Has anyone every installed an inline oil filter to their transmissions which might help improve transmissions fail rates

-- Inline ATX Oil Filter
The mesh filter on the 4EAT ATX oil pan filters only to 200 microns. Inline ATX-specific filters can be fitted which filter down to 50-10 microns and so remove abrasive clutch material as it occurs rather than circulating it around torque-convertor, clutches, valve-body, oil pump. Traditional "spin-on filters" & adapters are available.
The CD4E transmission has a filter, but it is embedded deep inside the transmission for some reason known only to Ford. Thus it is very advisable to buy an external inline oil filter (eg,
www.permacool.com) and do a complete fluid change annually. The transmissions are rated only slightly above the US AXOD Taurus transmissions, and so the use of cheapest-brand full-synthetic annually may be advisable since some problems are as much design as overheating related.
