SRM and DRM

It's called "Downshift Rev Matching" instead of SRM, but the effect is the same. All 7AT's have it, whereas only Sport 6MT's have SRM. |
The below is from another question on the forum and it says about the same as I did when I made the comment about how it feels about the same as other A/T's when downshifted.

In principle SRM and DRM from the auto trans work the same. The big difference is that it is much easier to do in an auto transmission because the computer is in control of the transmission, it knows what gear it is heading to and what the target RPM is. With a manual transmission it doesn't know what gear it is going to until you select it. The SRM system is a first, DRM on the other hand is pretty standard in modern transmissions.
