Two years almost to the day, transmission going to sh*t yet again

[gilbert77]

They cleaned and tested all the valves in the valve body. But that was 15,000 miles ago. If I avoid any hills or heavy acceleration, it never slips. Keeping the RPMs under 2,000-2,500 you would never even know there was an issue.

Pretty sure the dealer service bulletin says to replace it with the drum.

That’s odd, my CDF was replaced but I don’t think the outer shell was not was the valve body replaced, just tested and cleaned.

Really don’t want to go in for another tear down as it’s a long time out of service.

Has a survey been done to see if the Ford ranger with the Extended transmission dipstick have the transmission issues verses those with not? It’s a closed system and wondering if the dipstick allows air into the system and thus?

The 10R80 transmission is vented and not a closed system.
