CL63 harsh downshifts
my 08 CL63 downshifts into 3rd gear noticeably harsh and rigid. it downshifts fine if i manually selected 3rd down from 4th. it is better in C mode but it is annoying in S mode.
is that normal?
thanks.

Try resetting the control module
A harmless kind of try - resetting the gearbox control module:
1. Get in to the car and close the door
2. Turn on the ignition (step2)
3. Press down the gas pedal / accelerator and hold it for 15 sec. (activate the kickdown contact)
4. Keep holding the accelerator while turning the ignition off
5. Remove the key and release the pedal
6. Wait for approx. 2 min. - U R done
Why? the software controlling the gearbox is adapting to your drivings style, and if you have been aggressive, the module adapts and expect you to continue beeing aggressive :-)
