Question about 1999 Pontiac Grand Am GT
I have a 1999 Pontiac Grand Am SE which is making a humming noise. At first I thought it was the air compressor as that has been making a clanking noise and I do not plan to have it fixed until the Spring. But this new noise sounds like a humming or rubbing of band against something. I took it to the tire store as I thought it was a balance issue since the prior week with all of Michigan's snow, I had to get a car wash to get rid of the excess snow in the wheel wells. The car ran as usual but due to having to get unstuck at corners on the unplowed city streets, I had to rock the car, including putting it in the gear under drive. The last couple of days it has made this noise, runs great, but the noise it getting louder and I don't want to damage it, cause I like this car. I thought it was the muffler for a minute but it stops at stop lights or when you are warming it up, which a muffler I would not think would do. I had a relative drive it and he thought it might be the transmission as it did not seem to change gears with any noticeable movement, too smooth as far as he was concerned. His comment also reminded me that it has not shown any indication of shifting. I parked it we tried to find the transmission dipstick to no avail as from reading the manual and other internet info the transmission is sealed and the car should be taken to the dealer ASAP if problems are indicated. Unfortunately it's Friday night and most dealerships are closed on Saturday. Any suggestions??? Thanks in advance and sorry for the length but I wanted to be as detailed as possible.
I cannot say for sure but maybe a suggestion that it IS your transmission. The front wheel drive in these cars tend to cause problems for the transmission even at a young age. If you're driving around in the snow also you could be wearing out the gears prematurely. Sometimes a warning sign is the sound the gears make (humming and grinding) before one or more gears give out.
