The valve body was replaced under warranty on my 21 5.3 V8 8 speed. The transmission has worked perfect ever since.

Bingo!

Does anyone remember Audie Fulton's Mod Squad?

Excellent comparison Joey.I have a 21 5.3, runs excellent.

I live at the top of a steep hill. In very slick winter storm conditions the 4 lo is a life saver for holding the truck back when descending a steep grade.

Don't waste your money on the Range, mine failed with the Range installed. If you want a Range I will sell you mine for $100.

Check with Diode Dynamics, I have their top of the line clear fog lamps on my 2021 Silverado. These are the best fog lights that I have ever seen and don't blind other drivers. They work great for driving on dark city streets. The only negative is that they are very expansive.

Thats what warrantys are for, see your dealer

Question for bikerjon, what can't you stand about your DFM? I can'f even tell when mine is working. I was using the Range on my 21 5.3 when I had a lifter failure. I am no longer using the Range as I feal it has no benefit and lowers the fuel mileage.

Ceramic is quiter, lasts longer, less visible dusting and longer rotor life. Akebono is a GM supplier and very good.

GM's customer service is not good. The only way that I have got action is through my dealer. I have a very good dealer, Carr Chevrolet in Beaverton, Oregon.

This oil is probably OK, but the current GM spec is Dexos 1, Gen 3. Gen 2 is now obsolete.

Don't expect Bilstein shocks to improve your ride quality as they are very firm. The 20 inch tires are the issue. Replace them with the Z71 18 inch wheels and Michelin Defender tires.

The HD air filter element that come on the Z71 are thicker, but are interchangable with the standard element.

Diode Dynamics top of the line replacement fog lights were a great upgrade for my 21 Silverado. Expensive, but worth it.
