I use to work with a person who use to work at an Allison transmission place.. He was more of the behind the desk guy at that place. And I know someone who rebuilds Allison transmissions for a living. They don’t know each other but they both agree you don’t have to ever do the internal filter on the Allison unless you do a rebuild. That’s how they designed it. You have the outer filter and a drain plug. Don’t open up anything. Even if you’re doing heavy stuff. Just change the fluid and filter more

[@YaBoyMike]

Thanks for making the video, very informative. One note I wanted to add is that manually selecting the gears doesn’t actually engage them. It only limits the transmission on the highest gear that it will shift into.

[@ralfie8801]

Just so you’ll know, that was probably the original fluid fill from the factory. I just pulled the pan off of mine yesterday to put a deep pan on it while I was changing the leaky cooler lines and putting a bigger cooler in the grille. I bought the truck new, and yesterday is the first time the fluid has ever been drained and changed. The truck is a 2007 K-2500 Classic, the inside of the pan wasn’t any dirtier than yours was with the fluid being just a bit darker than yours. I have changed to spin-on filter every 25 - 50K miles with an Allison brand filter every time except once. But I have to admit, you lost me when you put a filter wrench on it to tighten a filter that is only supposed to be hand tight. That is exactly why you had a hard time removing the old filter. Never ever, even less than that, tighten any spin-on filter with a filter wrench, hand tighten only. Allison recommends only changing the internal filter at overhaul time, even though they chose to put a reusable pan gasket on it to save you $40 or $50 on a new gasket. Obviously that’s out the window if you decide to put a deep pan on it like I did. You can do what you want though, it’s yours.

[@shaunwhetten3452]

Draining the transmission fluid through the drain plug vs. dropping the pan should make little difference in the amount of oil that is changed. The reason people drain change the oil, refill, drive a few hundred miles, and then change it again is because that way it flushes the oil in the torque converter.... Not to flush more oil out of the pan.

[@peterssynthetics-independe6786]

It is better to do a flush with disconnecting the transmission cooler return and crank the truck.

I tinker and want to try save him a buck. No complaint of steering issue. I felt underside at Master /booster union and feel minimal fluid. No puddle or honest trace of a external leak. I jumped in truck, hit brake pedal- to floor. I let truck run a bit then shut off - pedal to floor. I held foot on pedal and started - no build up. If I take foot off- pedal will return out. I have not worked on a hydr, just the old canister suction type. On another vid it was concluded a ABS pump was the prob on a like issue.

[@rileyeitel4724]

Allison repair and service says you do not change internal filter unless you are rebuilding the unit that is why they put on an external filter. That external filter runs straight into your pump. Allison’s are designed in a way that you change the oil in them like you do motor oil. Drain remove filter install new filter and fill. It can actually do more harm then good to change internal all the time. The wore down clutch material in the oil helps worn clutches to grab better when worn down

Mine had 90 thousand before a fluid and internal filter change and the truck has towed heavy since new. My pan was cleaner than that and have only changed the external filter at every 30 thousand miles.

[@white24valve]

It is always a good idea( how I always do it and have done it) is after what you did..drive it for the 100 to 200 miles...and then do that again,because the first time you do the trans fluid change..the converter still has old fluid it. Not very many folks think of this.Costly yes..time,consuming yes..well worth it...and I change all the filters and drop the pan..everything times 2!

The second change out is in theory, changing 50pct of the 'new' fluid you just put in.'

There’s no need to drop the pan. The internal filter is to be changed upon rebuild. It’s more of a strainer than a filter. The external filter is plenty.

A little warning for those that are doing this for the first time. In a stroke of engineering genius (not) the drain plug boss is about 3/4" above the bottom of the pan. When the fluid stops draining there is still a couple quarts in the pan. You have to carefully lower the pan and dump the rest into another receptacle. Or accidently drop the pan and you can clean up the fluid with speedi dry.

Filter wrenches are for loosening filters only. I’ve heard a full turn past when the seal hits sealing surface. I always just crank on the filter as much as I can just with my hands. But using a filter wrench on a new filter may damage it. But at the very least you will have a hard time changing it next time.

My local Allison repair facility would charge similar amount, but I found it on the web for under $45/gallon. MadJack Diesel is one source, but I'm sure there are others. Forget Ebay/Amazon- much higher prices.

Always check online; dealers sell for like 25% markup with a smile on their face
