I disagree with being manually shifted, thats work truck stuff, real supercars use paddle shifting, some are now using a clutchless manual transmission thats shifted with paddles. Others use a clutch and paddles.

And some just use a plain automatic without paddles that shift themselves you put it in drive and go, this proves the most consistent e.t.'s in straight line racing IMHO.

50 year old Powerglide automatics being widely used in all brands of cars in serious drag racing events drives the point home
