Broken but but they were replaced started last week when i backed out of the driveway and possibly put the car in gear before it was at a complete stop replaced two mounts the dog bone and the trandsmission mount ( check engine light and trac off light came on ) . after repacing the mounts the check engine light went off . upon test driveing today the thump when transmission is going from 1st to 2nd is still there the check engine light went of but as the thump got wourse the light came back on it acts like one of the mounts are still broke they have been checked and they are not help any one
SOURCE: Coolant light keeps coming back on
more than likely these two are not related. You may have a bad thermostat or if applicable there's a sensor on the cylinder head that will regulate temperature that might need to be changed out (this is primarily located near the radiator fluid tube). As far as the thump thump thump noise i would need more detail to figure that out.

no you need to take it and have the codes pulled on it, the abs system will disable the traction control system.Without knowing what the codes are for the abs system it would not be possible to say what the problem is.
SOURCE: 2000 Cavalier catalytic converter was stolen/check engine light
The check engine light is probably indicating a catalytic converter malfunction the Oxygen sensor that is located after the cat tells the computer if the cat is functioning properly it is possible the wire has been broken or damaged. To see if the cat is there jack up the car and look under the passenger and driver area of the car follow the exhaust pipe from the front back the first thing the pipe comes to should be the cat it looks like a muffler with a wire going to a sensor after toward the back side of it, I doubt they never installed one but I guess it is possible.

Check engine light will not come on when a mount is broken. Likely the problem is inside the transmission.
