I had the famous warning light trifecta... Forums i had searched said it could most likely be one of two things: abs module or wheel speed sensor. since i lost my temp guage as well as rpm, i ruled out the wheel speed sensor. I had took out my abs module, very simple, and shipped it to cheap-abs, one of the abs places that came up on google, and for about $120 it cleared the codes and it has been driving/shifting like perfect. Hope this helps!
