SOURCE: auto trans shifting VERY HARD, possible cause?

It could be several things but I will give you a few ideas anyways to try and avoid the costly Ford dealer mechanics. Check your transmission fluid to make sure that it is full and that is still good and red. You may also want to just go ahead and change your transmission fluid but when you do so remove your transmission pan. Inside your transmission pan is your automatic transmission fluid filter screen. Make sure to clean it thoroughly and put back on filling the transmission with new fluid. Cleaning the screen is probably the most likely thing that will help. You also might want to consider using a transmission fluid additive that will help it shift easier. I've had pretty good luck with Lucas's products. Hope this helps. Be sure to let me know how it goes and if you need more help clarifying. Goodluck.

SOURCE: Is the module and/or solenoids

The transmission control module is part of the engine controller in the firewall behind left fenderwell.There is a solenoid block inside the Transmission pan that contains 5 solenoids , 2 shift,1 coast , 1 tcc and 1 pressure control.Various engine sensors also input into the transmission controller such as TPS ( throttle position sensor ) , map/mass ( engine load ) , and engine rpm.Also there is a trans temp sensor built into solenoid block and a range sensor on the side of trans that tells the computer where there gear selector is.Vehicle speed sensor also inputs into transmission controller.It takes a lot of data to decide what gear the transmission should be in.
