My pontiac engine get dead every time i release the gas pedal or slowing down even in neutral, i tried to look for idle adjustment but i dont know where it is located. also sometimes the gear is stock up...


Don't try to adjust the idle speed. Very very bad thing to do. Have your idle air control unit checked. Probably shot, or carbonrd up. Also have your throttle body cleaned.As far as the shifting goes, have the shifter interlock checked. These are both things that are better left to pros, as the diagnosis requires special equipment, and information.

Were do i add transmission fluid in my 2000 pontiac grand am gt


Automatics have a dipstick on the passenger side under the hood. Add ATF with a funnel, engine idling and transmission in park. Standard shift has an oil level plug on the side of the transmission.

Our 2005 Pontiac Grand Prix is hard shifting. The diag codes that came up are trans codes P1811c and P1819c. Does anyone know what these codes mean? I'm having an impossible time finding them. Thanks in...


The codes mean that the Electronic Pressure Control Solenoid is going bad. The computer detects that the shifts are taking longer than 0.65 seconds. Then the computer commands maximum line pressure to avoid burning out the clutches, hence the hard shifting. My 2002 Grand Prix had the same problem, and I had great luck just installing a shift kit to speed up the shifting and haven't had any further issues.

2001 GRAND am GT LOW ON POWER AND WON'T SHIFT UNTIL IT IS HIGH RPM THEN SHIFTS HARD AND DOES IT AGAIN TO NEXT GEAR. iF i LET OFF IT WILL SHIFT BUT VERY DOGGY. cHANGED PLUGS & FUEL FILTER BUT DIDN'T...


Check the transmission fluid the car needs to be running and in park to do so, if it is low that could be your problem if not look at the fluid it should be red, if it's brownish and it has a burnt smell to it you may need transmission work

My RPM is sometimes way too high on my 2000 Grand Am GT V6


There are a couple possibilities for this. One, the IAC (Idle Air Control) motor may be bad. But Ive also seen this happen when the TPS (Throttle Position Sensor) goes bad. However, when the TPS goes bad there is usually some changes in the way the car shifts (automatic tranny), delayed shifts, hard shifts, etc.

2000 VW Jetta squealing when shifting from 2-3rd and hard shift down when going up hill


hi if its just second to thrid then the clutch is slipping on thrid gear look at the boxes oil level is important but look at the colour is it red and tranperant as this is ok if its brown its a sign of the clutches slipping i would try a stall test on thrid gear first and if its ok second gear [manually] see is the engine stalls at the correct rpm if you thinkabout it imagine you are in thrid gear in a manuual box and suddenly drop into second it would be hard shifting it could also be a faulty thrid gear solenoid yates210456
