Dec 06 2005

I also have a 2000 Grandprix. Right now I have about 115000 miles on it and I had to replace the Transmission once already and without an extended warranty. So I had to pay out of pocket (OUCH). That was a couple of year ago and now the Transmission is starting to shift slow or late and hard. Does anyone know what's causing this? Thanks.

In response to the July 18 comment, I had the same problem with my 1992 Olds, a stuttering at 45mph or so. From watching the tach, I found this was always because the car shifted into 5th at about 45, then didn't seem to have the power to move up moderate hills in that gear. Yes, I know, it's supposed to be a 4-speed transmission with overdrive, but that's not like a Toyota overdrive, which merely changes shift points. In GM cars, it's a fifth gear. If anybody wants to argue that it's not a "real" gear, then none of the others are either. Just like reverse adds a cog to first to make another gear, 5th, or "overdrive," adds two cogs or so to 4th. Anyway, about the stuttering, it was only fixed in my car because the engine blew, so any worn-out parts connected to it got replaced. Turned out it was something called the "kick-down" cable. Since that was replaced, I haven't had that stuttering at all. It used to feel like it was going to stall if I tried to accelerate at the wrong time. I had to run it in regular "D", effectively making my car just a 4-speed, as opposed to that little D with the circle around it, for "overdrive." Hope that helps somebody.

I also have a 2000 Grand Prix SE that has hard shifting problems. It's been like that for the past 53,000 miles. It has recently gotten worse, stutters and bucks at 45 mph, especially when going uphill. At highway speeds and on flat driving, it seems better. Codes are coming back with a long shift issue (I have no idea what that really means).

At 103,000, I really should spend the $2000 to have a new tranny put in, but don't have the money. I just go with it and keep my fingers crossed everyday. This is my first Pontiac, and undoubtedly will be my last.

I also have a 2000 Pontiac Grand Prix GT. The car seemed to shift slowly after running for about a half hour (mostly at stop lights and in slow moving conditions). Then it started to make a high pitched noise every time I accelerated. One morning the Check Engine Light came on and I drove about 10 miles, stopped at a stop light and the car wouldn't go any further. I was stuck at a major intersection. I have had quotes on fixing the car between $1700 and $2100. I love the looks of the Grand Prix and the ride, but I will never get another because I hear way too many bad stories about this problem.

I bought new a 2000 Grand Prix SE, absolutely love the car, but have had transmission issues since the first cold day here in Tennessee. I have done some research and found that the transmissions on this year model car has some problems. I have been told it is everything from how I drive to spark plugs. My problems are only during cold weather, which leads me to believe that it is one of two temperature sensors contained within or around the transmission. I have taken it to the local dealer, and the can't get it to "recreate" the same surging that I deal with every cold morning. I haven't bit the bullet and taken it to a transmission specialist, but am going to have to if I want to keep the car. Car now has 105,000 miles on it, and really no other issues to speak of.

Just add my name to the list of individuals with a 2000 Grand Prix GT sitting in my yard with a bad transmission. My Pontiac died at 104,255 miles. The month before the transmission went I took it in to a dealer who throughly checked out the vehicle, and it came back with a clean bill of health. It started by slow shifting and then I started smelling a different smell. I took it back to the dealer to find out that I needed a new transmission (1 month later). And the funniest thing is that I made the last payment on the car 2 months before the transmission went out, so now I own free and clear; a beautiful red lawn ornament.

I was offered a 2000 Grand Prix GTP, for $2000. I was told it has transmission problems when going around 45 mph. I am thinking about buying the car and just driving through residential streets so I won't be going that fast. Does anyone know if this will cause more issues? I was planning on saving $800 for a transmission from the Junkyard and try and put it on with a couple of friends, does anyone know how hard it is to do this? Also, when purchasing the transmission, should I ask for one for a 2001 so I don't get the same problems, will it work?

I have a 2000 GTP I just purchased and I had problems with the car jerking. I took it to a tranny shop and they said my tranny was shot. They wanted $1500.00 for a rebuild, I didn't have that much money, so I went to Nordstom's and purchased a used one for $800.00 that only had a couple of miles on it. I then went to put it in. I work with a guy that's a pretty good mechanic, so he and I put it in. Took about eight hours to do and wasn't very easy. When we were finished it still ran kind of rough. A couple of nights of driving the car did the same thing. I then took it to a local mechanic shop and had it hooked up to a computer. It was reading a mis-fire. I had already changed my spark plugs, so I changed the wires. When I went to change the wires, the cables were ruined and the distributor ends were badly corroded. I cleaned them off and put the new cables on. The car runs great now. My advice to you guys, is always look into your problem further before doing something drastic like I ended up doing. Oh, by the way, my car has 80,000 miles on it, with a new tranny...ha-ha.

I have a 2000 Grand Prix GT. Currently has 150,000 kms on it. I changed the tranny fluid at 118,000km and recently spent $1600 on brakes, plugs, accessory belt, battery, fuel filter, rad flush/fill, etc... just to be a good car owner and keep up on regular maintenance. Over the last 10,000km the tranny shifts hard through all gears. It is not consistent though as it could be there on one trip and not on the next. It is happening more frequently though. Now the question is... do I cut my losses and trade it in for one of those fancy new '06 Honda Civic's or spend another possible $2,000 on a transmission? Sounds like the hard shifting is a common transmission failure occurrence in these cars. Yikes!
