Changing the trans fluid
#1
#2
I did mine at 50K. Feel like it is somewhat cheap insurance for the truck. My transmission guy, who has always been very honest with us said that he has seen too many Ford tranny's needing more than a fluid & filter change if you wait to 100K. I have never had any transmission problems on any of our vehicles by doing the filter and fluid at 50K. I have heard that Ford has not been totally honest about some of their recommendations. I do like my F150 though.

I would do the trans service. There's no downside to doing it now. However, there could be a big downside if you decide to trust the 100k mark. As a mechanic for quite a few years I've done tons of trans services and there's no way I would go past 50k. Personally, every vehicle I have ever owned got a trans service every 30k whether it was a standard or automatic.

I think 60k is a great time to do a pan drop and new fluid.
Going 100k seldom presents any issues , from my experience anyway, but 60k is a great time to do a partial change. IMO, one of the biggest problems with the 6-10 speed transmissions is the amount of particulate matter created by all the shifting. As we know from our folks at the EPA: the solution to pollution is dilution. So even a partial change is very beneficial.
Do the filter if it lets you sleep better, but there is no need. The filter will outlast The transmission.

The newer transmissions have an internal thermostat which stops flow to the cooler until the trans is warm. So you will get a trickle of fluid, but in practice this wont work until the trans is hot enough to open the thermostat.
