Auto Trans threw codes P0706, P0707, P1702

Tonight driving home, doing 70MPH my truck kinda stuttered and my wrench came on.
I have a Spartan Tuner and it shows the following codes
P0706 Transmission Range Sensor Circuit range performance
P0707 Transmission Range Sensor Low Circuit
P1702 Transmission Range Sensor Circuit intermittant

I noticed the "D" light was gone, however I had a few miles to go, but when I stopped at a stop light, started to go, it felt like I was in top gear, and it was slow to go, not slipping though.

I get home, turn it off, try to start it, nothing. I move the gear shifter a few times, turn the key on and off a few times, and the "gear light" came back on, moved it to park and it started up.

If it is a sensor, how hard is it to change? Can anyone lead me in the right direction?

Update..

I just drove it around the block, and it shifts fine until the codes pop up, I noticed the "gear light" went back and forth from "D to "R" several times, right before it threw the codes. Again when stop at a light and then go, it seems like its not in first gear. I am running the Spartan 210 Tow mode, but have not been towing anything.
Thanks
Jason

Mine did this occassionally, I would go into reverse from park and the truck wouldnt move, step on the pedal and it felt like the truck had a trans brake then it would suddenly move but studder. Wrench light would come on and then when you take off from a stop it felt like it was in 3rd gear. I wish I could help you, mine only did it mainly after highway driving or after mashing it to the floor then drive normal. I've heard the blame go to the torque converter or the shift solenoids. Mines in the shop for a new trans. I had an 89 Chevy Beretta GTU that would stick in overdrive all of the time until I wired an overdrive over-ride switch. Those were the days

I been doing some more research and I found it could also be a fan clutch. Someone had the same problems, but he listed a few more codes. MAN O MAN..

Ebay has a transmission Range Sensor for $100. Maybe try that first.. Think it is the cheaper route

Re: Auto Trans threw codes P0706, P0707, P1702

Mine just did this a minute ago. Scared the hell out of me. I shut it off and it wouldn't start for about 5 minutes. Then it did and wouldn't shift out of park. I moved my truck and now there is a puddle of fluid where it was sitting. I don't know what to do :s

Droppped it off at the doctors.. They said they believe it is the sensor inside the transmission. They said they should only have to drop the pan to swap it out. So parts, labor, replace trans filter and fluid.. $500.

I wont know until tomorrow with more details. Figured it would cost me $250 for parts, and filter, fliud. let them mess with it for $250...

Update...
Picked her up and no more problems. Basically $300 in parts, $200 in labor. That include, sensor, fluid, filter, and shop supplies(this one still cracks me up)
