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.

"Yes you can. Fill the transmission up, according to the dipstick, remove the return line from the oil cooler, install hose fitting, start truck, pump out a gallon, refill repeat until nice clean fluid appears."
BINGO......We have a winner!!!!!!!
To make it easier check fluid level before starting job. Measure amount removed from pan and replace the same volume then do the start run and refill exactly what has been pumped out.
