Replacing the filter on an A40-series automatic transmission is one of the most direct ways to protect the hydraulic circuits from accumulated debris, and this single filter covers a wide range of units in that family. CFI-005811 is listed for A40, A40D, A41D, A42D, A43D, A44D, A45D, A46D, AW70, and AW71 transmissions, with application starting in 1981 and continuing through current production.This is a one-piece listing: you receive exactly one filter, nothing else. There is no gasket included, no drain plug seal, no hardware. If your service job requires those parts, they need to be sourced separately. Knowing that up front saves time on both ends.The filter housing and inlet dimensions are matched to the original specification for these units, so installation follows the factory procedure without adaptation.
