Leaving work today I noticed that the shifts on my auto box is hard/harsh, like popping the clutch during a race. I didn't pay to much attention to it. halfway to home, suddenly it shifted back to third for no reason and the MIL comes on. I now have got third gear, i think, and reverse. Hooking 1st on the shifter does not help.
where can I start looking for the problem?
I bought a obd2 reader that plugs into my laptop and have various software to use and all of them indicate the same thing. no extra information.
