Check Gage and Tow Haul light just came on

Was wondering if someone has had this issue, search the treads, but could not find it. Yesterday, I was driving and my check engine light came on and my tow haul light was flashing. When I tried to push my tow haul button on the shifter, nothing happened and it kept blinking, however is does go back and forth into tow/drive mode. My programer did not pick up any new codes. The truck drove the same and I did not notice anything different, except the annoying flashing light/s on my dash. My transmission read on my edge showed and negative temperature reading (very strange). If I shut off the truck and turn it back on...it goes off, but several miles later, it does it again (lights come on and temp is messed up). If I put it in park everything goes to normal.

I'm pretty sure it is my transmission sending unit sensor. I have no idea where it is located to check on it. How hard is it to replace? Really don't want to go to the dealer since I just spent a fortune on my boat's service and would rather do it myself if I could.

Any suggestions would be beneficial since I am 5 hours from my house with my truck and need to drive home. Don't want stall in the middle of the desert.

It's the sending unit in the transmission. Mine went out a while ago and my mech. Gauge read normal but the temp gauge on my sct read negatuve just like your edge. I haven't fixed mine yet but I've been told it's like a 75 dollar part and you need to drop your trans pan. And while your in there you might as well change the filter on the inside and outside and throw in fluid. So it will be around 200 or more total

I assume no problems with driving on it for a while. It's time for a trans service anyways, so that's good news. I was a little nervous it might be something bigger.

Thanks!
