I recently installed a skip shift eliminator in my 2010 SRT8 Challenger as I despised that function. For me, it always seemed to cause a slight engine ping, not to mention the lugging of the engine. Besides, if I wanted something else to shift for me I'd have gotten an auto...

But anyway, the part number from BMC Performance is IZM993. Costs about $18. Easy installation. Even though the "Shift 1 > 4" still shows up on the instrument panel, I shift right into 2nd gear as God intended.

Highly recommended.
