1.) Replace the ignition switch module.

2.) Have your transmission flushed and refilled with a new tranny filter installed.

ok i did wat u told me still running sluggish and now i need help on that and can someone tell me why my brake lights and turn signals keep blowing fuses not the bulbs i change the fuses and they last for like 3 days then all of a sudden blow can someone tell me why

[ricksza]

The reason the fuse blows is because there is a short to ground in the wire that goes between to brake light bulbs and the turn signal switch or the trailer harness is shorted.

had the same problem, wasn't the ignition switch, it was the Shifting solenoid A, which is a thirty dollar part (AT THE DEALER). I got it installed and everything at the dealer, took them 10 minutes.

maybe it is the switch though, if the SES light did not go off, you need to hook up a diagnostics reader and clear the codes first. if the same code comes back up again, then I would take it to replace the A solenoid.

Sounds like you bent the float arm on the sending unit when you put it back in

i checked that out and everythings fine i got it checked out and they sed some kind of module do u know what that module would be

[Schrade]

Truck wont start and gas guage staying on full? Sounds like an electrical problem on re-install. Do you hear the pump prime when you turn the key on?

Hey diddy0071 - you said you changed Shift Solenoid A... You sure it was bad? I had the same DTC - P0753, but it wasn't broke...
