Did you rub Vaseline on your camera lens or do you just have an IPhone?...

Changed the rear diff fluid earlier. So far this has been my least favorite job - I'd rather do the spark plugs again. Forgot to drop the spare tire which wasn't an issue until I had to refill the oil. My harbor freight transfer pump had kicked the bucket on the front diff (which was its first use) so I had to refill by hand.

Didn't have much room to hold the bottle directly against the fill hole, so my solution was to add a foot of vinyl tubing and angle it up between the spare and the rear quarter panel. This worked ok but the hose slipped out once and left a mess on the driveway. Should've put cardboard down, but oh well.

That sure beats wearing that stuff. Especially when it’s worn down your entire sleeve and inside your the rubber gloves you have on. Smells delicious and doesn’t seem to wash off for months. Buy yourself the Lisle transfer pump and/or the fluid pump designed to screw onto the top of gear oil bottles. Don’t buy the cheap one...if you want to know why (see the first part of this message).

When you change your transmission fluid it should be all black and sparkly looking correct? Ha! Holy smokes was I shocked and disappointed in waiting this long. Hell, You could mix the gear oil from either differential together with the Mobil 1 5W30 inside the oil filter and still pour out a cleaner, more clear liquid than the $hit I just sucked out of my transmission. Now I’m scared to drop the pan, but I know my Denali will thank me when I’m done.

*FYI: I did have a broken trans dipstick tube so how much of that dark tint is the result of dust and dirt from the roads?




Here is proof to any of the new owners or young guys out there who might consider “nah ill get to it later”, or “it can wait until the weather warms up”. Nope! I’m sure glad that I didn’t wait any longer on this fluid/filter change.

Hopefully your trans is ok.

I’ll take my iPhone over a spy-bot google tracking android device any day of the week. And any of you guys with the Facebook app or google chrome on your smart phones...just burn them.

Yeh I sure hope so. I haven’t fully dropped the pan yet. Temps are supposed to be a realfeel of 24* tonight and since it’s currently only about 45 degrees in my barn, I decided to take a break for now.

Can rpo code UFT be added to my truck? Found a set of mirrors I’d like to use but have DL3 and UFT. Hope I can use them.

Your weather is slowly creeping this way. Winter is coming!
