What did you do to your NBS GMT800 Tahoe/Yukon Today?

[NCTyphoonKid]

Got into a bump up on Friday and changed out the whole front bumper assembly on Saturday and today I did a tire rotation and finally installed the correct lug nuts for my PPV wheels

 

[Tonyrodz]

Did the 4hi mod in preparation for my retrofit. I followed this walk through and it was super easy and best of all free!

Love the PPV wheels

Starter had been acting up. Had plans to replace it tomorrow when I was off, but the truck had other plans.

Got the old one out before work, gotta put the new one in once I get home.

Discovered I most likely have a rear main seal leak, in addition to losing coolant somewhere, and a leak at the brake booster.


Good news: found a 6.0 with a 80e attached, and a machine shop that’s willing to cam it and bore it over to 6.7L. So... that’s the new plan.

This is the second time it’s been towed, first was after an accident. Both times the driver has said “that’s a damn good looking Tahoe”

Wait, so why did you tow it?

Couldn't agree more!

Wouldn’t start. Been able to beat on the starter before and get it to go, but no luck today. Was locked down.

Finally got to the trans fluid and filter change. AC Delco Dexron VI from Amazon. AC Delco filter and seal #24208576 (I didn't use the pan gasket).

Fluid was DARK.

I did remove the linkage bracket (driver side, T40 torx) and the heat shield (passenger side, 10mm). Pan came down easy peasy. No prying, pulling, or anything. Just the right angle and down it came.
Pretty good bit of sludge on the magnet, but no shards or chunks...

All cleaned up and Lubelocker gasket...

The filter seal was hard to get out, but I managed to get an edge bent away and got ahold of it with a little pliers.

Since BlackBear is in two weeks and I had the fluid out, I decided to make a day of it. You guessed it, Vette servo! Followed this:

Went as planned. I didn't get any pics of this because it was getting dark and started raining. I was going as fast as I could while still respecting the fact that I was working on my transmission. Getting the snap ring back in sucks.

Finished the flush and used the stick to get the level close. I put it through all the gears in idle and double checked. Then I took it around the block a few times. 1-2 shift is nice. With the little sprinkle going, it even got loose for a sec at WOT. Sweet. So far so good.

Got home, put it through the gears in idle again, rechecked the fluid level, and topped it off. Will check hot again tomorrow. Follow up later.

Whoa, Mister Accomplishment lol. That’s quite a bit of work. Good job.

Ummm, yes.

Hey they missed those things on your exhaust that aren’t on your exhaust...

Man! I'd love to do that swap. Hoping you get it! Would be an awesome build thread.
