68RFE Relearn Process

If your 2010+ Ram is equipped with the 68RFE automatic
transmission, you must perform a re-learn procedure each time
the ECM is flashed, even if you aren’t loading transmission

Failure to do so will cause premature transmission
failure. To perform the procedure after the ECM is flashed, drive
the truck and apply no more than 30% throttle for at least 100miles.   

It is important that the transmission shifts up and
down as much as possible during this period. NOTE: The 100
miles is to re-establish the CVI values.

It is common for these
transmissions to take 400-500 miles or more to settle
down. Sustained highway speeds should be avoided for the first
25-30 miles.

If you purchased a tuned TCM for your 2007.5-
2009 68RFE equipped Ram, you must perform the same relearn
process upon installation of the TCM.
