I am looking at 15/16 plated 350 diesel variants only (‘cos I like them!) not worrying about the HP - a remap to approx. 300 is a definite, these seem to be the bang in transition time...

Both were excellent auto boxes and I could not say there was a huge difference, my driving style I guess is more based on comfort with occasional spirited driving. The 9 speed is I guess slightly smoother and has seemingly a quicker reaction time. Robin

The only issue I had was it wouldn't always go to 9th as quick as I'd like it in auto, it would stay in 8th until I flicked the paddle. Only a small thing and it was down to how the box was programmed, I wanted more economy the box wanted to hold 8th. Much better box that the 7G with much better economy as a result.

A lot quicker changes than the 7 speed in my last (W212) car, and always seems to be in the correct gear. It still hesitates slightly on the paddles under harsh acceleration, but that could be my impatience. Also a lot better on fuel with the "glide mode" and high gearing. R

My alternator packed in on Thursday night and I managed to get home ,just, the last thing to shut down was the instrument cluster, phew, anyway ,I digress, my 30year roadside assistance has loaned me a c220estate with 9 gears, lovely transmission, around 70 came in at 1500 rpm, my 5 speed needs 2000 for the same speed, I don't suppose a swap is available?!!

It is, but you'll need to swop everything else over as well... You can transfer the boiled sweets tin though

I've had both ----the 7 in my SLK and the 9 in the SL - I find the shifting smoother and the change down (auto) in S and S+ really nice also the response to the paddles in the SL is a huge improvement over the 7g - much quicker - the 7g was really annoying it was so slow.

Previous one with 7g was a lazy diesel with a big engine which liked to use torque rather than revs. New on is totally opposite, petrol with the gearbox getting AMG tuning, I believe. The 9g changes are lightening fast compared to the “slush box” 7g. I find the initial changes 1-2-3 can be a bit rough but that may be down to me still getting used to a much more responsive throttle. Other than that, changes are smooth. The 9g is very willing to change down but I suppose the extra ratios are bound to lead to more changes. Haven’t got to S or S+ yet as still running it in! B

My SLK was a R172 - 3.5L petrol V6. That gearbox was the only thing I did not love about it.

As much as I like Mercedes and people might shoot me down, I’m with you on the ZF. BMW have done wonders with one in my lump. The shifts are stupid quick, paddles are almost instant and the box as a whole feels very solid.

Have to concur on this as it’s reflected in my 4 series, always tricky making direct comparisons but I’m super impressed with 8 spd ZF box in mine
