Used TCM Need Reprogramming or Not?
I bought a used transmission control module which I plan to install in my 2004 Coupe. The used TCM I bought is also from a 2004 Coupe. Does this TCM need reprogramming before it will work? I've been through all the threads on the TCM and there are both "yes" and "no" answers. It seems to work without programming for some and not for others. Can someone straighten this out? Also, my factory manual says there is a "Quick Learn" procedure that requires a special scan tool. However, does the term "Quick Learn" mean that the there is also a "slow learn" procedure that doesn't require the scan tool, but just a certain number of driving cycles?
