How to Add Manual Transmission Fluid
Here is how to add fluid. Refer to the Maintenance
Schedule to determine what kind of fluid to
use. See Recommended Fluids and Lubricants on
page 629.
1. Remove the filler plug.
2. Add fluid at the filler plug hole. Add only
enough fluid to bring the fluid level up to
the bottom of the filler plug hole.
3. Install the filler plug. Be sure the plug is fully
seated.
Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting. The clutch master cylinder reservoir
is filled with hydraulic clutch fluid.
It is not necessary to regularly check clutch fluid
unless you suspect there is a leak in the system.
Adding fluid will not correct a leak.
A fluid loss in this system could indicate a
problem. Have the system inspected and repaired.
When to Check and What to Use
The clutch master
cylinder reservoir is
located in the rear of the
engine compartment on
the driver’s side of the
vehicle. See Engine
Compartment Overview
on page 480 for more
information on location.
Refer to the Maintenance Schedule to determine
how often you should check the fluid level in
your clutch master cylinder reservoir and for the
proper fluid. See Owner Checks and Services
on page 625 and Recommended Fluids and
Lubricants on page 629.
