Yeah but do they fold?!

If I pull them in by hand they will.

Made arrangements to pick it up. It's ~700 miles away, and I had a friend check it out for me, this morning. It'll be my first GMT-800, an 06 Yukon Denali.

Dammit! Any voltage testing to the motors done today?

 

[Sam Harris]

Drain / Filter / Fill the Transmission, as well as the vette servo and longer servo pin installed. Very happy with the change. Not much different driveability, unless you get your foot in it, and then you can really tell the difference. Much faster shift, and happy to have nice, clean fluid and filter. Sorry no pics. Fail.

I can’t comment on just the vette servo as I had a shift kit and some other things done, but it definitely makes a difference in shifts at moderate to full throttle. Probably my favorite thing about driving the burb

Nope. All I have is a continuity tester, but I didn't know what the pinouts were, so I just said screw it and bolted them on. Once or twice it seemed like the driver side was gonna fold. Hitting the switch to close them, ds mirror went down, but that was it, nothing more.

Curiouser and curiouser... wonder if there's a loose connection at the fold motor.

Wish I knew. Both tho.....

Interesting! So it’s moving the mirrors down, when you push it inboard..? That’s step one, before they fold in..! Sounds like the fold motor doesn’t have power or ground.

Turn signals look good. [emoji106] Man, really need to replace my stock tails.

 

[ScottyBoy]

Tony, I used to have the pinouts saved on my old computer before it crashed. I know for a fact that the fold wires are a gray wire and a brown wire. I can't remember which one is which. But when voltage is applied to those two wires, the mirrors will either fold or unfold. Reverse the polarity on those wires and the mirror will move the opposite direction (fold or unfold).

Humph f me it was a hard day. Doing this shit in my driveway is torture. Especially for an old man. Gettin too old for this.

Thx. I hated my stock tails. Was my 1st mod.

Thx Scotty. Can't wait to give that a shot. Are those wires in the black connector? Power to one and ground to the other? Good to see you back buddy

What'd you find Mark?

That's what I'm thinkin.

Nothing obvious. Transfer case seems ok, torque converter looks ok, trans looks ok with no oil leaking from the front seal. But if I put the gear selector in N the tail shaft only turns in one direction. When it happened, at first the truck felt like the brakes were on then it killed the engine and the starter wouldn’t turn it over. After it sat for about an hour I was able to start the engine and I was able to move forward a few feet but not reverse. And when the tow truck came, I tried pushing it forward and back in N with the engine running and not running. I could only move it forward, it wouldn’t go back at all.( I warned the driver but he loaded it on a flatbed and there’s a whole other story in my build thread about getting it off that truck.) So something was locked up and it looks like it was the trans. I’ll get a warranty authorization and ship it and the converter back to see what they find.

Hopefully they won't bust your chops and replace it.

Oh wow.... does it have a trans brake?
