Pontiac - Grandam :: 2002 GT 4T45E Transmission Shift Flutter Between Third And Fourth
Apr 17, 2014
My sister's Grand Am has been having a shift flutter issue (between third and fourth, around 40 mph it would shift rapidly back and forth until you either forced a downshift or reached 50-55 mph) for a while now. I read a lot about it online, and all signs and the experiences of others pointed to a bad shift solenoid or pressure control solenoid. I wanted to correct the issue before it caused any damage to the transmission. I removed the transmission from the car and replaced both shift solenoids, the torque converter clutch solenoid, the pressure control solenoid, and the manifold pressure switch with new ACDelco parts. I figured I may as well replace them all while the trans was apart. I also replaced the filter and fluid, of course. I got everything back together, and now the transmission slips in reverse and overdrive no longer works. Fluid level is full according to the method of pulling the level check fill plug while hot, idling in park. I used Valvoline Maxlife fluid, which meets Dexron VI specs according to the product label. I have double and triple checked everything and can't even fathom what I could have done to cause these new symptoms to crop up.

I have a 2002 Pontiac Grand AM for about 4 days now the car has been running hot. When it gets too hot the car dies and I have to jump the battery. Could this be more then a simple thermostat problem?

I have a 2001 pontiac grand am se 4cyl with an automatic transmission and I've been having issues with my transmission, about a month ago the transmission started shifting hard then just went out so i took it to a transmission repair shop and the tech said that it was the pulling clutches and i told him to completely rebuilt the transmission including new electronics and torque converter and he did i got it back and it drove fine for that day then stared doing the same thing my transmission slams into gears and I don't know what the problem is sometimes ill be going down the road and the transmission slams and then the trac light comes on for a little bit then goes back out??? also some days i can drive it a mile or 2 before it starts slamming into gear.. what this could be causing it to slam i would think it couldn't poss be the transmission as everything has been replaced? could something else be causing it to slam into gear..

The turn signal noise in the hazard light terminal will not shut off. Should the terminal be replaced or is it some other electrical issue? 2002 Grand Am

I have a 2002 Pontiac Grand AM GT with 151,000 miles (I have had the car for 6,000). I recently just changed the oil with 5w-30 which is the 3rd oil change I have done and have used the same brand and viscosity. It seems the oil is a little overfilled this time (maybe 1/4-1/3 of an extra quart). I noticed a knocking coming from the engine (closer to bottom of engine than top) on a cold start. It sounds like a rock being knocked against a hard surface. I can only hear the knocking if I am outside of the car, if I am in the car I can't hear it at all. The knocking lasts for maybe 20-30 seconds. If I press the accelerator (when in park) the knocking goes away, and if I let off the accelerator then it comes back. I can't really test to see if the knocking persists while driving since I can't hear it from the cab.
I know I should do all the routine maintenance when getting a used car (spark plugs, etc), but I bought from a friend who put spark plugs on maybe 25,000 miles ago.
I read that maybe I should be using different viscosity of oil in the summer (even though the manual says 5w-30 all year, I live in North Central Nebraska)? Is the knocking maybe due to the slightly overfilled oil? Should I try to drain that excess out? Should I just go ahead and replace the spark plugs and wires as well?
I drive ~750 highway miles a month and hope I can get this car to last a few years. So far it seems pretty good, have only had to change the ECT sensor and thermostat on it, suspension bushings still look good. I just never heard this noise before and it kind of freaked me out. I probably would have never heard it but I just happen to start the car and needed to grab something from the garage.

Fuel pump went out, took it to garage to have it fixed. Got it back...now I have no headlights, taillights, or dash lights. I have turn signals, break lights, and brights. I've checked fuses under the hood, and on both sides. Replaced them all twice just to be sure. I've changed the ignition switch and the multi-function switch. I'm at a loss!

At work we bought a 2003 F-250 at an online auction. I was driving it home, and when it shifts into fourth gear, (overdrive) a vibration develops. When I pushed the overdrive lockout on the gear selector and it downshifts to 3rd the vibration pretty much goes away. Turn OD back on and it upshifts and the vibration is back. The transmission seems to shift through all the gears really good / smoothly and is glass smooth when you go from Reverse to Drive. What could this be; fourth gear going out, sticking valve in the tranny, drive shaft off balance? Just not sure where to start on this one.

Last night when I was driving home, I noticed that all of my "night lights" were off. The lights on the speedometer, gas gauge, gear shift, etc. did not seem to be working, but all of my system warning lights (Traction, Brake, etc) seemed to be fine. I tried to turn the car on and off a few times and also tried fiddling with the lights manually. Nothing seemed to be working.

I have a 2000 grand am Gt with 3400 motor it started up just fine went to turn around in the drive way the dash lights came on where the ABS sensor is bad, but if u shut it off and started it back up they would go out so i shut it down and went to start it back up and all it does is click, so i thought it was the starter and replaced it, still only clicks. I called GM dealership they said more then likely it is the plastic piece the ignition switch goes in to so i just replaced it and does the same thing.

This is on a 2004 Pontiac Grand AM.
The old GM ABS light problem. The lights were on a month ago and the left front hub was replaced, the light went out. They just came back on all of a sudden (coincided with the temperature dropping to 15F). The next day they were out. Then the next day they came back on. I couldn't get a code read with the basic scan tool.
Where should I start? I'm thinking of cleaning the speed sensor connectors and reseating with dialectic grease. Maybe they're dirty or a bit brittle due to age and the cold?

I have a 2004 Pontiac Grand Am with about 130k miles on it. For some reason my car has been dying lately. It did this a few times so the obvious thing was to buy a new battery- oct 2011. Everything was good for a couple months but I recently went on a trip for the weekend and when I came home the car was dead. I jumped it and everything was good until this week. I had a work conference and left wednesday at 8am. When I got home Friday at 5pm the car was dead again. I had an alternator test done before but could it be the alternator? I love my little car and would like to get a couple more years out of her!!!

Have a 2004 Grand am that was having some problems starting:
1) The last 10 times it would start cold, but it would take about 5-10 seconds of turnover before actually starting.
2) After it started, it would start fine the rest of the day.
Now it will not start at all. Today is the coldest day of the year so far... 43 degrees. It tries to turn over. The security light came on once, but did not come on again (i know that's a common problem). (note: I have not seen it in person, but will later today). Either fuel or spark.
My thought: either fuel pump, fuel pump relay, sensor, wires/plugs, etc.

I have a 2004 Pontiac Grand Am with a 3.4L engine. When I start my car after it has been sitting for a while, especially in the morning, the engine shutters making the car shake when it is put into Reverse and Drive. Plus a horrible gas smell come from the hood and into the heating vents. So to alleviate the shaking I let the car run for several minutes which in turn makes the gas smell worse. The smell continues to get worse when the car is stopped at a alight or stop sign. to eventually go away as the car heats up. The check engine light blinks with the shaking then disappears but eventually stayed on with a cylinder misfire code. I took it to a shop who told me that was the head gaskets.

I just got a 96 Grand Am for second vehicle, but it won't blow any air (hot or cold), I checked fuses they all look good. I'm thinking possibly blower motor, but wanted to get some feedback before I start plugging away.

So, a couple weeks ago, while driving down the highway, my '99 Grand Am had the oil lamp come on, and the engine was running rough. I pulled over and stopped the car, and then went to try to start it, to no avail. The engine wouldn't crank. After getting it home via tow truck, I charged the battery as first aid.Now, with the charged battery, the engine will start, and run very roughly, as in shaking the entire engine bay. Further, the oil lamp is on now. After a minute of running like this, the engine dies off. Stepping on the gas expedites the stalling out. I've checked and filled the oil, and the coolant (which was low). My next guesses are fuel filter and timing belt.

2001 Grand Am, 120,000 miles. Struggles to starts, when it does turn over it is only for 1-2 seconds and then cuts out. Even if I get it plenty of gas it still cuts out only it revs and then cuts out. It worked fine on Thursday and sat on the drive until this morning. If it makes a difference, we've had lots of rain recently and the remote keyless entry stopped working too.

I have a 1999 Pontiac Grand Am coupe. Over 195,000 miles. Not worried about someone stealing it This past month we have the SECURITY light come on and blink.It's do that 3 times. Two times I remained in the car, with the windows down, while my wife was in a store, with her keys. I have my own, but just sat there reading, no A/C or radio on, According to the manual, it is an anti-theft "feature". When it does the computer shuts off the fuel and the car won't start. It turns over. We have to wait until the light goes off, then it starts. Dealership says they can't disable this "feature". They said it could be ignition switch or computer $$$. What can I do?

When mother purchased car she wasn't given an alarm fob. She just locks the doors. One day the "Security" light comes on and the car acts like there is a kill switch on it. Can't seem to locate the problem. She purchased it used in another state.
