I've done hydraulic flushes and used hydraulic "fluid exchange" systems the size of a car to flush the hydraulic systems on aircraft worth more than the real estate of a middle class neighborhood while making a bit over $40 an hour. That's all cleaned and tested like a hospital surgery center.
With cars/trucks...
It's all about how clean the machine is and how competent the tech is.
Doing the trans bulkhead o-rings, valve body to trans-o-rings, fluid, filter flush to include the new cooler and T-case change at home is all going to be WAY less than a dealer fluid exchange.
If I had a newer raptor out of warranty at 50k miles I'd just go to Galpin ford not dumb f*ck Egypt ford and get a fluid exchange.
Don't follow Ford's recommendations. Do it more often if you are a wheeler, not a poser.
The title on this one is sarcasm.
I'd do the seals and a OEM thermal valve not the thermal bypass if it gets cold where you are on this one.
The bulkhead connector. They have a new sleeve part number with new o-rings now since this.
