Manual Transmission Fluid - Chevrolet 2006 Colorado Owner's Manual

Manual Transmission Fluid

When to Check
A good time to have it checked is when the engine oil is
changed. However, the fluid in your manual transmission
does not require changing.
How to Check
Because this operation can be a little difficult, you may
choose to have this done at your GM 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 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.

Then, follow these steps:
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, install the plug and be sure
it is fully seated. If the fluid level is low, add more
fluid as described in the next steps.
