Tranny fluid change
Got 70,000 miles on the current ATF oil, so today it and the spin-on filter got changed. I also dropped the pan to see if there was any sludge and it was clean. Love this Duramax/Allison combo.

For those unaware, it is not. It is a personal preference.

By having to change the transmission fluid every 30k miles you're essentially doing a fluid exchange.
Sure glad I don't have to worry about having to perform that job every 30k miles IMHO.
The 30K is simple drain and fill, about 7 qt. Aisin states Mobil 3309 which a case of 6 is about $30, MOPAR labeled is like $60 a gallon.
60K a little more involved, drop pan and change filter, also send sample to Blackstone for lab work.

The "YET" part is what scares me. If the filter says tighten a certain amount after contact I do so. Honestly if a filter can be removed by hand after 5-15,000 miles that is loose IMHO.
Ron, tighten by hand the 3/4 turn past gasket contact, it is tight. I didn’t say it spun off easily at change. I wear a playtex rubber kitchen glove for heat resistance and better grip. I have been doing this way since an oil and filter change on Dad’s 59 Ford 352. Destroyed the spin on filter getting it off had gone on with clean oil on the gasket, and likely a full turn after gasket contact, that was about 1967,!
The 2001 ran 10k between changes.
Some filters say 3/4 and some 1-1/4 past. Diesels seem to have more vibration.
Fleetguard states 3/4 never had a problem, my 2001, DD 2004 3500 DRW, or the 2016 3500 DRW. As stated it take grip and some twist to get off, but don’t need to fiddle with a filter wrench or strap wrench.
