What is the Allison 3000 Series?
Allison describes the 3000 Series as a commercial-vehicle transmission family developed for medium-duty applications. It is a separate family from the lighter 1000/2000 and heavier 4000 offerings. The full model and application suffix determine what a particular unit supports.
What matters in a comparison
A 3000 Series comparison should include the truck’s engine, body equipment and operating pattern. Ask which vocation package and control generation are installed, and whether PTO or other body functions are configured. Check service records against the correct application. Frequent starts or stationary equipment operation should be reflected in the ownership discussion, rather than relying only on distance travelled.
Fluids & filters
Commercial on-highway Allison 3000 Series; sump dimensions must be identified before ordering.

A catalogue cross-reference links part numbers. It does not confirm that either part fits every version of this model. Match the original part to the unit first, then check the replacement manufacturer's application and any supersession.
Main/lube high-capacity service filter kit
3000 Series 2-inch or 7-inch sump; kit contains 4-inch service filters. Verify the OE kit against the serial number. Catalogue cross-reference does not establish approval for Prognostics, extended intervals or Allison Extended Coverage; those require Genuine Allison filters.

What still needs unit-specific confirmation
- Sump and service-filter lengths are different measurements. A family name alone cannot select between the two kits.
- Internal suction-filter parts require the exact transmission service catalogue.
