NotoriousGT350

Had dirt everywhere inside and out. Spent Friday and Saturday cleaning her up. Here's a cold start below. Stock, nothing done to it. It was 33 degrees when filmed yesterday.

Like one day go back to Ennis. Been 20 years since I went when they had the Fun Ford Weekend over there.

I’m really considering not buying another GM truck. Parents Acadia engine went out, wife’s Yukon transmission went coming back from cali last August in Az costing over $10K. I’ve had my transmission cooler line replaced, passenger side lifters replaced, my transmission triple flush with reprogram transmission module. My ‘19 TB is my first truck, so I’m considering other options out there. Just need to do some test driving before my powertrain warranty goes out March ‘25.

subscribing.... I have this with my '19 and dealer fix before. It's out of warranty, it sometimes opens after unlocking from inside or key fob 3-5 times. And sometimes it doesn't open and I just barely pull on it and it releases. Sounds more mechanically on my end is the problem where it's not disengaging. I may try some lube and see if that works.

8-speed, 68K miles.

Initial charge for me was going to be triple flush, reprogram transmission control module, and reprogram ECU for about $1300. Luckily warranty covered everything except the reprogramming which I pretty much had that covered too with my GM rewards for installation of rebuilt GM transmission for my wife's 2016 yukon slt. That's another story.

Was listening to someone couple days ago talking about their issues on their High Country, 6.2L, 10-speed locking out on him numerous times. Dealership could never replicate it. So the fix for him was disconnecting the negative cable for a few minutes and reconnect. It would then get back into gear and start up.

After 2 1/2 weeks in the shop (transmission tech was 2-3 wks out), my shuddering is gone. It was happening every time it gears from 1st-5th from what I could tell. Dealership quoted me around $1300 for triple flush, reprogram transmission module, and reprogram the ECU. I told them it's still under warranty, so service advisor made some calls. Price was going to be around $400 for the reprogramming since it's not covered plus my oil change and tires rotated. Final cost $41 for triple flush, reprogramming, oil change and tire rotation. Used my $230 rewards from my wife's yukon transmission that went out on us driving back from vacation 10 hours away. $7100 for transmission and service advisor over charge some. So far the shifts are great! Hoping it doesn't happen again and will keep an eye out for it. Before the warranty runs out, I'll probably sell or trade in for something else.

They do come in threes, that's for sure! Once it's ready, I'll have to fly there, pick it up and head on back. I do keeps files/folders on all my rides for service done or parts bought for them. I'll just try to keep her going until we decide to sell/trade-in.

Had our family vacation in which we just arrived home at 1am this morning in a rental. From Anaheim, CA (Disneyland) to Lubbock, TX (home) it gave out in Tucson, AZ. Slipping so bad rpms jumping to 3K and barely moving, Trans Temp 198. Dropped it off at Watson Cheverolet there in Tucson. Service guy called me on the road and no codes were pulling up, but his transmission tech says something is definitely wrong internally. Looking at a little over $7K for a GM rebuilt transmission with 3 year/100K mile warranty which includes parts and labor. The most expensive vacation we ever had. Wifes ride is 2016 Yukon SLT, 2wd, 5.3L w/ 120K miles. Oil changes religiously, trans flushed about 40K miles ago, I just did brake pads replacement, A/C condenser replacement. Think the 110-114* was just too much for it had we counted about 30 vehicles on side of road (most blown tires, others engine/transmission problems likely). Parents Acadia engine went out, had it replace with rebuilt for $10K, my TrailBoss trans cooler line leaked(replaced under warranty), Passenger lifter failure (replaced under warranty), and now has a shuddering in the transmission, and now wife's Yukon transmission failure... Thoughts, suggestions? Wife wanting to switch brands and I'm on the fence.

She's REDdy

Been a little over a year and it's still holding up. Had a few physicians and pharmacist at work with newer '19-up GM vehicles having problems with lifter failure. No transmission oil lines yet, and hope not.

I hear ya! Did the same thing.
