My last truck was a '68 F-150. It was manual shift with manual four wheel drive selector on the floor. Hence, operation was very simple. The 2015 F-350 XLT I just acquired is an automatic (first ever in 71 years!) and I do not understand how to operate the four wheel drive function. The vehicle has the 6.2 gas engine, 4.30 gearing, Electronic Shift On the Fly, and Electronic Locking Rear Axle. I read the manual and researched on the internet just how to drive in FWD low but am still not sure. The manual says to slow way down, or stop; then shift the transmission into neutral. Following all that, it says to select FWD low on dashboard mounted switch. Am I supposed to leave transmission in neutral?? To me, the truck would not move with the transmission in neutral. I did not try anything for fear of messing something up (I do know that I must not be on hard surfaces when in FWD, or with rear axle locked). Can someone please enlighten me?! Thank you much. BTW... does FWD function in reverse??

 

put the truck in park or nutral then shift the 4 wheel dr switch and then in too reverv back up about 6 ft and put into dr and u should be good to go
