Can I drive with a transmission problem?

If your Pontiac Grand Am can still make it up and down the road, you might say “It’s fine, I’ll just drive it until I can get it fixed”. But that is not always a good idea, depending on the symptoms. You see, there are a lot of (very expensive) moving parts inside of a transmission, and if something isn’t right, continuing to drive with a transmission problem could damage something else.

How often does a Pontiac Grand Am transmission need to be replaced?

The overall lifespan of a Pontiac Grand Am transmission largely depends on how well it was maintained. Factory design flaws also factor into this equation, along with how/how hard you drive. But on average, we’ve seen the Pontiac Grand Am transmission last for between 130,000-180,000 miles. A high quality replacement transmission however, can last considerably longer if all of the factory design flaws have been addressed and the vehicle has been maintained.

How are Pontiac Grand Am transmission issues diagnosed?

It is fairly easy to guesstimate what the root cause of your Pontiac Grand Am transmission problems might be, but you won’t truly know unless you have the right tools and experience. A good mechanic or transmission repair center will be able to connect your truck to a computer and find out which diagnostic trouble codes (DTC’s) have been stored. Once they know what to look for, they can perform a visual inspection to verify the problem.

How is a Pontiac Grand Am transmission replaced?

In order to replace your Pontiac Grand Am transmission, the truck has to be lifted from the ground in order to gain access to all of the parts that will need to be unbolted. Then the transmission can be lowered to the ground (typically with a transmission jack), so the new transmission can be installed. Once it is in place, for the 6L80, the vehicle PCM will have to be reprogrammed / reflashed to accept the new transmission using the latest GM subscription.

How to Solve Pontiac Grand Am Transmission Problems

Solution A: Buy a Used Pontiac Grand Am Transmission

The quickest way to fix your transmission problems is to simply buy a used transmission or used transmission. These can be found at most junk yards, and they often come with a 30-90 day warranty. However, there’s no way to determine the actual condition of the internal components, so you could be spending a bunch of money to have the exact same problems. Plus, that warranty only covers the transmission if it’s defective, not the labor costs that you’ll have to pay.

Solution B: Buy a Rebuilt Pontiac Grand Am Transmission

Another option would be a rebuilt transmission or rebuilt transmission. A local repair shop will remove your transmission, then install a bunch of new parts during the rebuild. The problem here is, the skills and experience of each transmission rebuilder will vary widely from shop to shop, so you could have problems from something that wasn’t adjusted properly. And the 1-2 year warranty might only cover you at certain transmission repair shops, in a specific geographical area.

Solution C: Buy a Remanufactured Pontiac Grand Am Transmission

Many owners depend on their vehicle to commute and get things done. Their gasoline engines are designed to go 100’s of thousands of miles, so it makes sense to invest in a remanufactured transmission.

Bangs when put in drive

I have a 2004 Grand Am GT1 with 198k miles. As far as I’m concerned it’s the original trans. Considered a replacement. My issue is it will drive fine if I have it in selection 3 but if I put it in drive the trans will receive up to 4000+ rpm before even trying to shift. It only does it in 3-4 and does this randomly going down the road. I had the trans service with new filter and topped off fluid at 182k. My thought is that a solenoid has gone out or a control mechanism is having issues. I have no trouble codes at all so this is why I have given all these details

I have a 2004 Pontiac Grand Am 3.4L V6 with 306,000 miles. I’ve kept up on maintenance but the car is shifting into drive very hard, and will not shift into 3rd or 4th gear when cold. Also I’ve noticed it’s leaking underneath in a few different spots. Going up hills, it has no power and when downshifting to go up a hill it will downshift and then quickly shift again. I’m completely lost….

I have an 03 grand am gt with the 3.4l recently it has been hesitating past 80 kms it shifts fine sometimes but other times really hard I changed the fluid and filter hoping it would work itself out but still nothing changed. I bought this car at 136000 kms softly after I could hear like a grinding kind of him from the front end. Where the drive axles hook in. It not has 230000 kms on it the last 20000 kms I put on it there is a clicky kind of hum noise where the torque converter is i guess my question is if my torque converter is going would my transmission be ok yet ? When I changed the fluid it was pretty good yet and wasn’t a whole lot of metal shavings in the pan or the magnet. I’m not getting any codes at all ether. If I were to change the torque converter would that mabie solve the slipping issues.

Transmission shudders or shakes only when taking off. Recent forgot to hook the upper trans cooler line up and car ran for about 20-30 seconds, filled it back up and started doing this

I have a 2002 Pontiac grand am GT with a 3.4 and 139,879 miles on it. Recently if I just take of nice and really slow it will shift fine, but if I have to give it gas it falls on its nose and I have to give it more gas, then it raps out and does not shift properly unless I let off the gas then starts to slip unless I assist with the gas peddle. Any suggestions?

I have an 04 grand am gt. The transmission will only shift from first to second gear then you can run all the way to red line at 80 miles an hour and let off but no shift it has 183000 miles on it fluid full. There are no trouble codes stored in computer system and no mil illuminated

My 99 grand am gt has just over 200k miles. It just started slipping in first gear, the motor revs up but no go. I put some lucas trans. additive and a qt.of fluid just hoping it was just low. Either it’s still low or it’s something worse. I don’t have it close to where I can get it off the ground to check level. Any suggestions

2002 Pontiac transmission doesn’t want to go in drive or reverse when it gets warm. I was told there are 2 lines in the transmission that need to be re soldered or brazed is this true
