Throwback to the time an 8-year-old saved the shop. Little dude's like a superhero — he grabbed the pressure washer and fought back that fire for 2 minutes until Taylor came to get me. Barefoot too. Guess those tires were too close to the burn barrel. Get that kid a firefighter hat.

Your 6L80 doesn't have a transmission dipstick.

Checking the level the right way means the truck on a lift, the fluid at the right temperature, and the check plug pulled. "Just top it off" usually means a guess.

If your truck started shifting strange after someone added fluid, or you can't remember the last time anyone checked it, give us a call: 386-400-3920.
