- Start the engine and operate the vehicle for 15 minutes or until the transmission fluid reaches an operating temperature of 82-93°C (180-200°F).
- Park the vehicle on a level surface. Apply the parking brake and block the wheels.
- While the engine is idling and with your foot on the brake pedal, move the shift lever through each gear range, ending in Park.
- Check the fluid level, color and condition (transmission fluid conditions are diagnosed by color). The fluid will be higher on the fluid level indicator when the transmission is cold. Conversely, the fluid level will drop when it is checked at operating temperature.
- If it is necessary to add fluid, DEXRON®-III Automatic Transmission Fluid is preferred. DEXRON®-IIE is an acceptable substitute.
Step | Action | Value(s) | Yes | No |

Important: Transmission fluid may turn dark with normal use. This does not always indicate oxidation or contamination. The fluid color should be light brown. Is the fluid color light brown? | -- | -- | |
14 | Drain the fluid to determine if the fluid is contaminated. A very small amount of material in the bottom pan is a normal condition, but large pieces of metal or other material in the bottom pan require a transmission overhaul. Was the fluid contaminated? | -- | ||
15 | Overhaul the transmission. Refer to Unit Repair. Is the overhaul complete? | -- | -- | |

17 | Add new fluid. Is the procedure complete? | -- | -- | |
18 | Change the fluid and the filter. Is this procedure complete? | -- | -- | |
19 | Is the fluid level satisfactory? If not, correct as necessary. | -- | -- | |
20 | Perform the Functional Test Procedure. Is the Functional Test completed? | -- | System OK | -- |
