I saw that TCM tuning is finally unlocked for the 8-Speed transmission for my 2015 Silverado 6.2l.
I've held off on tuning the truck for the last year because the transmission is so clunky and has been in a handful of times where they've "updated" the software for the transmission. Just curious if anyone has used one of the stock tunes and if it helped changed how the tranny felt at all.
Thanks.

Tons of people have done it, there are a few other threads here with people discussing the 8 speed tunes. No issues that I have seen.

Re: Silverado 6.2 TCM Tune
When I used this product I did not see any improvement with the transmission. I went to the dealership the other day and they just said to me that this is just a known issue with the 8 speed and that is just how they shift; especially when down shifting from 2nd.

Re: Silverado 6.2 TCM Tune
I tried the tcm tune as well and it shifted slower and softer than it did stock.. so I just tune the ecm and skip the tcm tune and use stock.
Re: Silverado 6.2 TCM Tune
Thanks for the replies, I was never notified that I had a response for some reason and had kind of given up on it. The dealership updated my tcm about a month ago and it seems to actually be shifting correctly finally. Now that GM has sorted out their issue I'll actually install the tune on the truck.
