I have an 05 f150 with the 5.4L engine. My issue is, in 2wd the truck acts like it's in neutral, but I'm able to shift through all gears. While in 4wd the truck runs normal. I'm stumped on what the problem is. I have checked and replaced fuse 33 shift solenoid and fuse 16 brake shift solenoid. It seems like an electrical problem but I'm not sure, what ideas do you all have?

 

So in 2wd it won't move at all just rev in 1st, 2nd, and drive but if you put it in 4x4 it'll drive around is this what you're saying just trying to clarify your post

 

Year, engine...

 

Oh come on martian lol

 

Yes that is correct

 

Stupid obvious question here but is there a rear driveshaft

 

Yes

 

Does it spin when in gear in 2wd when you push the pedal

 

I was driving it home from work one day dropped off my buddy went to start it back up and then it happened.

 

The drive shafts does not spin in 2wd when giving it gas
