Hello guys, first post here so forgive me for any mistake I may make. I just recently purchased a 21 F150XLT 2.7 FX4 off-road package. I heard the 10 speed transmission on these truck is pretty iffy and was wondering what steps I can take in order to maintain the truck and take care of it so it lasts as long as possible. Same goes for diff and other fluids. Can anyone give me a rough guideline on when I should be doing these things to let the truck last as long as possible. Trucks driven 74k km’s btw.

 

Welcome to the forum.

 

I would follow the maintenance schedule spelled out in your owner's manual.
