so here we go with the problems... when i put my truck in drive it doesn't show that I'm in drive and shifts fine but will not lock-up no od...any suggestion?

 

fill out your sig so we know what you drive, what mods ya have, some programmers will disable that on higher levels.

 

totally stock

 

Maybe shifter cable, but more than likely deeper in the tranny if its not shifting into OD.

 

If its not seeing drive then it won't shift into OD. The current gear is monitored by the range selector box on trans wher ethere used be a neutral safety switch.

It could be an adjustment there, a bad box, or a shift cable adjustment.

Do the rest of the gears light up when your in them?

Can you move the shifter to get D to light?

 

You may want to try lightly tapping on the bracket under the truck that holds your shift cable. A rock may have hit it and knocked it out of whack. I forget which way you need to tap it but just do light taps as it is VERY sensitive and only needs to move a tiny bit...

 

the only gear that lights up is park and neutral that's it, and i only have second and third gear.

 

disconnect the battery cables for 15 or so minutes and maybe it will reset. also go under the truck and unplug the electrical connectors to see if there is corrosion in them. i had a problem with one of mine

 

well I guess it's going to the trans shop tomorrow because nothing I've done has worked.. i guess we'll see what they say. thanks for all your help, when i have news as to what it is I'll let you all know.

 

ya i kinda hate the shifter lever. i really gotaa jiggle it so it clicks into park, and doesnt HOOONK because it thinks its still in Reverse when i get outa the truck

 

so it's been over a week, and two trips to the tranny shop.you see my problem is also intermittent. so of coarse the first trip going to the doctor it's running fine and throws no codes and was told if it's not acting up i cant diagnoase...truck ran fine for another week. then starts to do it's crap again on Saturday. back at shop still screwing up and he hooks his reader up to it and says that's odd i can't reed your tranny trys ten times.he finally says leave it here and I'll get to the bottom of this. he called today and says that he thinks the ignition switch is bad and is not sending enough current to the tranny to tell that the truck is even running... sound like it could be logical? what's your two cents.. and my tranny guy is known for building some of the most bullet proof 727's so i don't think he's just trying anything..

 

Since some f them work I would guess the circuit is good. The range selector box is a high probability problem but with electronis its tough to rule out other things.

 

well the ignition switch didn't help nor did the range selector box... i give up..any other thoughts?

 

Woops, you have an 03. Did you ever have the TSB done for the connections on the ECU not sealing and causing corrosion in the A and B connectors?

 

duno i've only had the truck for 2 weeks.
