Fitment gate — this filter is selected by transmission, not by vehicle. Confirm your transmission is an Allison 1000, 2000 or 2400 series LCT with a shallow pan before ordering. Deep-pan applications take a different filter.

Second fitment gate — the pan gasket is not included. Dropping the pan destroys the existing gasket, so order a gasket with this filter or order Baldwin 20016, which is the same filter supplied with one.
