The thing is I can't remember noticing this any other winter... I do tend to notice things like battery charge/engine temp etc. Thanks!

Hi guys, I've got a 2016 GMC Sierra 1500 5.3 and recently this winter I have noticed that when it gets "cold" i.e. anything roughly 45 degrees or below the temp gauge doesn't quite get to center. It stays roughly 1 dash below center even after allowing the truck to fully warm up. During my commute which is on city streets it doesn't warm up all of the way. I have included a picture to demonstrate what I am seeing. I cannot remember this ever happening before although I am reluctant to take it in if there is anything I can do on my end to fix it. Does anyone know of any TSB's out there that might address this issue? I have done some searching on the forum but nothing seems to quite replicate this. Most of the TSB's seem to involve radiator issues if i'm not mistaken? Also this picture is taken when it is 10 degrees outside. Anyway, thanks for all of your help! Keep Trucking!

good luck! i did the fluid flush and it helped but still acts like a drunk sometimes...

anybody know how much a cleaning would cost?

Hey Guys, Has anyone had to clean their intake runners yet? I know that with the DI injectors there can be an issue with carbon fouling as the miles rack up. Has anyone had a problem with this and had to have it cleaned yet? Ive got about 35K on my truck right now. Thanks!

when is blackbear in town to do a tune? any other companies that tune the 8-speeds?

what type of fluid? exact model number?

what type of fluid should we use then? specific weight and type

mook its honestly 95% better so I never took it to the other dealer. i dont have that much time in my day. Im taking off for a whole week in mid april over good friday so i might meander my way into the other dealer then to take a look at it. as far as the bilsteins they are firmer but also not firmer. its tough to explain. hitting speed bumps the truck doesn't bottom out like it used to which would make it seem like it is softer however you feel more minor road imperfections which would make you think that they are firmer, its not harsh at all. very little body roll compared to the stock ranchos and almost zero squat or dive. honestly it drives like a 50K truck should have from the factory. money well spent in my opinion.

after my most recent software update it is def better but i still think im feeling the TC issue. I'm just sick and tired of dinking around with this... on a seperate and totally unrelated note i installed bilsteins 5100's on all 4 corners and it handles like a dream now!

imagine a rough road/ rumble strip/ surging/ misfiring feeling that goes away when you back off of the gas. thats my impression anyway

update: seems to drive ok but i swear i still feel like its slipping a little bit at steady state throttle and i feel that the only people who know what I'm talking about are those who have experienced it. Ill give it a few days and report back. the downshifting coming to a stop is way better but I'm not sure if thats because the truck is back in its learn mode... any help here guys?

hopefully the 3rd software update is the charm! But I'm not holding my breath...

just got a call from the SA. said they did some sort of adaptive relearn for the tranny and that there was some incorrect software loaded into the transfer case. correct me if im wrong but the transfer case is only utilized to engage 4 wheel drive... we shall see if this works and if it doesnt ive already spoken with another dealership who is very familiar with the issues surrounding the torque converter. i will keep everybody updated.

If they replace the TC do they also replace this Stator Shaft that others have talked about? Seems like that is also a problem?
