Hello & Welcome to JA,
Hello, I have a 2007 Cadillac cts. The transmission needs to be filled. How do I fill it?
It is a bit of a proceedure & has to be done with the vehicle level on a lift.I am switching to Q/A to send you the info.
Important: Transmission fluid level can only be accurately checked when the fluid temperature is between 30-50°C (86-122°F).
Important: The transmission fluid may darken with normal use and does not always indicate contamination or oxidation.
Is the fluid color red or light brown with no burnt odor?
Go to Step 4
Go to Step 2
Does the fluid have a burnt odor or a dark brown color?
Go to Step 8
Go to Step 3
Does the fluid have a cloudy or milky appearance?
Go to Step 7
Let the fluid temperature rise until it has reached the specified value. Inspect the fluid level. The level should be even with the bottom of the threaded plug hole.
Is the fluid level low?
Go to Step 5
Go to Step 11
Add DEXRON®VI automatic transmission fluid in increments of 0.5 L (0.5 qt) until the fluid drains from the hole plug.
Did you add more than 1.5 L (1.6 qt) to the transmission?
Go to Step 6
The transmission may have a leak.
Was a transmission leak found?
Go to Step 9
The transmission fluid is contaminated with engine coolant.
Repair or replace the transmission cooler in the radiator.
Is the transmission cooler repair complete?
Important: A very small amount of material in the bottom of the pan is a normal condition.
Was excessive debris found?
Go to Step 10
Important: If the transmission is overhauled, it may be necessary to flush the transmission fluid cooler and pipes.
Add enough DEXRON®VI automatic transmission fluid to bring the fluid to the fluid level to the bottom of the threaded plug hole.
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.
Important: If the level hole plug (36) and O-ring (37) are not damaged, they should be reused.
Is the repair complete?
