Automatic Transmission External Controls Ford Taurus X I

TORQUE SPECIFICATIONS

TORQUE SPECIFICATIONS

Scheme 1

The transaxle shift control linkage consists of

1. a selector lever cable that connects the transaxle manual lever to the selector lever assembly.
2. a brake shift interlock actuator that is integral to the selector lever assembly.
3. a transmission control switch (TCS) that turns off the operation of 6th gear.

The selector lever assembly

1. locks the transaxle selector lever in the PARK position when the ignition switch is in the LOCK position.
2. requires the transaxle selector lever to be in the PARK position to turn the ignition switch to the LOCK position.

Range Selection

This transaxle has 5 range positions: P, R, N, D and L.

Scheme 2

Park

In the PARK position

1. there is no powerflow through the transaxle.
2. the parking pawl locks the final drive.
3. the engine may be started.
4. the ignition key may be removed.

Reverse

In the REVERSE position

1. the vehicle may be operated in a rearward direction, at a reduced gear ratio.
2. engine braking will occur.

Neutral

In the NEUTRAL position

1. there is no powerflow through the transaxle.
2. the output shaft is not held and is free to turn.
3. the engine may be started.

Drive Position With Overdrive (O/D)

DRIVE is the normal position for most forward driving.

DRIVE provides

1. automatic shifts - 1st through 6th gears.
2. apply and release of the torque converter clutch (TCC).
3. maximum fuel economy during normal operation.

Manual L Position

This position provides

1. maximum engine braking.
2. downshifts to the lowest available gear for the current vehicle speed.

Manual L position allows for 1st gear when the vehicle reaches slower speeds.

Scheme 3

Drive with overdrive (O/D) cancel and grade assist is activated when the transmission control switch (TCS) is pressed. The TCS is located on the selector lever knob. When the TCS is pressed, the 6th gear or O/D upshift is prevented or the transaxle shifts down to 5th gear. The TCS is meant to be used when driving conditions cause excessive shifting from 6th to other gears such as hilly terrain, mountainous areas or when engine braking is required.

O/D Cancel

1. O/D is cancelled.
2. the transaxle operates in gears 1 through 5.
3. the O/D OFF lamp illuminates on the instrument cluster.

Grade Assist

1. Improves vehicle handling in hilly terrain or mountainous areas by providing additional grade (engine) braking and extends lower gear operation on uphill climbs.
2. Additional engine braking is provided through the automatic transaxle shift strategy which reacts to vehicle inputs (vehicle acceleration, accelerator pedal, brake pedal and vehicle speed).
3. The transaxle will select gears that will provide the engine braking desired, based on the vehicle inputs, this will increase engine RPM. during engine braking.

It is recommended to return to DRIVE mode on flat terrain to provide the best fuel economy and transaxle function. The transaxle returns to O/D when the TCS is pressed again or anytime the key is turned OFF.

Inspection and Verification

1. Verify the customer concern by operating the system.
2. Visually inspect for obvious signs of mechanical or electrical damage.
3. If an obvious cause for an observed or reported concern is found, correct the cause before proceeding to the next step.
4. If the concern is not visually evident, verify the symptom. Go to «Symptom Chart - External Controls»(/ford/taurus-x/i-2007-2009/remont/automatic-trans/#automatic-transmission-external-controls) or Go to «Symptom Chart - Noise, Vibration and Harshness (NVH)»(/ford/taurus-x/i-2007-2009/remont/automatic-trans/#automatic-transmission-external-controls) .

Note. Noise, vibration and harshness (NVH) symptoms should be identified using the diagnostic tools that are available. For a list of these tools, an explanation of their uses and a glossary of common terms, refer to NOISE, VIBRATION AND HARSHNESS article. Since it is possible any one of multiple systems may be the cause of a symptom, it may be necessary to use a process of elimination type of diagnostic approach to pinpoint the responsible system. If this is not the causal system for the symptom, refer back to NOISE, VIBRATION AND HARSHNESS article for the next likely system and continue diagnosis

If the selector lever cannot be moved out of the PARK position when the ignition is in the ON position and the brake pedal is depressed

1. Apply the parking brake and remove the ignition key.
2. Remove the access panel.
3. Using an suitable tool, depress the brake shift interlock override mechanism on the selector lever, apply the brake, depress the button on the selector lever and move the selector lever into NEUTRAL.
4. Start the vehicle.
5. To install, reverse the procedure.

Selector Lever Cable Adjustment

1. Disconnect the selector lever cable end from the manual control lever.
2. Place the manual control lever in DRIVE. Rotate the manual control lever clockwise until it stops. Rotate the manual control lever counterclockwise one detent.
3. Place the selector lever in DRIVE.
4. Unlock the adjuster. Pry the latch up. Push the lock tab to slide it over.
