Checking Fluid Levels
- Using a scan tool, monitor the Transmission Fluid Temperature (TFT) using PID: TFT. Start the vehicle. Engine idle speed should be approximately 650 RPM.
- Run engine until the recommended TFT is between 81-120°F (27-49°C). The fluid level can be checked above 122°F (50°C) using this procedure.
- Move the gearshift lever slowly, stopping in each gear. Place gearshift lever in the Park position. Raise and support the vehicle. Set vehicle as close to level as possible.
- If needed, the Drive Pinion Angle Gauge (205-025), can be used to assist in leveling the vehicle. See Fig 1 . Place a drain pan under the transmission.
- With the transmission in the Park position and the engine running, use a 3/16" Allen key to remove the fluid level indicator plug. See Fig 2 . Allow the fluid to drain. Wait approximately one minute.
- When the fluid comes out as a thin stream or a drip, it is at the correct level. If no fluid comes out of the hole, fluid will need to be added. Continue with this procedure. Install the Fluid Fill Tool (307-437), into the transmission fluid pan. See Fig 3 .
- Using the Oil Suction Gun (303-D104), extract approximately one pint of clean ATF from a suitable container. Using the oil suction gun and fluid fill tool, fill the transmission with clean ATF. See Fig 4 . Remove the oil suction gun.
- Allow fluid to drain. Wait approximately one minute. When fluid comes out as a thin stream or drip, the fluid is at correct level. If no fluid drains from the plug, continue adding clean ATF in 1/2-pint increments until fluid starts to drain from the plug.
- Remove the fluid fill tool from the pan. Reinstall the fluid level indicator plug and tighten to specification. See TORQUE SPECIFICATIONS . Lower the vehicle. Check the operation of the transmission and inspect for leaks.
NOTE:
It will be necessary to hold the drain plug (larger plug) with a wrench when removing the fluid level indicator plug.
