yea...when i read they wanted to charge you for eaach light i was like what (even the winsdshield fluid)..lol..but at least the car is running....u can try buying the scanner but the one that contains software about the crossfire is the ODB III and its about 4000 bucks on ebay and close to 7000 retail..thats why the dealer charges 80 to diagnose...but i dont think its a sensor because the car would either be running fine or not at all....if u shift hard,neutral revs, constant racing, burnouts through gears, all those things could affect the tranny because i've noticed the autostck on the n/a crossfire isnt made for performance..I think its small problem like circuit, or even tranny fluid ...do u drive it hard...how many miles does it have...tranny fluid need to be changed 60,000 miles...let us know what the dealership says when the car limps again...
