Review on ATP B 343 Automatic Transmission Filter by Darrius Frison

Unfortunately the transmission filter set does not contain the correct parts to replace the transmission filter on a ZF 4HP18 or any variation of this transmission. The kit comes with a filter and valve body gasket, which are not related to the filter change. To be useful, the kit requires the correct o-ring for the transmission filter cap, not the valve body gasket (which is located on top of the transmission). The filter appears to be of standard quality, however I would recommend a kit that comes with the correct parts.
