• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

    Where is the Transmission control module on an '08? Is this it?

    Ok, after opening up, then removing, the air intake box and tracing wire bundles all over the engine compartment looking for the TCM. I called Hwy 71 auto parts, where I had found pre-programmed TCM's for the car and asked them if they could help me figure out where this part was on my car. This...

    Where is the Transmission control module on an '08? Is this it?

    working on an '08 grand prix with the tranny stuck in park and it will not move. A friend told me that if I unplug the transmisssion control module and leave it off for a minute, then plug it back in it may reset it and fix the problem. If that doesn't work I'm going to at least get a new TCM...

    Not sure if this is the right forum, but where's the TCM located in an '08 Grand Prix?

    I've been trying to figure out a fix for my grandkids 2008 Grand Prix, and a friend told me that if I unplug and then reconnect the tcm it may fix it's non-shifting (stuck in either park or drive right now) and the reduced power showing on it's screen. Since it won't move, I can't verify that...

    New accelerator pedal reset procedure on '08. Need the procedure or steps.

    Forgot to answer before but, yes, one of the codes said something about voltage, but I can't remember if it said it was low voltage. I'm heading back over to the car (at the high school parking lot still) in a little while so I'll recheck that. I pulled the MAF housing off and attempted to spray...

    New accelerator pedal reset procedure on '08. Need the procedure or steps.

    Thanks, I'll check that. But it's not going to run right until I get it reset. The old one acts idles and acts fine when I give it some gas.

    New accelerator pedal reset procedure on '08. Need the procedure or steps.

    Thanks, tomsteve. I put the new pedal back in thinking that it must be the 'reduced power' problem hoping to reset it correctly and get rid of that code. I'm getting 3 or 4 codes on my scanner and they all point to the accelerator pedal. This really has me scratching my head. I've got to get...

    New accelerator pedal reset procedure on '08. Need the procedure or steps.

    Still working on my grandkids '08, which was showing reduced power screen. I put a new pedal in and it was idling badly afterwards, so I stuck the old one back in and the idle returned to normal. While I was looking up some info for other work on the car, I found a video on accelerator...

    2008 kicked into limp mode and doesn't want to shift out of Park. Help.

    I put a new shift interlock solenoid in yesterday. Then pulled it out to see if it was causing it but it didn't change. I got part of the dash off yesterday looking for a release of some sort, but came home to do some more research on what to do. I tried jiggling the stick, turning the wheel...

    2008 kicked into limp mode and doesn't want to shift out of Park. Help.

    Ok, today I went over and replaced a few parts, then when I was ready to leave, the damn key got stuck in the ignition! What the hell is going on with this car?

    Problem after installing new brake pedal position sensor. Help, please.

    Got the new accelerator pedal in today and no change. Also found that it won't roll backwards (slight downhill in the parking lot) so I could get AAA to tow it to my house so I can finish it there. I called my local towing guy and asked it they could get it out of gear or get the brake to...

    Problem after installing new brake pedal position sensor. Help, please.

    I will try that. And it may have happened because when I got to the car yesterday, the battery was dead at 2v. I ordered a scanner that will allow me to recalibrate the brake pedal sensor. Waiting on a brake pedal sensor I ordered from ebay. I don't know if it engaged or not. Usually when I...

    Problem after installing new brake pedal position sensor. Help, please.

    I'm working on my grandkids 2008 GP due to shifting problems and intermittent reduced power (limp mode). I've learned on forums and videos that sometimes the brake pedal position sensor can sometimes cause the shifting problem in conjunction with the gear shift solenoid, so I put in a new sensor...

    2008 kicked into limp mode and doesn't want to shift out of Park. Help.

    Thank you very much, Fordman. Even though she put a new accelerator pedal in less than a year ago, I've ordered another one and a shift interlock solenoid, to boot. I will definitely check all the grounds and wires. I saw a video yesterday where a guy changed out of few parts and then found he...

    2008 kicked into limp mode and doesn't want to shift out of Park. Help.

    My daughters '08 gp has developed two different problems. It's kicked into Reduced Power mode and I'm not sure where to start. I'm getting a few codes. P0446- Evaporator Emission system vent control circuit, P1125-Accelerator pedal position system, P2138 Throttle pedal position sensor/switch D/E...

    Question about iridium plugs - snapped off electrode

    I've been working on my daughter's 08 GP, and it's the first time I've had to use iridium spark plugs. I bought a set of AC Delco 41-100's, and didn't notice I'd gotten 100's instead of 101's, which is what it needs. Well, I always check the gap first, and the 100's are gapped at something like...
