Hi, I am new to the forum and I'm looking for help for a transmission problem in my son's 2001 Accord. When it is cold, the transmission slips sometimes from 1st to 2nd gear. It is very inconsistent and sometimes it doesnt slip at all. We checked codes and we are getting P0730 incorrect gear ratio and P0780 shift error. The car is a 4 cylinder with 188,000 miles. Any suggestions. Someone told me it could be the TCM module.
