DESCRIPTION
Located on each side of the top of the converter housing are identical two-element filter assemblies. The right-side assembly
filters all the oil pumped by the input-pressure oil pump that is located immediately below the filter cavity in the converter
housing. The left-side assembly filters all oil returning from the torque converter before distribution to the lubrication system.
Each filter assembly consists of a head assembly and two element assemblies. Each head assembly consists of a head, relief
valve, two springs, a valve seat, and a snap ring. Each filter element is replaceable as a unit.
The filter assemblies are bolted vertically into the converter housing cavities. Oil to be filtered is pumped into the cavities
surrounding the filters. The filter elements are hollow disks of fine mesh wire screen. Oil flows into the elements and into the
perforated tube on which the elements are stacked. Foreign matter in the oil collects on the outer surfaces of the filter elements.
Filtered oil flows up the perforated tubes, through the filter heads, and into the converter housing. Should the filter packs become
clogged, pressure in the filter cavities will rise until the relief valves open. When the relief valves open, oil flows directly into
the hydraulic system.
Removal
1.
Remove transmission oil filters in accordance with TM 9-2350-256-20.
