Abnormal shift

Description

• Shifts incorrectly (incorrect shift pattern)

(e.g. : Vehicle shifts from 1st to O/D directly when accelerating with accelerator pedal depressed
slightly)

(TROUBLESHOOTING HINTS)

1. Throttle position (TP) sensor malfunction or not adjusted correctly
2. Shift solenoid valves (A, B, C) worn
3. Control valve stuck
4. Differential assembly malfunction
5. TCM malfunction

Step

Inspection

Action

1

Check that no diagnostic trouble codes exist by
retrieving DTC's with a scan tool

Yes

Go to next step.

No

Diagnostic trouble code(s) displayed on O/D
indicator or scan tool.

• Check for cause of diagnostic trouble

code(s)

If problem remains, go to next step.

2

Are resistance and output voltage of shift
solenoids (A, B, C) at TCM terminals OK?
Vb : Battery voltage

Yes

Go to next step.

No

If resistance is not OK, check for
malfunctioning parts and wiring.

• Shift solenoid A
• Shift solenoid B
• Shift solenoid C

If resistance is OK but voltage is not, replace
TCM.

Solenoid valve resistance : 14~18Ω

• H-01/30 terminal : Shift solenoid A
• H-01/33 terminal : Shift solenoid B
• H-01/32 terminal : Shift solenoid C

3

Are resistance and output voltage of throttle
position (TP) sensor at TCM terminals OK?
Vb : Battery Voltage

H-01/38 terminal : Throttle position (TP)
sensor

Yes

Go to next step.

No

If resistance is not OK, check for
malfunctioning parts and wiring.

• Throttle position sensor

If resistance is OK but voltage is not, replace
TCM.

4

Replace with known operational TCM. IS
problem corrected?

Yes

Replace TCM.

No

Replace control valve body assembly.
If problem remains, overhaul transaxle and
repair or replace parts as ncessary.

16

Frequent shifting

Description Downshift occurs when accelerator depressed slightly in D, 2, and 1 ranges (except O/D OFF mode)

(TROUBLESHOOTING HINTS)

1. Throttle position (TP) sensor malfunction or not adjusted correctly
2. TCM malfunction
3. Control valve stuck

Step

Inspection

Action

1

Check that no diagnostic trouble codes exist by
retrieving DTC's with a scan tool

Yes

Go to next step.

No

Diagnostic trouble code(s) displayed on scan
tool.

• Check for cause of diagnostic trouble

code(s)

If problem remains, go to next step.

2

Are measurements at TCM terminals OK?

H-01/38 terminal : Throttle position (TP)
sensor (from ECM)

Yes

Go to next step.

No

Check for malfunctioning parts and wiring.

• Throttle position (TP) sensor

3

Replace with known operational TCM. Is
problem corrected?

Yes

Replace TCM.

No

Replace control valve body assembly.
If problem remains, overhaul transaxle and
repair or replace parts as necessary.

17

Shift point high or low

Description

• Shift points do not match shift diagram
• Shift delayed when accelerating
• Shift occurs too fast when accelerating and engine speed does not increase

(TROUBLESHOOTING HINTS)

1. Throttle position (TP) sensor malfunction or not adjusted correctly
2. Input/turbine speed sensor malfunction
3. Transaxle fluid temperature sensor malfunction
4. Selector lever installation or adjustment incorrect
5. Shift solenoids valves (A, B, C) worn
6. PCM malfunction
7. Control valve stuck
8. Transaxle range switch malfunction or not adjusted correctly
