MANUAL TRANSAXLE DIAGNOSIS

INTRODUCTION

M1221006900615

The manual transaxle can exhibit any of the following 
symptoms: noise or vibration is generated, oil leaks, 
shifting gears is hard or troublesome, or the 
transaxle jumps out of gear.

The causes of these symptoms could come from: 
incorrect mounting, the oil level may be low, or a 
component of the transaxle may be faulty.

TROUBLESHOOTING STRATEGY

M1221007000529

Use these steps to plan your diagnostic strategy. If 
you follow them carefully, you will be sure that you 
have exhausted most of the possible ways to find a 
manual transaxle fault.
1. Gather information from the customer.

2. Verify that the condition described by the 

customer exists.

3. Find the malfunction by following the Symptom 

Chart.

4. Verify malfunction is eliminated.

SYMPTOM PROCEDURES

INSPECTION PROCEDURE 1: Noise, Vibration

DIAGNOSIS

STEP 1. Check the idle speed.
Q: Does the idle speed meet the standard values?

YES : Go to Step 2.
NO :  Refer to GROUP 11A, On-vehicle Service 

− Curb Idle 

Speed Check <2.4L ENGINE> 

P.11A-9

  or GROUP 

11C, On-vehicle Service 

− Curb Idle Speed Check 

<3.0L ENGINE> 

P.11C-9

 .

STEP 2. Check whether the transaxle and engine mount is 
loose or damaged.
Q: Are the transaxle and engine mount loose or damaged?

YES : Tighten or replace the part. Then go to Step 7.
NO :  Go to Step 3.

STEP 3. Check that the oil level is up to the lower edge of 
the filler plug hole.
Q: Is the oil level up to the lower edge of the filler plug 

hole?
YES : Go to Step 4.
NO :  Refill gear oil API classification GL-4 SAE 75W 

− 85W 

or 75W 

− 90. Then go to Step 7.

STEP 4. Check for the specified oil.
Q: Is the specified oil gear oil API classification GL-4 SAE 

75W 

− 85W or 75W − 90?

YES : Go to Step 5.
NO :  If in doubt, replace the oil. Refer to 

P.22A-10

. Then go 

to Step 7.

STEP 5. Remove the transaxle. Check the end play of the 
input and output shafts.
Q: Does the end play of the input and output shafts meet 

the standard value?
YES : Go to Step 6.
NO :  Adjust the end play of the input and output shafts. 

Then go to Step 7.

STEP 6. Disassemble the transaxle. Check the gears for 
wear and damage.
Q: Are the gears worn or damaged?

YES : Replace the gears. Then go to Step 7.
NO :  Go to Step 7.

STEP 7. Check trouble symptoms.
Q: Is the noise or vibration still there?

YES : Return to Step 1.
NO :  This diagnosis is complete. 

INSPECTION PROCEDURE 2: Oil Leaks

DIAGNOSIS

STEP 1. Visual check.
Raise the vehicle, and check for oil leaks. If oil leak is 
difficult to locate, steam clean the transaxle and drive 
the vehicle for at 10 minutes. Then check the leak 
again.

Q: Is the oil leak(s) found?

YES : 

Go to Step 2.

NO : 

Check for the oil leak(s) around the engine. 
Then go to Step 4.
