Transmission Questions
Hello,
I have a 2016 S550 4matic that I bought as a cpo. I’ve had it 3 years and driven 22k miles. Currently has 72k. Had extensive maintenance history performed at dealers only. Previously, I had a 2013 S550 which I loved - should’ve kept it but wanted to upgrade to the newer body style.
I’ve noticed harsh downshifts especially when the engine is cold (just started for a few miles) mainly downshifting from 4 to 3.
under cpo, during the last 3 years and 23k miles, I’ve had the following performed:
- shift adaptations performed and continued to have a minor “clunk” when the downshift occurs not under acceleration.
- CPO warranty covered replacing the trans and torque converter, this included new fluid, and I had the fluid changed as per maintenance schedule previously.
- I still noticed the clunk a few months ago and took it to the dealer during regular maintenance, they replaced the valve body, did a fluid change and adaptations.
- I'm still noticing the issue - is this common and should I just assume I won’t have issues down the road? I didn’t have any of these issues with my w221 (2013).
