GTO Won't shift when floored

35

Asked by Jan 18, 2014 at 09:53 PM about the 2006 Pontiac GTO Coupe

Question type: Maintenance & Repair

I have a 2006 GTO 6.0L 4 speed automatic, I've had it for a week, and recently when
ever I floor the pedal down, it feels like a huge power lose, and it doesn't shift into the
next gear, and the check engine lights blinks for a few seconds then turns off, what
could it be? It has transmission fluid and everything. One other thing person before me
put MSD wires. But when I first bought the car and floored it, it worked find till recently
when I tried it again and it did this. Please help

Have it checked at advance or autozone. It should have stored a code in memory. They will check it for free. Post the codes on here and we will try and help you fix it.

No trouble or pending codes?

A bad gas pedal sensor will do this.

A flashing check engine light is warning you that the engine is misfiring and damaging the catalytic converter. Sounds like it's misfiring under load. Change those MSD wires and since you're right there a new set of iridium spark plugs wouldn't be a bad idea as well. I'd suggest using AC Delco plugs and wires. HTH. -Jim

msd wires are usually pretty good wires and if I'm looking at your reader correctly your just getting engine codes. your scanner must also be able to pick up transmission codes which I don't think it will. Most trans shops will check codes for free. A 2006 is all solenoid shift so either line press in low (worn clutches) or solenoid is bad. Either way they will tell you (if they want to charge you find another shop)
