Hey guys I'm new here and I have a bit of a problem.
Yesterday when leaving work i started down the road and noticed my speedo wasnt working and my truck wasnt shifting out of 1st
I shut if off and started it again and it worked just fine. Ever sense then it will sometimes work when i first start it and sometimes not
Once today it just happened while i was still driving down the road.
It seems like when i put it in park and then back to drive it starts working again?
So essentially sometimes but not everytime this happens but its obviously not completely broken because it fixes itself?
Anyone have any idea what might be wrong?
I did go thru some standing water that was deeper than i thought a few days ago so maybe a sensor got wet?
Any feedback would be much appreciated :D

Ok, so I thought I had fixed it because it hadn't acted up for a couple days but today it happened twice..
Does anyone know which sensor monitors your speed and sends that information to your speedometer? What its called and where its located would be a huge help.
It obviously is just bugging out a bit because it works most of the time.
Thanks again

Edit: Would probably help to mention its a 2007.5 5.3
