Hydraulic System (cont'd)
NOTES
A
See flushing procedure, page 14-264 and 265,
B Set idle rpm in gear to specified idle speed. If still no good, adjust motor mounts as outlined in engine
section of this manual.
C If the large clutch piston O· ring is broken, inspect the piston groove for rough machining.
D
If the clutch pack is seized or is excessively worn, inspect the other clutches for wear, and check the orifice
control valves, CPC valve, and linear solenoid for free movement.
E If the linear solenoid is stuck, inspect the clutches for wear.
G If the '-2 shift va lve is stuck closed, the transmission will not upshift. If stuck open, the transmission has
no 1st gear.
H If the 2nd orifice control valve is stuck, inspect the 2nd and 3rd clutch packs for wear.
I
If the 3-4 orifice control va lve is stuck, inspect the 3rd and 4th clutch pa cks fo r wear.
J If the clutch pressure control valve is stuck closed, the transmission will not shift out of 1st gear.
K Improper alignment of main va lve body and torque converter housing may cause ATF pump seizure. The
symptoms are mostly an rpm-related ticking noise or a high-pitched squeak.
L If the ATF strainer is clogged with particles of steel or aluminum, inspect the ATF pump and differential
pinion shaft. If both are OK and no cause for the contamination is found , replace t he torque co nverter.
M If the 1st clutch feed pipe guide in the end cover is scored by the ma inshaft, inspect the ball bearing for
excessive movement in th e transmission housing. If OK, replace the end cover as it is dented. The O-ring
under the guide is probably worn .
N • Replace the mainshaft if the bushing for the 4th feed pipe is loose or damaged, If the 4th feed pipe is dam-
aged or out of round, replace the end cover.
• Replace the mainshaft if the bushing for the 1 st feed pipe is loose or damaged. If the 1 st feed pipe is dam-
aged or out of round, replace it.

A worn or damaged sprag clutch is mostly a result of shifting the transmission in
[Q}l,
~,
or
[Q)
position
while the wheels rotate in reverse, such as rock ing the vehicle in snow.
P Inspect the frame for collision damage.
Q
Inspect for damage and wear:
1, Reverse
se lector gear teeth chamfers .
2. Engagem ent teeth cha mfers of countershaft 4th and reverse gear.
3. Shift fork for scuff marks in center.
4,
Differential pinion shaft fo r wear under pinion gears.
5,
Bottom of 3rd clutch for swirl marks.
Replace items 1,2,3, and 4 if worn or damaged. Iftransmission makes a clicking, grinding. or whirring noise,
also replace mainshaft 4th gear, reverse idl er gear, and countershaft 4th gear in addition to 1, 2,3, or 4.
If differential pinion shaft is worn, overhaul differential assembly, replace ATF strainer. and thoroughly clean
transmission. flush torque converter, cooler. and lines.
If b ottom of 3rd clutch is swirled and transmission makes gear noise, replace the countershaft and final driven
gear.
R Be very careful not to damage the torque converter housing when replaCing the main ball bearing. You
may also damage the ATF pump when you torque down the main valve body. This
will
result in ATF pump
seizure if not detected. Use the proper tools.
5 Install the main seal flush with the torque converter housing. If you push it into the torque converter
housing until it bottoms out, it will block the fluid return passage and result in damage.
