2008 Denali Transmission Fluid and Filter Change

[08grey]

Where did you connect to and with what?

That's basically what I did, but I also dropped (well tried to drop) the pan and changed the filter. When I had the pan down, I used a small hand pump and removed the 2-3 qt still in the pan. Here is the Hayden part https://www.amazon.com/Hayden-Autom...a_4?ie=UTF8&psc=1&refRID=NF4W4E9DYQJP01VFYSJG

Hi all, I'm changing the trans fluid and filter in my 2007 yukon denali (100,000 miles) I was wondering if it is a good idea to add the Lucas trans additive while I'm changing it? Thank you

No, GM recommends using 100% Dexron VI. Additives apparently might cause issues.

P.S. I got enough clearance under the Y pipe by placing a 2"x4" above the exhaust, unbolting the transmission, and jacking up the back part of the transmission. This increased clearance between the transmission and the exhaust. The exhaust remained in place but the transmission rose. I then extracted the pan without any cursing.

On a 13 tahoe, I did mine,on hoist,dropped the Y pipe .That was the easiest least messy way. Trans took 4 litres plus with pan off and filter change.Did the transfer case as it has a drain plug.
Changed both differentials lubes at the same time.
