Installation
Early Build Vehicles With Externally Mounted Remote Filter
CAUTION: Early build vehicles, those equipped with an externally mounted remote filter, are also equipped with a different design sump
filter and bottom pan. Always pair the sump filter with the correct bottom pan design, to avoid cavitation, filter cracking and transmission
damage.
Late Build Vehicles Without Remote Filter and With Serviceable High Efficiency Sump Filter (HESF)
CAUTION: Late build vehicles replace the remote filter with a serviceable high efficiency sump filter (HESF), which requires a wider and
deeper bottom pan. Always pair the sump filter with the correct bottom pan design, to avoid cavitation, filter cracking and transmission
damage.
