Allison High Efficiency Filters

Allison Transmission has introduced a line of high capacity filters that can, if used along with an Allison approved synthetic automatic transmission fluid, allow owners to extend their fluid change intervals. (Click here to go to Allison's website for a list of currently Allison Approved TES 295 automatic transmission fluids.) 

Transmissions built with the new filters do not require an initial Main Filter change at 5,000 miles/200 hours.

The new filters were introduced over the last couple of years and there is no clear manufacturing date to tell if your Allison Transmission has the new high capacity filters.  If you have a 3000 series transmission, serial number 6510670912 or higher, or a 4000 series transmission, serial number, 6610205144 or higher, then you should have the new filters.  A general rule would be if your FCCC chassis was built after September 1, 2006 then you have the new high capacity filters installed.
