Pontiak said speed sensor bad. did not change. stopped at stop sign and car wont move. diagnostic machine code said torque convertor locked.. could this just be the speed sensor. never had any transmission slipping or anything
SOURCE: transmission wont go into any gear except reverse
NO I think your forward band broke can you manually shift it to low & car moves If so you need trans overhaul. Don't have that mechanic fix your car he is full of it if converter failed or (SENSOR!!) you would also have no reverse

i wouldn't be looking at the o2 sensors! look at the coolant temp sensor! when the car is cold it doesn't correct fuel & air ratio until it is warm so it is not looking at the o2's till then! if the sensor is bad and telling the computer it is warm when it is cold them it would be leaned out and run like that then when the car gets warm it's fine because the sensor is still saying it's warm! would be the opisite if it went bad and was telling the computer it was cold! that is a sure sign of the temp sensor being bad! good luck
Testimonial: "Thanks. I'll look into that. Coolant sensors are a lot cheaper than O2 sensors too. :-)"

The forward clutches are going bad is the most likely problem. To repair the trans should be rebuilt.
Testimonial: "That's what I was afraid of, a total rebuild. "
SOURCE: CAR WONT START,OBD SHOWED EGR AND MAF SENSOR
well the egr could be stuck open acting like a vacum leak,,,and causing the car to stall,,,you need a new egr,,,,check the wires and if any vacum hoses that go to it,to make sure they are good and connected first,if so replace the egr,,,,it could be false dtc for MAF sensor,,,
SOURCE: gear type noise when driving.noise changes with
Hi, if this noise changes when turning left or right, (gets louder or quieter), there is a good chance a front hub is bad. For instance, if you turn right, and the noise gets louder,the left hub is bad, and vice versa for the other side. You can normally jack it up, spin the wheel and hear the noise, or wiggle the wheel, and see if it has play. Good luck...
