It can't hurt to do it. Disconnect for about 10 minutes would be enough.

There is a procedure to make it learn faster, but it isn't necessary. Just drive it.

drove this morning. seemed like everything was ok. drove about 15-20 miles, slowed to make a turn, came out of the turn gave it throttle and slip. then the gears engage. after-wards i noticed no overdrive gear. dont recall this happening before. while driving i put the trans to neutral. killed the motor while coasting and restarted. got overdrive back. disconnected the batteries once back to the shop to try again. still slips once and a while. didnt loose overdrive though.
