1. Manual Transmission and
Differential
Symptom and possible cause Remedy
1. Gears are difficult to intermesh.
The cause for difficulty in shifting gears can be classified into two kinds: one is malfunction of the gear shift system and the
other is malfunction of the transmission. However, if the operation is heavy and engagement of the gears is difficult, defective
clutch disengagement may also be responsible. Check whether the clutch is correctly functioning, before checking the gear
shift system and transmission.
(a) Worn, damaged or burred chamfer of internal spline of
sleeve and reverse driven gearReplace.
(b) Worn, damaged or burred chamfer of spline of gears Replace.
(c) Worn or scratched bushings Replace.
(d) Incorrect contact between synchronizer ring and gear
cone or wearCorrect or replace.
2. Gear slips out.
(1) Gear slips out when coasting on rough road.
(2) Gear slips out during acceleration.
(a) Defective pitching stopper adjustment Adjust.
(b) Loose engine mounting bolts Tighten or replace.
(c) Worn fork shifter, broken shifter fork rail spring Replace.
(d) Worn or damaged ball bearing Replace.
(e) Excessive clearance between splines of synchronizer hub
and synchronizer sleeveReplace.
(f) Worn tooth step of synchronizer hub (responsible for slip-
out of 3rd gear)Replace.
(g) Worn 1st driven gear, needle bearing and race Replace.
(h) Worn 2nd driven gear, needle bearing and race Replace.
(i) Worn 3rd drive gear and bushing Replace.
(j) Worn 4th drive gear and bushing Replace.
(k) Worn reverse idler gear and bushing Replace.
3. Unusual noise comes from transmission.
If an unusual noise is heard when the vehicle is parked with its engine idling and if the noise ceases when the clutch is
disengaged, it may be considered that the noise comes from the transmission.
(a) Insufficient or improper lubrication Lubricate or replace with specified oil.
(b) Worn or damaged gears and bearings Replace.
NOTE: If the trouble is only wear of the tooth surfaces, merely
a high roaring noise will occur at high speeds, but if any part
is broken, rhythmical knocking sound will be heard even at
low speeds.
