    Broken door handle. I hate theives.

    Yeah. When I got my Denali ,the key hole was already tampered with. Key didn't work. Then they finally broke it that last time. So I just figured to put a rear handle. I also removed the metal bar that unlocks the door.

    Atf in fuel tank to clean injectors.

    Well fellas did another run to big bear. Filled up the tank and added Lucas upper cylinder cleaner. 3oz per 10 gallons. On the freeway where it was flat. The Denali was staying at around 19-20 mpg. Doing about 65-70mph on cruise control. Not bad for an old girl.

    Atf in fuel tank to clean injectors.

    Hey fellas . Have any of you guys done this before. A old school mechanic told me to do this years ago. I have done it on many of my other cars, but haven't done it to my Denali. Old school mechanic explained that atf is like a solvent cleaner and helps carbs and injector.

    Automatic Transmission - slight surge from 1st to 2nd

    I recently did a fluid flush thru the radiator cooling line. I thought it changed most of the fluid, but I was wrong. I recently had a check engine light about a shift solenoid. So I took the pan down and replaced both solenoids and filter. Let me tell you that the fluid was still pretty...

    Stock 17's to 20inch rims mpg difference

    Makes sense. I'm pretty sure the 20 inch rims on my truck are pretty heavy. And for sure the tire is wider. So I think I'm going to start with going back to 17's and getting the correct tire width. I just reached out to black bear performance about a tune. But living in California I don't...
