Diagnosis and Testing

General Equipment

Inspection and Testing

1. Verify the customer concern.

2. Visually inspect for obvious signs of mechanical or electrical damage.

3. Resolve any obvious causes for a concern found during the visual inspection before carrying out any further tests.

4. If the concern persists, check the symptoms and proceed according to the Ford approved diagnostic tool instructions.

Inspection and Verification - Manual Transaxle

The following checks should be carried out before repairing or installing a new transaxle.

The inspection and verification of manual transmission concerns can be considered in three main areas.

Gear Shifting Concerns



Clutch does not operate correctly.



External gearshift mechanism REFER to:

External Controls

(308-06B Manual Transmission/Transaxle External Controls - Vehicles With: 5-Speed Manual Transaxle - MTX75, Description and

Operation),

External Controls

(308-06C Manual Transmission/Transaxle External Controls - Vehicles With: 6-Speed Manual Transaxle - MMT6, Description and

Operation).

Transmission noise concerns



Check the engine and transmission mountings for sufficient clearance to the transmission and the body.



Other noises except gearshift noises



Go through the driving situations/tests described in the table below under the conditions described there and answer each part of the diagnosis with a "Yes"
or "No".

NOTE: If the response to one or more diagnoses is "Yes", the transmission must be removed and the dual mass flywheel checked according to GO to
Pinpoint Test

Fluid Leakage Concerns



Check that the leaking fluid is actually transmission fluid and not hydraulic fluid (from the hydraulically operated clutch) or engine oil.



Check the transmission fluid level. If necessary, drain off any excess fluid.



Locate the oil leak with the aid of a fluorescent test fluid and an ultraviolet inspection lamp.



Clean the transaxle and the adjacent areas carefully before road testing.

Symptom Chart – General Concerns

Ford approved diagnostic tool

Item

No.

Situation, test / diagnosis

Yes No

Driving situation:

Road test the vehicle. Accelerate the vehicle with maximum torque in 5th or 6th gear. REFER to:

Specifications

(308-01B Clutch - Vehicles With: 5-Speed Manual Transaxle - MTX75, Specifications),

Specifications

(308-01C Clutch - Vehicles With: 6-Speed Manual Transaxle - MMT6, Specifications),

Specifications

(308-01D Clutch - Vehicles With: 6-Speed Manual Transaxle - M66, Specifications).

Diagnosis:
Are there extremely harsh vibrations from the powertrain? Vibrations disappear when the accelerator pedal is released briefly.

Driving situation:

Road test the vehicle. Drive the vehicle in simulated "stop and go" mode (1st gear). Check for transmission rattle during gentle acceleration and
deceleration.
Diagnosis:
Are there noises from the powertrain in driving situations between idling speed and a maximum of 2000 rev/min which occur at a specific, vehicle-
dependent vehicle/engine speed?

Driving situation:

Raise the vehicle. Check all engine/transmission and exhaust mountings with the engine not running, while starting the engine and when it is idling.
Diagnosis:
Does the engine/transmission shake severely or make rattling noises during starting? Longer time before engine reaches idle speed. Renew any
damaged components (engine/transmission or exhaust mountings) and redo the test.

Driving situation:

Check the front axle driveshafts and the manual transmission. Lock the wheels and apply the parking brake. Start the engine, engage 1st gear and
slowly release the clutch pedal while the engine idles.
Diagnosis:
Engine speed does not drop, power not transferred, vehicle does not move.

Driving situation:

Start engine, put shift lever in neutral and slowly release the clutch. Switch off the engine.
Diagnosis:
Hard metallic noise as the engine stops, coming from the manual transmission during the last engine revolution before the engine finally stops, is
NOT caused by the dual mass flywheel. On vehicles with a diesel engine and without an intake manifold flap solenoid valve, the concern (harsh,
metallic noise) cannot be resolved by installing a new dual mass flywheel. In diesel engines with an intake manifold flap solenoid valve, check the
operation of the solenoid valve.
If a clattering noise is detected as the engine is switched off with the clutch pedal depressed, check the transmission housing for grease residues
(more than 2 grams) from the dual mass flywheel (remove the starter motor and check the bell housing).

Symptom

Possible Sources

Action

High-effort gear
shifting in one or more
gears
