(1)
Using spring compressor J24219, depress the main pressure regulator valve spring. Remove the snap ring
(1).
NOTE
The spring compressor may be used whether the front support assembly is attached to or removed from
the torque converter housing.
(2) Remove the spring compressor, and remove washer (2), valve stop (3), spring (4), and main pressure valve
(5).
(3) Using the spring compressor, remove snap ring (6), washer (7), valve stop (8), spring (9), and lockup shift
valve (10).
(4) The spring compressor is not required for the remaining valve components. Push inward against valve
support assembly (11), and remove snap ring (12). Remove support assembly (11), seat (13) converter
bypass valve (14), and spring (15).
(5) Remove the nineteen bolts (16) remaining in the front support assembly. Lift off the front support assembly
(17) and gasket (18).
(6) If replacement is necessary, remove the needle bearing (19) from the bore of the support hub. Special tool
J28557 may be used to remove the needle bearing.
NOTE
Do not attempt this rework procedure unless adequate machining capabilities are available.
(7) Determine the serviceability of the seal ring grooves on the front support hub. Insert, without force, gage
J29198-3 into a groove on the support hub. Rotate the gage 360 deg. around the hub.
(8) If the gage does not rotate freely, the support is damaged and should be replaced or reworked.
NOTE
A damaged or worn front support hub can be salvaged with guidance from the instructions on the
instruction sheet in the sleeve and pin kit. The kit contains one unfinished front support sleeve, one
sleeve retainer pin and one machining and installation instruction sheet. Kit P/N 23011446 (21).
If there is evidence of movement or damage to the ground sleeve, replace the front support
and sleeve as an assembly.
(9) If the needle bearing (19) was removed from the front support, install a new bearing. Installer J24197 may be
used with handle J8092 for driving the bearing, or without the handle when press-installing the bearing. Drive
or press on the numbered side of the bearing until installer bottoms on housing for proper bearing depth.
