I have a 2000 grand am. It acts like the transmission is slipping. The trac off and service engine soon light is on. When I first drive it it idles high then I have to pull over and put it in park then in drive 2-3 times them it'll kick in a change gears. How to I reset it to turn those lights off? I've unplugged my battery and checked fuses under the hood. Help I'm a single mom on a fixed income how do I reset those lights???? Thank you

So I actually really need some help with this, my car has all those lights on the dash and it runs really really bad and I plugged my obd scanner into it and it threw a code for the crankshaft position sensor circuit a so I replaced it and it still runs really bad and the lights are still on on the dash but it has not thrown the crankshaft position sensor code yet I really don't know what to do atp

You didn't specify the year, engine or trouble code (s). But inspect/check the wires between the crankshaft position sensor and the ignition module for damage. Trouble codes don't tell you what part has failed and the same code that you likely saw could be caused by a wiring issue.
