Manual Transmission Fluid

When to Check
A good time to have it checked is when the engine oil is
checked. Refer to the Maintenance Schedule to find
out when to check and change your manual
transmission fluid. See Scheduled Maintenance on
page 6-5.
How to Check and What to Use
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 transmission fluid level, do the following:
1. Remove the filler plug.
2. Check to be sure that the lubricant level is up to the
bottom of the fill opening. On heavy duty
transmissions, an inch of oil level equals about one
gallon of fluid.
3. If the fluid level is good, reinstall the plug and be
sure it is fully seated. If the fluid level is low, add
more fluid as described in the next steps. Refer to
the Maintenance Schedule to determine what kind
of fluid to use. See Part C: Recommended Fluids and
Lubricants on page 6-31.
