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.

What about all the "OLD" ATF left in the converter???
You'll never get all the oil out, even by a professional shop
Next time someone drops their oil pan, best to install an oil pan drain plug. Much easier for the next oil change.
allison already has a drain plug. no need to add one.
