2015 Transmission issues
The 6F35 transmission in the XLT is not happy at 190,000+ miles. I'm getting the shudder despite the shifts remaining fairly smooth. How many people have had success replacing the trans fluid and adding the transfix goop? I understand that you can only drain about half the fluid with a change. Should I try multiple changes to flush even more of the old fluid out before adding the transfix?
Hate to dump the Explorer after dropping $2K to replace the water pump and chain components...other than the pump and this recent shudder, the Explorer has been a bulletproof champ.
