Paul_’18 Silverado

I have a 2018 5.3 6 speed, all you guys find out what transfer cases you have, we’re going to do a little experiment, seems the clunk is an issues with the 10speed, 8speed and 6 speed...could it really be a shitty transmission!? if you have the same tcase as the next guy but he’s got a different engine and trans than you do, voila, Problem would not be the transmission and I’ll tell you why, my truck does not clunk in4x4!!!!!!!!! Wtf!!!! all you guys with the “clunk “ try it! Switch to 4x4 just before the clunk happens and see what you get!

So....is there a solution to this problem or more speculation?

I have a infrared thermometer, I did check the thermostat and where the needle was in the picture, my reading at highest was 96deg C. I agree that 120 is too hot, but why does it fluctuate that way and why just why, if the Obd temp is different than what I see, if I didn’t know any better, I’d be taking the truck in for a ghost problem thinning my pocket for non warranty covered diagnostics, I have never had this with any other truck I’ve owned. anyway, I’m at the point of doubt with this truck, between this and down shift clunk rough drive train, thin paint that chips easily, fuel saving gimmicks on a truck, cheap fisher price plastic dash and interior that creaks, rattles fastened by push clips...I don’t accept “within Spec” or “normal” according to gm anymore. Very disappointed with this $ 60000 truck, should’ve gotten that FORD I had my eye on. also the dealer we purchased from(not the dealer we use for service) had us sign a non resale clause or something to that effect, that would blacklist us with gm on future purchases should we sell our truck to the us market. At this point do I really care!? First and last gm I purchase . also, why does gm canada and gm us have different tsb bulletins for the same common issues on these trucks. Not bad grammar, it wasn’t a question...

Is it normal for the temp gauge to fluctuate? temp in picture is from idling and revving in park up to 3-4000 rpm with outside temp being 20deg C. It also climbs when accelerating up hill with no load at same outside temp of 20deg C...it does go back to a needle width below 100 right after called dealer, said it’s normal up to 120deg C. Anyone experience this? 2018 Silverado 5.3 with 27000km

So with all the threads I’ve read not one has a solution to the down shift clunk, I’m taking my truck in day after tomorrow for the issue. First stop was a tcm quick re learn, that did nothing, second stop was a tsb putting in insulators in the rear leafs, that did absolutely nothing, has anyone gotten this issue resolved or are we taking it up the ass by being told “this is normal” no, it doesn’t feel normal, It does feel like once off warranty they will fix it but at a high cost that wasn’t addressed while under warranty. My truck has 2700”km, been to dealer 2 times, had oil cooler lines replaced, trans clunk issues, Friday wil be again trans clunk, front suspension noises, rusty frame that looks 20 years old...$60000 2 year old truck and not happy at all! if anyone has a fix or knows what was done to fix the mentioned issues, it would be greatly appreciated.
