Rear Servo And Rear Band; Torque Converter Service - Jeep J-10 Series 1982 Technical & Service Manual

2C-62 AUTOMATIC TRANSMISSION
inspect the bore in the piston and the piston rod O-ring
(fig. 2C-92).
Inspect the band lining for a poor bond to the band,
burn marks, glazing, uneven wear pattern and flaking.
If the lining is so badly worn that the grooves are not
visible at any portion of the band, replace the band.
Inspect the band for distortion or cracked ends. Replace
as necessary.
Assembly
CAUTION: Do not use force to assemble any of the
servo components. If they do not assemble easily, in
vestigate and correct the cause before proceeding with
assembly.
(1) Apply petroleum jelly to piston rod O-ring and
install piston rod in servo piston bore.
(2) Install piston rod spring on piston rod.
(3) Install washer.
(4) Compress spring and install piston rod retaining
snap ring.
Rear Servo and Rear Band
Disassembly
(1) Compress piston plug spring and remove snap
ring.
(2) Remove snap ring, piston plug, and plug spring
(fig. 2C-93).

Inspection
Inspect the piston and piston plug for nicks, burrs,
scores, and wear. The plug must move freely in the
piston. Inspect the piston bore in the case for scores or
other damage. Inspect the springs for distortion.
Inspect the band lining for poor bonding to the band
and for excessive wear. If the lining is so excessively
worn that the grooves are not visible at any portion of
the band, replace the band. Inspect the band for dis
tortion or cracks and replace as necessary.
Assembly
(1) Lubricate piston plug and piston with petroleum
jelly and insert piston plug through plug spring and into
piston.
(2) Compress piston spring and install snap ring.
Torque Converter Service
If the transmission is being overhauled to correct a
malfunction that generated sludge or heavy accumula
tions of metal particles or friction material, the oil
cooler and cooler lines must be flushed thoroughly and
the torque converter replaced. Do not attempt to clean
or flush the converter.
The oil cooler and cooler lines can be flushed using
solvent and compressed air.
Flushing Oil Cooler and Cooler Lines
(1) Place length of hose over cooler outlet line and
secure end of hose in waste container.
(2) Place length of hose over cooler inlet line.
(3) Pump approximately one pint (0.47 liter) clean
ing solvent into oil cooler through hose attached to inlet
line.
(4) Insert compressed air gun nozzle into hose at
tached to cooler inlet line. Apply short blasts of com
pressed air to flush dirt and solvent from cooler and
lines. Repeat flushing operation until drained fluid is
clear.
(5) Pump approximately one pint (0.47 liter) of new
transmission fluid into cooler and lines. Repeat flushing
operation, using new transmisson fluid, to remove all
traces of cleaning solvent and any residual dirt.
(6) Remove hoses from cooler lines when flushing
operations are completed.
TRANSMISSION ASSEMBLY
NOTE: Use automatic transmission fluid or petroleu m
jelly only to lubricate transmission components during
assembly.
Overrunning Clutch
(1) Place transmission case in upright position and
install clutch cam and spring retainer.
(2) Install clutch springs and rollers so springs rest
against retainer post and rollers rest against springs,
and with both springs and rollers installed on counter
clockwise side of spring retainer posts (fig. 2C-94).
