How much fluid goes into the front and rear differential?If your going to change your trans filter, you should also drain the trans fluid in the pan via the drain plug. Once the new filter (dont forget the magnet) and plug are reinstalled, you can add 7 quarts to the trans through the dip stick tube. Use a funnel. After the trans fluid is added, start the truck and check for leaks. Let the trans warm up and check fluid level on dipstick. You may have to add half a quart more. MAKE SURE YOU USE DEXRON VI TRANSMISSION FLUID. The 06 Ali 6 speed comes with DEXRON VI from the factory. DEXRON III will work and some dealerships don't no the difference and are mixing fluids. DEXRON VI is slightly more acidic than DEXRON III. 05 and older Allisons use DEXRON III but I wouldn't risk it, especially if you make a warranty claim and they use that as their arguement.
I run 15W/40 Dino oil in the summer and 0W/40 synthetic in the winter. When my DIC indicates 50% fuel filter and or oil filter life, I change them. I also just changed front and rear diff oils and used 75W90 Synthetic. Both are easy to change...front diff has a drain plug on the lower (drivers) side of the diff and a larger filler plug above it. Use a syphon pump to fill. The rear diff has a drain plug at the bottom 3/8 ratchet will remove it, fill from the side level plug.
