What kind of vehicle is this year make model and engine size?
also, the vehicle isn't cranking?
2003 chevy 2500 hd with 6.0 auto, the gear indicator light shows to be in second gear all the time. engine will not crank. removed and bench tested starter, tested good. the back up lights will not work either
If you replace the TR switch already and it's adjusted correctly you will need to see a dealer for a pcm reflash.
There is a TSB on this issue.
so there is nothing i can do to fix it? have to haul it to the dealer?
Well, since you replaced the TR switch (that should of fixed the problem), since it didn't yea that is the only thing left todo.
Sorry, I do not have a better answer for you.
but this is what its gonna take.
well then thank you
Good luck my friend.
