welcome to just answer,
You vehicle has somewhat of a complicated prodedure to check the transmission fluid.
Transmission Fluid Check
The oil level control plug (65) is located on the torque converter side of the transmission.
Caution: The engine must be running when the transmission fluid fill plug is removed, or excessive fluid loss will occur. Transmission fluid may be hot. Since the actual fluid level is unknown, stand clear when removing the fill plug. Have a container ready to capture any lost fluid. Do not turn the engine off with the fill plug removed, as you can be injured by hot transmission fluid being expelled out of the oil fill opening.
Check the fluid level. The fluid level should be even with the bottom of the threaded plug hole.
Add DEXRON® III automatic transmission fluid in increments of 0.5 L until the fluid drains from the plug hole.
