This is why mine has a catch can on it. Keeps that stuff out of the intake.

I have a catch can too that also has the same fluid. I dare you to look in your intake and see if you still have the emulsion.

Yes, go with one with a 6 speed. I own an 09 Tahoe and 06 Sierra Denali, I absolutely hate the 4L65 in comparison to my tuned 6L80. The 6.0 is a great engine, but the transmission kills it. Second gear sucks so bad till the rpm's climb back up, and going 85mph makes it rev a lot more. The 6L80 always knows where the power band is, especially when it's tuned.

I'm not buying it, lol. I love my current Yukon XL 2500, but I do wish it had the 6L80 as opposed to the current 4L80E. Some day I want to send her to Duraburb and get the 6.6L/Allison conversion done. Just need to find $15,000 growing on a tree somewhere... Lmao

you will need the tailgate as well
I thought I only needed the hybrid tailgate if I wanted to run the hybrid spoiler.
