I was considering replacing the transmission pan in my 2012 (currently less than 10 000 km on it) with one from "Performance Automatic".....it holds I believe one quart extra and comes with a dipstick/tube.
The transmission does not have to be serviced for some ridiculous amount of kilometres as far as I am concerned (after the warranty period) according to Ford. Although many would say it would be a waste of money by doing the filter/fluid change two or three times before the first suggested interval, I would prefer to do so. You will always get someone who goes a considerable amount of km/miles without changing transmission fluid and never has a problem. I just think that 15 or 17 litres of the same lubricant in a system for that period of time is a gamble.
I emailed Ford, inquring about changing the pan, and their response was basically.....replace any factory parts and the warranty is void (for that component). I believe it was more to the effect that if the problem was a result of the replacement part, then you are out of luck.
I can pretty well guarantee you that Ford (or any other manufacturer) would say that any transmission problems encountered was due to the replaced pan...even if the level was correct and the correct fluid was used.
I wouldn't hesitate to say that 70 to 80% of a dealers money is made by the service department. Why recommend replacing fluid more regularly (even though they make maybe $100 a pop) when they can make thousands on a repair/replacement?
Sorry for sounding so cynical....must be the two hours of sleep between my nighshifts.
