WORK FLOW
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate. In
general, each customer feels differently about a malfunction. It is important to fully understand the symptoms
or conditions for a customer complaint.
Make good use of the two sheets provided, AT- 3 8 , "
Information From Customer" and AT- 3 9 , "Diagnostic
Worksheet" , to perform the best troubleshooting possible.

Inspections Before Trouble DiagnosisBCS00102
A/T FLUID CHECK
Fluid Leakage and Fluid Level Check
Inspect for A/T fluid leakage and check the A/T fluid level. Refer to AT- 1 4 , "Checking A/T Fluid" .
A/T Fluid Condition Check
Inspect the A/T fluid condition.
STALL TEST
Stall Test Procedure
1. Check ATF and engine oil levels. If necessary, add ATF and oil.
2. Drive vehicle for approximately 10 minutes or until ATF and
engine oil reach operating temperature.
3. Set parking brake and block wheels.
4. Install a tachometer where it can be seen by driver during test.

It is good practice to mark the point of specified engine
rpm on indicator.
5. Start engine, apply foot brake, and place selector lever in “D”
position.

Road TestBCS00103
DESCRIPTION

The purpose of the test is to determine overall performance of A/T and analyze causes of malfunctions.

The road test consists of the following three parts:
1. Check before engine is started. Refer to AT- 4 8
.
2. Check at idle. Refer to AT- 4 8
.
3. Cruise test

Inspection all the item from Part 1 to Part 3. Refer to AT- 5 0 , AT- 5 1 and AT- 5 2 .

Before road test, familiarize yourself with all test procedures and items to check.

to be no good after road test. Refer to the following.
Refer to AT- 6 7 , "
CONSULT-II Function (A/T)" , AT- 7 6 , "Diagnostic Procedure Without CONSULT-II" and
