Q

World Transmission Operation

When a range selection is made the digital display shows the chosen operation (if the ECU determines the shift is acceptable) and the transmission will shift to the initial range as indicated on the display. While in the D (Drive) mode it is not necessary to select the right moment to upshift or downshift during changing road and traffic conditions, the transmission will do it all for you.

Q

World Transmission Operation

Conditions which illuminate the CHECK TRANS light will disable the shift selector and the digital display will show the range actually attained. The transmission will not shift into range if a CHECK TRANS code is active. When the display shows either R or D has been requested and the display is flashing, the requested range has not been achieved due to an inhibit function. Some inhibit functions are vehicle-related and will not result in diagnostic codes.

Q

World Transmission Operation

Because the transmission fluid cools, lubricates, and transmits hydraulic power, it is important that the proper fluid level be maintained at all times.

If the fluid level is too low, the converter and clutches do not receive an adequate supply of fluid. If fluid level is too high, the fluid can aerate. Aerated fluid can cause the transmission to shift erratically or overheat.

Q

World Transmission Operation

Correct Fluid Level: transmission

“OL” is displayed (OL represents Fluid (Oil) Level Check Mode), followed by “OK”. The “OK” display indicates the fluid is within the “OK” zone.

The sensor display and the transmission dipstick may not agree exactly because
the oil level sensor compensates for fluid temperature.

A

29
Q

World Transmission Operation

“OL” is displayed (OL represents Fluid (Oil) Level Check Mode), followed by “LO” (LO represents Low Oil Level) and the number of quarts the transmission fluid is low. Example: “02” indicates 2 additional quarts of fluid will bring the fluid level within the middle of the “OK” zone.

30
Q

World Transmission Operation

“OL” is displayed (OL represents Fluid (Oil) Level Check
Mode), followed by “HI” (HI represents High Oil Level) and the number of quarts the transmission is overfilled. Example: “01” indicates 1 quart of fluid above the full transmission level.

2006-2009 Low or High numbers will be indicated by a “1” not a “01”

38
Q

World Transmission Operation

2006/09 - A Cold Check may be made when the fluid temperature is ___ F – ___ F. Before the engine is started, pull the transmission dipstick and confirm that the transmission fluid level is near the HOT RUN mark.

To perform a Cold Check, do the following:

  1. Start and run the engine at idle (500 to 800 rpm) in N (Neutral) for about one minute.
  2. Park the vehicle on a level surface, apply the parking brake, chock the wheels and
    shift to N (Neutral).
  3. With the engine idling (500 to 800 rpm), shift to D (Drive) and then to R (Reverse) to
    clear air from the hydraulic circuits.
  4. Shift to N (Neutral) and leave engine at idle.
  5. The transmission oil dipstick is located in the access panel at the rear of the engine
    doghouse. Clean the area around the dipstick to insure that no dirt or debris enters the
    transmission.
  6. Remove the dipstick and wipe clean. Reinsert dipstick into the transmission.
  7. Remove the dipstick and check the fluid level. If the fluid level on the dipstick is
    within the COLD RUN band, the level is satisfactory. If the fluid level is not within this band, add or drain fluid as necessary to bring the level within the COLD RUN band.
  8. Perform a Hot Check at the first opportunity after normal operating temperature
    (160oF – 200oF) is reached.
A

60 - 120 degrees

39
Q

World Transmission Operation

The electronic control system is programmed to inform the operator of a problem with the transmission system and automatically take action to protect the operator, vehicle and transmission. When the Electronic Control Unit (ECU) detects a problem condition, the ECU restricts shifting, turns on the CHECK TRANS light and registers a diagnostic code.

A

40
Q

World Transmission Operation

If the CHECK TRANS light does not illuminate during ignition or the light remains on after ignition, the system should be checked immediately.

A

reference

41
Q

World Transmission Operation

Continued illumination of the CHECK TRANS light during vehicle operation (other than
start-up) indicates that the ECU has signaled a diagnostic code. Illumination of the CHECK TRANS light is accompanied by a flashing display from the shift selector. The shift selector display will show the actual range attained and the transmission will not respond to shift selector requests.

A

reference

42
Q

World Transmission Operation

Generally, while the CHECK TRANS light is on, up shifts and downshifts will be restricted and direction changes will not occur. Lever shift selectors do not respond to any operator shift requests while the CHECK TRANS light is illuminated. The lockup clutch is disengaged when transmission shifting is restricted or during any critical
transmission malfunction.
