Note: different driving ratio will be used on the gearbox when the car is traveling in 
different traffic conditions. Therefore, the selected gearbox assembly components 
shall be correct during maintenance, improper part number will affect the driving 
ratio of the gearbox.  
Caution: the gear and shaft of one gearbox are not interchangeable with those of 
another gearbox; otherwise, the gearbox will not function properly.  
The differential assembly is supported by a needle roller bearing.  
 
 
 
 
III. Gearbox Transmission Ratio 
The following is a list of various driving ratios of A15 gearbox. The status of the input 
shaft brake of reverse gear is also illustrated in the list, which makes it easy to engage the 
reverse gear and can reduce gear abrasion.  
 
 
 
 
 
Driving ratio:  
First gear: 3.50 
Second gear: 1.95 
Third gear: 1.36 
Fourth gear: 0.97 
Fifth gear: 0.81 
Reverse gear: 3.42 
Final ratio: 4.12 
Reverse brake: Yes 

Clutch control system: hydraulic control 
 
 
 
 
 
 
IV. Gear Lever 
The arrangement of gears is laid out in a double H shape. (Figure 4)

V. Filling Lubricant 
Note: all Manual A15 gearboxes are required to use ATF+4 Automatic Gearbox Oil. No 
gear oil and engine oil is allowed. Application of incorrect gearbox oil will result in 
difficulty in gear shifting and troubles in bearing, gear and synchronizer.  
Except the aforesaid gearbox oil, no other oils are recommended to be filled into the 
gearbox as they will possibly affect the performance of oil seals.  
Please refer to Gearbox Maintenance for the filling of gearbox oil.  
 
 
 
 
 
 
 

 
Chapter Three: Troubleshooting 
 
Most gearbox troubles are difficulty in gear shifting and impact and noise during gear 
shifting, which are caused by insufficient lubrication, improper lubricant, damaged 
internal component and improper operation.  
I. Difficulty in gear shifting 
The trouble is possibly caused by clutch fault, improper adjustment or deformation of the 
gear-shifting transmission mechanism or its interference with other parts, failure of the 
synchronizer’s synchronizing ring, improper assembly of synchronizer components, 
incorrect installation of synchronizer coupling or abrasion or damage of the gear ring or 
spring gear tooth.  
Worn, damaged, improperly assembled parts or leakage in hydraulic system may also 
cause difficulty in gear shifting. 
II. Gear detachment 
The trouble is possibly caused by improper adjustment of the gear shifting mechanism, 
deformation of the gear-shifting transmission mechanism, failure of the gear-shifting 
locking mechanism, abrasion of the synchronizer coupling or gear tooth surface.  
III. Gear confusion 
The trouble is possibly caused by loosened gear-shifting transmission mechanism, 
loosened or worn-out gearbox gear-shifting mechanism or failure of gearbox interlocking 
device.  
IV. Noise in operation 
Gearbox noise is usually caused by component damage or abrasion.  
The noise may also be caused by worn-out gear or synchronizer tooth, incorrect axial 
clearance of the gear or broken bearing. Worn-out and damaged internal components are 
most usually caused by insufficient lubrication.  
V. Abnormal noise at reverse gear 
It is possibly caused by clutch fault or reverse gear damage.  
VI. Skidding gear 
Skidding of gearbox gears is possibly caused by gear-shifting component damage, 
abrasion of drive gear and synchronizer tooth or incorrect assembly.  
VII. Insufficient lubricant 
Insufficient lubricant is usually due to leakage or incorrect checking method. In the case 
of leakage, there will be apparent oil pooling around the leakage. Compressed air may be 
blown into the gearbox body to force the oil out of the leakage.  
VIII. Overheated gearbox 
It is possibly caused by insufficient gearbox oil quantity or viscosity, insufficient gear 
engagement clearance or insufficient bearing clearance.  
IX. Clutch trouble 
Clutch hydraulic system leakage or air inflow may cause incomplete disengagement of 
clutch.  
Clutch component abrasion, damage or burn may cause trouble in gear shifting or impact 
and noise during gear shifting; abrasion or damage of clutch disc, pressure plate or 
damping spring may also cause trouble in gear shifting or impact during gear shifting.
