[OFFICIAL] Manual v. Automatic Thread

[ta-kid]

Are you saying that an AT without paddle shifters does not match engine and transmission speeds when downshifting? I don't believe that is true. All AT cars rev match or else they would just grind the transmission whenever they downshifted.

Yes that's what I am saying.My 2015 Toyota Matrix with a 4 speed auto does not rev match.All rev match on a auto is ,the ecu brings the rpm up before the clutches or bands (or however the particular tranny engages)engages the next gear down.On a normal auto the clutch or bands engage the lower gear with some inherent slippage and as they firmly lock together the RPM climbs to what ever speed you are doing,not before hand like a rev match.All my Trans Ams with Turbo 400,s never rev matched.As a matter of fact, I actually destroyed a case on a Turbo 400 tranny downshifting into second before I had slowed down enough years ago.Hence my forum name TA-Kid,mind u I am not a kid anymore or own any Trans Ams anymore either.
