Not an intrigue, sorry. run over anything lately? A pinched cooler line could cause this. Or maybe just an old, gummy transmission.

97 grandprix code p0705 no check engine lamp on, but 1-2 gear shift is exteneded, then shifts also my scan tool shows 1-2 sel opn or shorted to ground..after driving for min but no code for sel yet


I just answered a P705 question that may be connected to this.
But I will add that usually transmission codes will not turn on a check engine light. The reason is the check engine light is to warn the driver that something has happened that could damage the cat converter or cause major problems with emissions.

06 pontiac grand prix shifting hard off a dead stop


If all gears are shifting hard, may have a code p1811 set-trans adapt long shift. When this code sets it commands full line pressure causing hard shifts. Usually the pressure control solenoid is at fault. You need to have it scanned for codes.

I have a 2001 grand prix gt 3.8 down to 15 mpg possible egr valve bad how do i check it has no power and barely climbs hills


Catalytic converter may be clogged. If engine light is on use the ODB-II code reader to find code. OR you could try disconnecting the cat from the Y pipe. Only do this if you can free up the bolts or have new bolts to replace broken ones. If you separate this part of the exhaust, fire up the engine take for a drive. If you have all power back then thats your problem. This experiment is loud though but worth it.

Hello, I have a 2000 grand prix gt shift into gear and drive fine


Sounds like the filter might be plugging up. I would have it serviced. Do you have a check engine light on? How long do you have to leave the engine off before it will start moving again?

Srs airbag light is on on my 99 pontiac grand prix


If the seat belt light comes on intermittently with the belt buckled, it may have a bad switch in the buckle or a loose connection @ the switch. This may also set a diagnostic trouble code in the srs control module & keep the srs airbag light on.

2000 Grand Prix does not shift into overdrive.


Could be a solenoid, there are solenoids accessible thru the bottom pan that control shifting functions. Do you have a check engine light on? If so An OBD2 scanner can tell you what code was set.
