If you need ideas, follow my build

our trucks started out nearly identical

...or Bluex, his looked a lot like yours too.

Very nice find- especially from Iowa! (I think I already said that, but it is a point worth stressing)

So your truck is on 33" tires with a 4" lift? am i correct or please correct me if i am wrong! looking to buy tires SOON and i want to know what to get! I have 2" of lift

285/75/16 (same thing as 33") on 16 X 11 rims

3" body lift, zero crank or anything else

OK so i am having problems already! When started, everything is fine. No lights come on that shouldnt be on. When i go to drive a lot of the time, the speedo will NOT work and i will have only 1st and 2nd gear with the ABS light on and no ABS. This normally comes and goes usually when i start the truck and drive for the first 2 minutes. But tonight, it was doing this and then the speedo kicked in and it defaulted to 3rd gear with only Park, Reverse, nuetral, and 3rd working properly. Drive, 2nd, and 1st were all defaulted to 3rd gear. I pulled over, shut the truck off completely and waited 30 seconds. Started it up and it drive like normal... Please HELP! When i first bought it it threw 3 codes, which i cleared and now dont remember.. Stupid me.. I feel as if it could maybe be the speed sensors? but i do not know. Like i said, please help. Thank you

Sounds like the VSS sensor in the tail shaft of the transmission to me...

Help me out, that does what and how hard is it to replace?? Im not real used to the whole electronics thing.. lol
Thank you for the info

Its what controls the speedometer. It stands for vehicle speed sensor. Without it the Speedo doesn't work, neither will the abs since it uses that to know how fast the rear tires are going. Last but not least the pcm uses that information to know when to shift the transmission.

I would check all the wiring first before replacing anything....

Hopefully! Just be sure to check all the wiring for nicks, binding, or looseness- especially at the connections.

Well..... I got it stuck last night... I was cruising along in the field and then i found a waterway... Wouldve been over the tires had it not bottomed out... Tried with one truck to pull it out, no luck. Then we tried with two trucks, still no luck.. So we had to use the tractor! Dont plan on getting it stuck like that again...
