Thanks for the info.....Hot Flush.
I always understood Ford recommended to never add anything to the 6R140 transmission except Mercon LV...... No friction modifier... No additives ?
I could have sworn Ford required a friction modifier additive during a trans fluid change. I don't have access to the service manual, but check with a dealer.

To "properly" flush and replace the 17 qts of fluid, a hot flush is required.

Can you change the fluid in this tranny DIY like you could the old 5R by draining the pan then disconnecting the cooler lines, starting the truck and drain and fill at the same time to remove the rest of the fluid as it fills with new ? I hear there is a thermostat in the 6R and you need to hot flush it ? Any info ?
