By the time you bought the equipment and learned how to use it you will have spent a lot more than the 65.00 for a new switch. Some things are not worth diagnosing.

Oh yeah. I just had to move it too clear the snow out of the driveway. Reverse still works good. The truck feels like its trying to creep forward in drive and then lets go at about 1800 rpm. I tried locking it in gear with efi live and it did the same thing. I brought up PID PNRD Gear Selector and it says unknown in everything from park to 1. PID PRNDSW-TFPSW stays at D2 and
PID PNRDSW-PNPSW stays at INGEAR. Would this point to a failed NSBU?
It would be limping, he said it is not. He also says reverse works good, which correct me if I'm wrong, but I think that c1 and c5.
It has been limped but, probably in 5th. Very rare to limp 1st and not lose forward alltogether. Why was he able to pull into driveway in 4H if C1's are gone?
I will take your bet and raise you.

I knew I screwed that one up
. All I'm saying is his c1's or clutches for that matter, aren;t so bunrt up the trans wont move, because he said he drove up to his driveway. How could he have drove in 4 hi just fine? then switch to 2hi and all of sudden his trans wont get him up the drive. Also it would be limping, he says its not limping and no CEL. So something else screwy is going on.
I finally got a chance to pull the main harness connector and it does the same thing. And now when i try it, it doesn't even feel like its grabbing at all. It wont even hold the truck on a slope and it would right after it happened.
you saw mine... i drove through the clutches and TC and didnt limp... some times it would other times it wouldnt. on my stocker.
