4x4 mode question
I see some f150s have 2w/4h/4l. Others have an extra spot that is 4A. Is this something specific with the transfer case or is it controlled by a module.
If it wasn’t mechanical with the transfer case, could the switch be replaced and use forscan to make the changes. Just wondering. |
it's a different transfer case.
|
Thanks for the answer. I kind of thought so but I wanted to make sure.

Been posted before but here is a video explaining the torque on demand transfer case.

Awesome.

Ford should make the 4A system the standard 4x4 system. Then upgrade the higher trim levels to a full time AWD 4x4 system with a locking front and rear differentials.

Then you missed the benefits mentioned in the video I posted. I much prefer the TOD over full time AWD...wife is on her 2nd durango with AWD and I still like mine better.

What the video didn't say was that TOD systems require wheel slip before engaging 4WD. TOD systems are basically a part time system that can engage 4WD for you when needed. This is why you still have to put it in 4H if you go off road. Full time 4WD is always on and engaged. You only need to select 4LO if you need it. If Ford really wanted to upgrade they could skip the locking diffs and go with full time 4WD with torque vectoring differentials. Then the system could transfer power rear to front and side to side. There is a reason Range Rover and Toyota Land Cruisers use full time 4WD. And as for cost, a Limited is already pushing 70 grand so cost is not a factor.
4A=AWD full time 4H=4wd no slip The TOD has all the modes vs the durango AWD where you have AWD and 4L with no 4H. |
