the brake pedal depressed, move the shift lever from P to N to R and back, stopping for three to five seconds in each gear.With the vehicle stopped and the brake pedal depressed, move the shift lever from P to N to D and back, stopping for three to five seconds in each gear. Perform several forced downshifts (5-3, 5-2 and 3-1) at medium to large throttle openings.Perform several sequential forced downshifts (5-4, 4-3, 3-2 and 2-1) at small to medium throttle openings.If additional adaptation is needed, perform the following additional steps: Note: Hold the accelerator pedal steady during all the upshifts.Once the transmission fluid reaches the minimum parameter, accelerate from a stop at the specified TPS percentage, allowing the transmission to shift through all the gears, and then slowly decelerate to a stop.Attach a scan tool to the vehicle to monitor the TPS percentage and transmission-fluid temperature to ensure that the conditions for relearning are met ( Figure 2).After the shift-adapt values have been cleared, the adaptive learn procedure must be completed as described below.The chart in Figure 2 shows the TPS and transmission-temperature ranges for each Hyundai vehicle. After a few minutes, you can start the car and the transmission will be reset. Next, use a jumper wire to bridge terminals A and B on the TCM connector for 10 seconds while counting down from 30. First, make sure that the vehicle’s battery is disconnected and that all power sources have been turned off. Turn off the ignition, then release the pedal. How Do I Manually Reset My Tcm If you need to manually reset your TCM, the process is fairly simple. Some vehicles have a very narrow TPS window and others have a narrow transmission-temperature range that must be adhered to. To reset the Nissan CVT transmission control module, turn the ignition to the On position and press on the gas pedal for about five seconds or until you hear a clicking sound. One way is by disconnecting the battery cable for 2 to 3 minutes and waiting to see if the check engine light comes back on upon reconnecting the battery and start the car. There are a few ways to reset your Engine control modules. Looking for more technical transmission info like this?

Before replacing any parts you want to reset your ECM to ensure that part replacements are absolutely necessary.
