Very hard downshift when kickdown in low gears
First off all sorry my english..
i have a 05 w211 3.2 cdi. 5 gear auto
I have a problem with very hard downshift ehen i do a kickdown but only in the low gears 2 to 1 and sometimes from 3-1 or 2? .. if i press the pedal down to kickdown the shift i VERY hard and makes a "bang" in the gear ( i think) ?. in the high gears 3-4-5 there is NO problem when i do a kickdown .
any there maybe know a solution on this problem? or what it can be?
Thanks

What is your maintenance situation for your transmission? This is the 722.6 correct? Have you done fluid changes recently? Also, what about the transmission mount, has that been inspected and/or replaced? I would start with those two and then see if the problem remains. You can do the fluid change and replace the transmission mount very easily yourself.

Torque that reaches these parts is much higher at lower gears.

I would also check the pilot bushing/transmission connector, sometimes those get soaked in transmission fluid.

The solution is to replace the TCC solenoid and install a new torque converter damper kit like Sonnax 68942-23k. Since you'll be dropping the valve body this is also a good time to replace the conductor plate as preventative maintainance.

Further kickdown at higher gears isn't harsh and doesn't produce this weird sound so trans and TC should be ok in my opinion...

Not necessarily - afterwards you have a less stiff connection between engine and driveshaft, so the shifts will seem softer anyway, NO MATTER what the problem is.
