#94 of 486 2001 Grand Prix GT won't shift into Park by bcarson1

I have a 2001 Grand Prix GT that has been giving me lots of problems lately. I think that they may be related. First was water getting into the blower motor, so I had to replace the blower and hopefully stopped the water leak with some caulking.
 
Then the power locks stopped working when you put the car in gear and when you shut the car off, they work OK if you push the lock or unlock your self.
 
I have been having problems getting the key out of the ignition sometimes too, this seems to come and go but I found a trick on the web to use a straw to unlock the key release.
 
Now the latest problem is that sometimes the car won't go into park. It will go through all of the gears but when you get to Reverse it won't go past that into Park.
 
Could the locks, key sticking and not going into Park all be caused by the same problem, and if so what could it be? I have a feeling that they are all related some how!

Hi, I tried to reverse my 99 Grand Prix GT out of the driveway this morning and the shifter seems to be stuck. When I apply my brake in order to engage the shifter from "park" to "reverse" the shifter seems to be stuck. I am parked on a slightly sloped driveway. The car starts fine however I can't seem to get it into any gear? Any suggestions would be greatly appreciated.

Sounds like you might be experiencing "torque lock". When parking on a slope, if the car rolls forward or backward in "park" after you take your foot off the brake, it applies tremendous pressure against the parking pawl--a pin that locks the transmission so it won't turn. Subsequently, when you attempt to take it out of "park", there is a great amount of side pressure against the pawl pin, thus making it hard to shift. Simple solution: Apply the emergency brake/parking brake BEFORE shifting into "Park".

A few things that come to mind 1. check the spark plugs. 2. check the air and or fuel filter. 3. Bad gas (dirty gas) try filling up with "premium gas" throw some gas line cleaner in with the fill up.
 
Try these things and let me know. Good Luck!!!

I was driving my Grandprix when it downshifted to passing gear I lost all gears but first. I got it back to my house then it set for a week. I had to move it when I got in it I had all gears back but reverse. When it gets warm I loose 2,3,and 4th again. what could cause this. I had no warning before I lost the gears

#101 of 486 Reverse to Drive Problem by grandprixman

Sep 13, 2007 (6:03 pm)

I have a 2004 Grand Prix GT2. It has about 68,000 miles on it. Sometimes when I go from reverse to drive, then step on the gas, it hesitates. It doesn't do it all the time. I don't notice any other issues. Do I have a possble problem? I have an extened warranty to 72,000 miles, so if there is a serious problem, I can get it repaired.
 
Thanks!!
