yeah, just took a look. no option for module setup under tcm. Just the trans daps relearn stuff it says to do after a rebuild. I'll leave that alone.

probably a hybrid thing. I looked everywhere else I could think of and nothing.


so that doesn't mean the dongle can't do it, just that I can't find it on this thing.

Spent my New Years Eve at the shop with my truck. Wanted to use the flat floor to get some vehicle height and camber measurements and rotate my tires and inspect things whilst doing so. Finally found that rattle that has been driving me nuts for months. At least I hope so anyway. I have been under the rear of this thing several times trying to find it. Don't know how I missed it. Hoping I have a nut that fit's it in my "Tahoe" fasteners bucket to fix it today.

Thinking about lowering the rear another inch or 2. And get rid of this stupid Chevy lean sh*t. So I took some measurements at: Front fenders, running boards, rear fenders, rear bumper lip.

Then camber measurements are whacked, no way this floor is level flat, probably sloped flat. I zero'd out the camber gauge on the r/r wheel and worked my way around. Usually I zero it out on each rear wheel and then measure the fronts.


And I measured rear axle to frame clearances at the bump stop mounts.

1/8"-1/4" isn't much of a "Chevy lean", If I'm reading your chicken scratch right, lol
