Hello all, just posting for my buddy who owns a 09 challenger ss with an auto tranny. He says under aggressive driving the shift from first to second will drop him all the way down to 1k rpms, I'm aware of the skip shift in the manual trannies but in the automatics, any ideas what this problem could be? Computer or tranny? Thank you!

 

Never heard of a Challenger SS, but it sounds like a software issue if you haven't figured it out in the last 3 months.
