7AT Problem?

Jordo! · 05-26-2012, 06:45 PM

Slightly clunky downshifting into lower gears on decel is normal... mine does that quite a bit, especially after manually operating the gears (the ECU learns your shift patterns, and "replays" them in regular auto mode.)

Unless you are hearing an audible "thump" or it's tooth rattlingly harsh, it's probably normal.

Still, if unsure, no harm in having the dealer check it out -- warranty!

I have the sport pkg but I have never manually shifted. Maybe manually shifting for a while will help the ecu? I don't really hear any noise just feel the car jerk forward as I brake down to about 20-15mph. But like I said only when braking hard...don't feel it while braking really slowly.
