ok about 3 weeks ago i had my torque converter replaced and my solenoid pack in the tranny replace, my fluid is filled to specifications, what type of fluid does a contour use for tranmission fluid? could it be my TSS (Turbine Speed Sensor) its just weird , why would they have to reprogram my PCM in the same year it was made ? , but when i got it back from the trans shop it was low on fluid , so i added the right amount and evern since then it has that 1-2 bang shift after coming from the highway going 55-65 mph , but i shut my car off for like a min or so and it shifts fine , so any suggestions , i would apperciate it , oh and the trans shop is oderin me a TSS just to see if its that , cause i still have the sensor that has a metal bracket instead of a white bracket .......
