2002 Pontiac Grand Am not shifting properly

We have a Pontiac Grand Am 2002 with a 2.2 Ecco-tech engine. A few months ago it started having issues. The Speedometer started bouncing, car wouldn't shift out of 1st, and then the check engine light came on, and the trac off light. Then speedometer didn't work at all, the car didn't jerk anymore, but it did take a few blocks to shift. One night it went 30 miles before shifting. In the middle of all this, our mechanic replaced lower speed sensor, but the whole thing started over again. He replaced the sensor again and recommended if the lights come on again, to do a trans fluid flush, replace fluid and filter. Well after this it started again so he said to save some money to replace the two wires to the sensor. We don't have the money to keep playing guessing games. Could the plug be bad that goes to the sensor? Any ideas?

Guessing is a mugs game especially when there is a an ECM program that stores and reports all faults
all the mechanic should be doing is reading the fault codes and fixing what is found
you can go to places like auto spares shops and have the codes read free so that you know what needs fixing

If wiggling the wires cured the code, then one of the wires is broken inside the insulation. Pull on each wire one at a time. look for the colored insulation to stretch, this will be the broken wire. For the other car that wont rev up, this is a common when the catalytic concverter is plugged up. This will also cause MAF codes, and in turn, TRAC OFF light.

SOURCE: trac off light

I fixed my car. It cost me though. The problem was the coli pack. My car was misfiring, my mechanic checked the injectors and the cylinders, thankfully neither of those were the problem. It was the coil pack that went bad and caused it to misfire

i agree with what white is saying also if you are still having a problem with it you can take it to mike's transmission service on rt 57 in ny. up the street from longly brothers. also i was wondering if you put enough fluid for the torque converter to have to check this while it is running.

My 2003 Pontiac Grand Am whistles when I accelerate quickly and always when I am going 40 mph or more. It also recently started to shift differently, it feels like it is taking longer to shift.

The first thing is to make sure you are not low on transmission fluid. I would expect more a whining noise than a whistling. But the slower shifts may definitely indicate a low fluid level and/or fluid that is long overdue for a drain and refill.

Pontiac grand am stalling

A lot of possible causes - have you checked for trouble codes (DTCs)? If no codes, given the age it could be in the fuel delivery system (for example, fuel pump stopping either due to an intermittent electrical problem at the ignition switch or in the wiring such as corroded connectors).

If tranny fluid is clear and at normal level, then the issue is with the transmission - it is getting ready to go sayonara.

Better get that fix before you get stranded.

I bought a 2002 grand am about a month ago and i am having problems. when my car has to shift gears it takes a long time to shift. i will be going down the highway and i am stuck on 50 and it won't shift....

Check the transmission fluid level, per your owners manual. (Some transmission fluid levels need to be checked cold, some hot with the engine running and some hot with the engine off) Most hot with engine running.
If your level is good, and the fluid looks reddish or maroon, bring it to a trusted local mechanic. He/she will be able to determine if you have a blown transmission or if bad solenoid(s) are to blame for your poor shifting. Transmission solenoids cannot be checked by the average person in their driveway.
Dark brown or black transmission fluid means the transmission was not serviced properly and the fluid "cooked" and a fatal internal failure has occured, or vice versa.

1993 Pontiac Grand AM rear Brake problem. Seems to happen only after the car has sat overnight or in the rain. Mechanic sees no physical problems. Has cleaned, bleed, etc. The ABS light did come on a few...

You don't say what the rear brake problem is. Do they screech? Could be rust. Did the tech put the rubber plugs back in the backing plates? They keep out water and condensation. Look underneath the car at the backing plates; there should be elongated holes there. Some techs neglect to lube all the components when they do a brake job. Hmmm, some of those Grand Am's have disc brakes in the rear instead of drums. They stop better but they're more trouble.Might try a different tech. (One with GM experience), Good Luck.
