strutaeng's 04 2500 4x4 project Suburban

I got the Smurf blue stuff in the mail today. I filled the TC by sticking a 3' piece of clear vinyl tubing and put a funnel and filled it off to the side, above fill hole level. Of course, I overfilled it and spilled some on the ground. Doh!

I also drained the front differential. The magnetic drain bolt had a TON of residue. IDK if this had ever been replaced TBH. Refilling that was also the same way with the tubing and funnel, but much easier because you can route the tubing through the front wheel and keep an eye of the fill hole. I had a drain pan under it, which I should have done when I was filling the TC...

I also put fresh ATF Dex VI. Shifted through the transmission gears and the TC gears. Everything seems good.

I love the elevated funnel method, especially on thick fluids like gear oil that are cold! Fill up the funnel, walk away, refill every so often as you tinker on something else or clean up.
