Ford Transmission

[ct78barnes]

I have a 2011 Ford 22,500 chassie and 25,000 miles on it and was wondering about getting the oil changed. We have a big Ford dealer near by so I would have them do the oil change on the Transmission. After 5 years all towing our 4,500 pound Toad would it be a good idea to have it changed. I think Ford says every 40,000 miles but how about the years it would take me to reach 40,000 or 45,000 miles on the coach. What do you experts have to say . Thanks

If you are going to have it done, tell them to just drop the pan, change the filter and gasket, if necessary. Refill with genuine MOTORCRAFT transmission fluid.

I know this only gets about 50% of the fluid, but with that few miles and time it is not worth the extra effort or cost.


(I have an E150 with the same transmission. 130k and still on the original ATF !)

I would use a transmission shop before a dealer.
I would have them drop the pan and change the filter.
I would suggest that they blow out the cooler lines.
I service mine closer to 15,000 miles. You should consider using the specifications for severe duty.

I agree, nay to the flushing. Go with a drain/refill. If it just takes Dextron go with Dextron VI as it is fantastic fluid. Brand doesn't matter (think walmart supertech) so long as it meets the Dextron VI standards. (note this is 6 (VI) not 4 (IV)). Get a new filter, drain, clean, install filter, replace fluid... See you out there.

I am with you on the "flushing", even though that is what most all dealers and "service point's" will do is "flush"...

It is not hard to do it yourself although the tranny holds quite a few quarts, and it can be a little messy on the driveway.
You can get that last quart out by removing the dust pan off the bottom of the tranny, and using a large blade screw driver, turn the transmission fly wheel and the last last quart will come out of the torque converter.
I just don't don't trust dealers...When they pay their employees $7 to $8 dollars an hour, you get what you pay for.........

Draining and replacing is OK, but don't like flushing and especially with older units, that may have never been done before.
Our last coach had over 90K on it and after quite a few mountain trips, pulling a toad that was a ton too heavy for it, I just drained out the 4 or 5 qts, that I could and replaced that a few times over a month's period of running it.

this would be about the right time, as I have my E4OD serviced every five years, and for the same reasons.

For the minimal amount that it would cost, do it for your own piece of mind and continue to enjoy your coach.
