Allison spin on filter?

[Mustfish]

When I bought my 2002 truck, a friend who also has a D/A truck told me to change the spin on transmission filter every 3k miles or so. The only thing I have seen is to change the fluid and filter every 25k miles. How often do you guys change the spin on filter?

Go to the "search" function for 2500HD/3500 HD Trucks & Drivetrain. Use keywords "spin on filter", there are numerous posts about this topic. You should find what you are looking for.

Change the filter once at 5k, then again every 25k.
