I have no idea....Black02Silverado could probably answer the spec stuff better. What I do know is my 8 speed had been flushed 3 times with the “new” mobil 1 stuff and all of its bad manners returned after about 3 thousand miles each time.I finally found a dealer that was useful and they did a quick re learn and then I had the fluids swapped and it worked for me. Before doing this it was embarrassing to have passengers because it sounded like the transmission fell out every time I slowed down to a stop.

Flush with Amsoil ATF, worked wonders for mine. Still get the clunk on the initial start and takeoff but it the clunks have been 90 percent eliminated.

Ahh just a creative bump for a good cover.....have the X2 on my 17 for over 4 years now and its been a great cover good luck selling.

Seriously? Never heard the Warrant Officer insignia being called a squash bug?

Squash Bug sighting!

The Amsoil ATF really helped mine alot. Had the tsb done 3 different times and finally pulled the trigger on Amsoil and did a complete flush. I also replace the tc and plan on doing both diffs in the future. My recommendation would be having the dealer do a quick learn as well.

Are your rpms fluctuating while the truck vibrates? The flush fixes that but if your still getting a slight vibration and clunk you could try a flush with amsoil atf. Thats what I did with mine and it has worked wonders so far.

Mine doesn't seem to do that. It does have a little float on the highway which I like, really makes for a smooth ride and then tightens up going around turns. Maybe thats what your experiencing? The magnetic ride isn't for everyone but I really like it. How many miles are on it? Check and make sure the shocks aren't leaking.

I have had mine drained and replaced 4 times and the shudder always returns after about ten thousand miles. I am about to replace with AMSOIL and add 20 ounces of the shudderguard additive below. I will let everyone know if it helps. Mine only has a very slight shudder around 80 mph when cruising. Its seems that the shudder guard is added protection and I am more curious than anything. A dealer in KY did a quick relearn on my 8 speed and it really helped the 1-2 bang shift so if I can just get the shudder fixed I will be thrilled. GM-8-speed-shudder-flyer_all_sizes_2.pdf

That 10 inch looks good. I thought about doing something similar but got scared off by the active noise canceling in the 6.2 and the factory bose sounds pretty decent.

Same guy gave us all grief for trying to get the dealer to fix our clunky leafs and then makes a post asking about part numbers when he takes his to the dealer for...............you guessed it clunking leafs. As far as the 8 speeds, thats the first I have heard of complete failure like that, maybe you can get some help from GM since they know these trannys have alot of known issues.

I have for sale a device that allows you to mirror your iphone and use video in motion (for offroad use only of course) in your 2017-19 Sierra. It should work in the Silverado as well, the device is from MVI inc and they are awesome to work with. I am looking for more functionality so I thought I would throw this one up on here. It works great for mirroring hulu, youtube, prime video and the only issue it has is with netflix. You have to download the content and then view it for netflix. It comes with all connections needed for any iPhone with lightning cables. I cannot verify anything with an

Came across this, let guys that are smarter than me make recommendations. I have a 2005 Accord with 178,000 miles on it and used this stuff and it worked great haha. GM-8-speed-shudder-flyer_all_sizes_2.pdf

No I don’t, took mine in for the coasting clunk and they told me there was an ECU update that they completed and it really helped.

There is an ECU update that I had done to mine today that makes it run muuuucccchhhhh better. I had a hypertech tune on mine that I will not be reinstalling. They also did a fastlearn on my transmission that killed the coasting clunk too.
