I had my car in to the dealer for an alignment yesterday after getting new tires on Friday night. When I made the appointment, they told me a transmission software update was available and would take an hour to install, so I had it done. It must have come out this week, since the car was at the dealer last weekend for the windshield trim/windshield replacement and there were no open campaigns at that time. The summary of the service visit shows it as the 37J1 update with Battery Load and Reflash Transmission Control Unit underneath it.

Has anyone else seen anything about this update? It seemed marginally smoother in terms of shifting on the way home, but nothing overly noticeable.

This was done to mine as well just last week. I know it helped solve some of the jerkiness in the lower gears, which I can definitely feel a difference in. Other than that not sure what else it updated.

Anyone have a TSB# for the update? Would love to get it when I take her in next. Thx

This TSB was issued back in Jan, 2013.
TSB-37-13-84
It's a software update that helps smooth out the 8 speed tiptronic 1st to 2nd gear jerkiness that some may experience. It is generally applied only when an owner complains of the issue. Presumably, models produced later already had the change programmed at the factory.

Apparently they're applying it now without people complaining first. Though the jerky 1st to 2nd shifts were sometimes annoying, I never mentioned anything to the dealer about it.

This one was TCM update 37J1 which became available early Dec. I believe they are doing this automatically now without bringing up the issue.

I brought up the issue a few months ago and they said everything was normal. I brought the car in for some minor warranty work last week and they applied the update without me complaining about the issue or bringing it up. Same thing happened to another A7 owner where they applied it automatically.

Thanks for the heads up. I have a 2015, and about the only issue I have with the car is that sometimes the shift from 1st to 2nd is not very smooth. One would think they'd have fixed it on the production line by now, but I'll be sure to ask about it when I have my 5K service.

Thanks for the info all - I've definitely noticed a bit of jerky-ness in the lower gears when both accelerating and decelerating (especially in Sport mode, but maybe it's just psychosomatic). Not a huge issue for me but it'd be great if it were a bit smoother.

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.
