F 550 4WD Super Duty V8-6.4L DSL Turbo (2008)
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.
1. Lubricate the O-ring seal with clean automatic transmission fluid and install a new TFT sensor. Make sure to slightly rotate the sensor to lock it in
place.
