Manual Transmission Fluid
When to Check Manual
Transmission Fluid
It is not necessary to check the manual transmission
fluid level. A transmission fluid leak is the only reason
for fluid loss. If a leak occurs, take the vehicle to
your Cadillac dealership service department and have it
repaired as soon as possible.
How to Check Manual
Transmission Fluid
Because this operation can be difficult, you may choose
to have this done at your Cadillac dealership service
department.
If you do it yourself, be sure to follow all the instructions
here, or you could get a false reading.
Notice: Too much or too little fluid can damage
your transmission. Too much can mean that some
of the fluid could come out and fall on hot engine
part or exhaust system parts, starting a fire.
Too little fluid could cause the transmission to
overheat. Be sure to get an accurate reading if you
check your transmission fluid.
Check the fluid level only when your engine is off, the
vehicle is parked on a level place and the transmission
is cool enough for you to rest your fingers on the
transmission case.
To check the fluid level, do the following:
1. Remove the filler plug.
2. Check that the lubricant level is up to the bottom of
the filler plug hole.
3. If the fluid level is good and your vehicle is a CTS,
replace the gasket and reinstall the filler plug. If the
fluid level is good and your vehicle is a CTS-V,
apply LOCTITE
®
#516 or equivalent sealant to the
threads and then reinstall the filler plug.
With either vehicle, be sure the plug is fully seated.
If the fluid level is low, add more fluid as described
in the next steps.
