Fluid Pan: Service and Repair
Fluid Level Check
Low fluid level can cause a variety of conditions because it allows the pump to take in air along with the fluid. As in any hydraulic system, air bubbles
make the fluid spongy, therefore, pressures will be low and build up slowly.
Improper filling can also raise the fluid level too high. When the transmission has too much fluid, the geartrain churns up foam and cause the same
conditions which occur with a low fluid level.
In either case, air bubbles can cause overheating and/or fluid oxidation, and varnishing. This can interfere with normal valve, clutch, and accumulator
operation. Foaming can also result in fluid escaping from the transmission vent where it may be mistaken for a leak.
Along with fluid level, it is important to check the condition of the fluid. When the fluid smells burned, and is contaminated with metal or friction
material particles, a complete transmission recondition is needed. Be sure to examine the fluid on the dipstick closely. If there is any doubt about its
condition, drain out a sample for a double check.
After the fluid has been checked, seat the dipstick fully to seal out water and dirt.
The transmission fluid level should be inspected at least every six months.
FLUID LEVEL CHECK PROCEDURE
The transmission has a dipstick to check oil level. It is located on the right side of the engine. Be sure to wipe all dirt from dipstick handle before
removing.
The torque converter fills in both the P Park and N Neutral positions. Place the selector lever in P Park to be sure that the fluid level check is accurate.
The engine should be running at idle speed for at least one minute, with the vehicle on level ground. At normal operating temperature (approximately
82 °C or 180 °F), the fluid level is correct if it is in the HOT region (cross-hatched area) on the oil level indicator. The fluid level will be
approximately at the upper COLD hole of the dipstick at 70 °F fluid temperature.
NOTE: Engine and Transmission should be at normal operating temperature before performing this procedure.
1. Start engine and apply parking brake.
2. Shift the transmission into Drive for approximately 2 seconds.
3. Shift the transmission into Reverse for approximately 2 seconds.
4. Shift the transmission into Park.
5. Hook up DRBIII scan tool and select transmission.
6. Select sensors.
7. Read the transmission temperature value.
8. Compare the fluid temperature value with the chart.
9. Adjust transmission fluid level shown on the dipstick according to the chart.
NOTE: After adding any fluid to the transmission, wait a minimum of 2 minutes for the oil to fully drain from the fill tube into the transmission
before rechecking the fluid level.
10. Check transmission for leaks.
