Transmission control unit software update

I just got back from the dealership. I was told that this is a new "recall" initiated in December 2014. Other than that, there is also new steering software update. These 2 recalls are mandatory. I refused the steering software update but was told I dont have a choice. I should have more detail when they are done later today.

Brought my A7 to the dealer a couple weeks ago to get some work done, and they also did the 37J1 campaign (invoice says "37J1" and "UPDATE TCM SOFTWARE"), which apparently fixes some of the transmission control module settings/mappings.
My impression is that my S-mode is now more like I would expect it (I previously was feeling like S-mode would get lazy like D-mode at times), noticeably becoming more sporty when I change from D, even if I'm just cruising along not too aggressively. Now it almost always downshifts one gear when I go from D to S, and maintains the revs a bit higher. Looks like Audi got it right with this update!

I concur with this.

My 2013 D to S behavior always downshifted by a single gear "out of the box" at delivery. The transmission software updated in my car in July 2013 changed the behavior by almost always forcing a more satisfying two gear downshift resulting in a more noticeable, "sportier" performance. Not sure what this new update adds or changes.
I'll have to double check for new updates when i take it in.

Just had my 2012 in for another issue. Did the update. FWIW, the service writer said that he thought that this update had something to do with emission control issues rather than shifting behavior. I didn't notice any difference afterwards...but it was shifting smoothly before.

As for the transmission update, it is definitely a newer update than the one released some time ago to fix the 1-2 2-1 jerkiness. Not sure if it is placebo effect but shifting seems smoother and crispier.

I specifically asked my SA for the TSB, and he said "there's no TSB, it's a campaign". Here's what's on my invoice:
I used to only notice the jerkiness 1-2 when first pulling out of my garage in the morning. This TCM update seems to have softened that out.
