Allison Transmission Service Fluid/Filters Freightliner or International, box truck

[@Twinturbocamaro511]

What's the part number for the internal filter?

[@izh6421]

Don’t you have to replace a new gasket?

[@boxtrucktriptips8689]

@izh6421 If no leaks or damage, not necessary.

Cada cuántas millas se le cambia el aceite a la transmisión

[@rigobertoespinoza1685]

Every how many miles do you change the inner filter? I want to do a fluid change on my own truck but im scared too. I do the oil changes already heard it not ideal to flush a transmisson. Just change outter filter and drain. My truck has 150k miles.

EVERY FLUID WILL EVENTUALLY GET DIRTY, DEALERS WILL SOMETIMES SAY YOU DONT NEED TO CHANGE FOR THE LIFE OF THE VEHICLE MEANING THIER WARRANTY, ONCE THATS UP NOT THEIR PROBLEM. SO ALWAYS CHANGE FLUIDS, I THINK YOU SHOULD BE OK WITH THE MILLAGE YOU HAVE.

@@boxtrucktriptips8689 yeah had it serviced twice once at 60k and 120k want to start changing ever 30k what you think

[@boxtrucktriptips8689]

@rigobertoespinoza1685 I think that's excessive, what you been doing is ok or even stretched out a little more should be fine. I just changed my external filter and the fluid still looks good and it has been 50k. I will probably change the fluid after another 50k so will change the fluid after 100k.

Hello! Does this also apply to my 1999 Freightliner mt45 fed ex truck?

[@skid3339]

How many gallons did you get once you drained it ?

[@boxtrucktriptips8689]

About 2.5 gallons, just measure what came out and put that amount. Otherwise 3 gallons is what's recommended.

[@jessereagan2340]

You should have shown the actual removal of the filter. You just showed after it was done and put on.

[@boxtrucktriptips8689]

My bad, it literally pops right off and on.
