SOURCE: GrandAm Tranmission shifts hard
I had the same problem in my 2002 grand am GT. After taking it to a transmission shop and them telling me that I had all this stuff wrong with it that was going to cost me about 2700$ I looked elsewhere. I had an Intake Temperature Sensor that had went bad. It was registering on the check engine light after the fact. I changed it and then found out there was a loose wire in the connector. I fixed that and havent had a problem with it since

BANK 1 SENSOR 1 IS THE ONE IN THE EXHAUST MANIFOLD. BANK 2 SENSOR 2 IS BELOW THE CATALYTIC CONVERTER.
P0171 SHOULD GO AWAY WITH A GOOD O2 SENSOR BUT DO CHECK FOR VACUUM LEAKS TO BE SURE. 3.1/3.4L ENGINES HAVE A BAD DESIGN INTAKE MANIFOLD GASKET, THE LEAK OIL, COOLANT, AND AIR.
