Checking Fluid Level with the Keypad
The following procedure will allow you to check your transmission fluid level from inside the vehicle, and it is also more accurate than checking via the dipstick.
To enter the transmission oil level display mode, press the UP and DOWN arrow buttons simultaneously on the mode selector. A two-minute countdown begins when the following conditions are met:
- Engine is at idle
- Transmission sump oil is at operating temperature
- Transmission output shaft has stopped
- Transmission is in neutral
- Oil level sensor is functioning properly
The display should show *8 and then count down to 0. Note that it will take two minutes to complete this countdown. During the countdown, the display flashes and a count (8,7,6,5,4,3,2,1) occurs reducing by one digit every 15 seconds.
NOTE: Failure to meet any of the above conditions will stop the two minute countdown. The shift selector will then display one of the following Oil Level Codes to show the reason for the countdown interruption. The countdown will resume where it stopped once all conditions have been met. Shift selectors with single digit display will display the codes one digit at a time. Shift selectors with two digit displays will display the codes two digits at a time.
| OIL LEVEL CODE | CODE DESCRIPTION |
| oL 0X | Setting time too short |
| oL 50 | Engine RPM too low |
| oL 59 | Engine RPM too high |
| oL 65 | Neutral not selected |
| oL 70 | Sump fluid temperature too low |
| oL 79 | Sump fluid temperature too high |
| oL 89 | Output shaft rotation detected |
| oL 95 | Oil level sensor failed |
After the two minute countdown, the shift selector displays the oil level data as in the following examples:
| OIL LEVEL READINGS | MEANING OF READINGS |
| o, L, o, K | Fluid level is correct |
| o, L, L, o, 1 or OL, LO, 01 | Fluid level is 1 quart low |
| o, L, H, 1 or OL, HI, 01 | Fluid level is 1 quart high |
To exit the oil level display mode, press the NEUTRAL button or simultaneously press the UP and DOWN arrows twice.
