  Make sure there are no trouble codes set in any system. After the repair and the transmission’s been refilled, brain-dead the system by disconnecting the battery or by removing the fuses. Then follow these steps for the relearn:

 

1. Make sure all electrical items (A/C, audio, rear window defogger, lights, etc.) are off.

 

2. Start the engine and hold it at fast idle with no load (in park or neutral) until the radiator cooling fan comes on, or until the engine coolant temperature reaches 194ºF (90ºC).

 

3. Let the engine return to idle for a minimum of five minutes with no loads (If the radiator fan cycles during this five minutes, add the length of time that the fan runs).    This procedure performs the PMC idle relearn on most Honda units. In some applications (remember, refer to factory procedures) you’ll need to allow the engine to run with the transmission in Drive until the fan cycles one time without the wheels moving,

then allow it to idle for five additional minutes.

 

On your initial test drive after the relearn, perform at least five, minimum throttle upshifts before becoming more aggressive with the throttle. Give it just enough throttle to allow the shifts to happen. Verify shift timing and pressures have been reset and you’re done.
