I'm lost, i start my car and drive first gear is good and into second is good but from there to third it wants to jump in and out of gear and the RPMs go up and down, like it tacks like a lawnmower idling while in third gear.

Do you have any trouble codes? So, can you tell if this is a transmission problem or an engine problem? Please run the codes.
