Shifted into 4 wheel low

Shifted into 4 wheel low
I have a 2002 F150 4x4 Super Crew, that just recently had shifted into 4 wheel low while driving at about 40 mph. After the engine was turned off,then re-started it was ok. I have not driven it since then except for a drive down our road. The only way that it can be shifted into 4 wheel low is in neutral while the brake is applied. I'm afraid to drive it on the freeway. My dealership has never heard of this happening & was on no help except to bring in in. Any ideas? Could it just be a faulty selector switch? Any help would be appreciated.

?? When you put it in 4lo going 40mph, what happened? If you suddenly lurched forward, and the engine went from around 1500 rpms to over 5000 rpms, then you might have a problem...
If all that happened was the **** or lever went into that position, then all that happened was you shifted into 4hi and that was it...
It's correct that the ONLY way to go into 4lo is to be stopped, foot on brake and in neutral. If any ONE of those situations does not exist, then you won't go into 4lo...
When you drive it now, what are your rpms at? Does it drive normally? What happens when you do put it in 4lo (by being stopped, foot on brake and in N). Drive forward and does it feel any different? It should, if it's truly in 4lo.
I think you are fine... The whole process to put your truck in 4lo is setup that way so you CAN'T accidentally shift it to the position while in motion... Soccer moms and all! ha, ha!
Anyway, come back and answer some Q's and we'll tell you what the deal is..

Hello,
been a member for a while but never post, just read. However, the only way i can get my 01 f150 SC 4x4 is by putting the truck in "P" and turning the dial to 4lo. I know you can go to 4hi from "N", however, I just do it from "P". I still don't know why they call "On-the-Fly" when in it is not really on the fly.

You can shift into 4hi while moving no problem.. Well, you wouldn't want to do it going 60 mph.... Even with the floor shifted T cases, you can do this.. 4lo is the only thing that won't shift into unless you have the 3 elements in place...
More info from the OP is needed before any more help can be made...

i don't know. one time i switched into 4 wheel, turned the **** too far while in drive and i got a grinding noise. never had a problem with my 4wd, even used 4lo succesfully plenty after.
im just saying its possible to switch into 4lo without the necessary precautions but it's not good at all.
