AUTOMATIC TRANSMISSION (4L30-E) Checking Transmission Fluid Level and Condition
download
Checking Transmission Fluid Level and Condition Checking fluid level and condition (color and odor) at regular intervals will provide early diagnosis information about the transmission. This information may be used to correct a condition that, if not detected early, could result in major transmission repairs. IMPORTANT: When new, automatic transmission fluid is red in color. As the vehicle is driven, the transmission fluid will begin to look darker in color. The color may eventually appear light brown. A dark brown color with burnt odor may indicate excessive fluid deterioration and signal a need for fluid change. Fluid Level When adding or changing fluid, use only DEXRON ®-lll. Refer to Maintenance and Lubrication in General Information section for maintenance information and servicing interval. CAUTION: DO NOT OVERFILL. Overfilling will cause foaming, loss of fluid, abnor- mal shifting and possible damage to the transmis- sion. 1. Park the vehicle on level ground and apply the parking brake firmly. 2. Check fluid level with engine running at idle. NOTE: Be sure that transmission fluid temperature is below 30°C (86°F). 3. Move the selector lever through all gear ranges. 4. Move the selector lever to “Park”. 5. Let engine idle for 3 minutes and open the overfill screw (1). 6. Add released transmission fluid until it flows out over the overfill screw opening. 7. Let engine idle until a fluid temperature between 32° C (90°F) and 57°C (135°F) is reached, then close the overfill screw (1). Torque: 38 N*m (28 Ib ft) NOTE: Check transmission fluid temperature with scan tool. Minimum fluid level – 57°C (135°F) Maximum fluid level – 32°C (90°F)
