Correct...took mine in today with 22k on a shuddering tranny and no questions asked... Flush and recommendation to monitor for 500 miles and if it happened again then torque converter replacement.

Status report?

GM calls it the Blue Label. It should say that on the invoice when you get that.

Wish this covered the 2016 Canyons too ?

Why? You should not have the problems that 17-up owners have. Yours is covered by a different TSB. TSB #18-NA-145.

It is everyone anymore.

With cutting cost and more and more complex vehicles in a very competitive market they sometimes rush things through for better or worse.

Some MFGs have some less issue as they make such small changes that they perfect. The model but then you end up with a vehicle like a Taco that begins to fall behind.

Also today they can have supplier issues.

Took mine in for an oil change the other day and told them to check the tranny and they performed the TSB no other questions asked. This is at the same dealer I've had issues performing other warranty work before on my last truck.

Here is the TSB that was online

Without making me feel too stupid [emoji4], when it says "VIN S, T" by the Colorado listing what exactly are they talking about? I'm sure it's a digit in the VIN, but which one?

Check it out:

"Dealers should discontinue the use of the black label Mobil 1 Synthetic LV ATF HP fluid. A communication from CCA will be released soon advising dealers of how to dispose of the old product.

The base stock of old fluid (19355656) has the ability to attract low levels of moisture, which can cause degradation of the coefficient of friction of the fluid. The new fluid (19417577) has a new GTL (Gas to Liquid) base stock that is able to tolerate more moisture. Shuddering transmissions and torque converters have been recovered with the new fluid. New transmission fluid tests have been developed due this issue to prevent it from occurring with new transmission fluids."

I wonder if you could safely use the blue label new stuff in the 15-16s. I know we have different issues but, is the fluid better or, just better for the 8 speeds and their issues?

Yes this was what GM started back in Dec.

It was the first admission to what was happening to cause this.

In what I have read on Shudder in the industry it has been moisture from various scourge that cause the issue. Some fluids and even in Audi it was from the transmission coolers in the Radiator.

It appeared logical but till some had it done with good results....

I even read on some gun web sites folks I pushed tranny fluid to prevent rust on guns. Some of the new formulas of other types are attracting moisture and has caused issues according to them.

It used to be simple we had just two main fluids and today look at how many we have.

i find this post very interesting. the main reason i say that is i have a 2019 bison with a June production date. I am not sure if its a shudder so much as the truck under light acceleration feels like it cant figure out what gear to select and a mild "shake" happens. based off of the TSB mine shouldn't have that lol.

 

[1STSFG]

Sounds exactly like one of the symptoms.

You have the new fluid.

As for what you have give it some miles. We all have found with more miles the transmission will fall in line more often. The adaptive programming works but it takes time and miles.
