Yes , having the vehicle checked for DTC'S - diagnostic trouble code's should always be the first step in diagnostic process when any warning lamps are lit on the instrument cluster . Would be best to have someone with a professional type scanner , that can view engine sensor data . The engine coolant temp. sensor is a input to the PCM - engine computer . Can see what the actual temp. of the engine is . GM had bad stepper motors inside the instrument cluster's 2003 to 2006 , these stepper motors control the gauge needles . Testing what the real temp is an not going by temp gauge . harbor freight tools sells a tool under $30 bucks that can check engine temp . Infrared Laser Thermometer .. Point it at the thermostat housing . Can use it to tell what temp. the thermostat open . But , testing is the key ! Not guessing .

You should bring the vehicle into a repair shop that does tranny FLUSHES not fluid drop only. A complete flush will change the fluid in the pan, lines and the torque converter. SOunds like you have water in the transmission and the longer you drive it that way the worse it will become.

Not electrical. Your tranny does need professional help. I do not think that 2004 cars had electronic transmissions and solenoids for shifting.

gas caps are either vented, or non vented. it sounds like you needed one type but bought the other...... Just a possibility

What fluid were you told not to change? The automatic trans?

2004 Pontiac... | 55 views | 0 helpful votes

it could be a faulty brake switch, even the brake switch flicking would activate the abs/TC as computer would think its erratic driving.

Possible have a caliber not retracting all the way and the brake shoe is slightly scrubbing the rotor. Don't overlook the possibility of wheel bearings or CV joints.
