Check Plug
To "Check" for the correct fluid level, you must
remove the check plug, which is located in the corner
of the pan, and is removed with a 10 mm allen wrench,
as shown in Figure 41.
We have provided you with a cut-away drawing of
the bottom oil pan and the check plug so that you will
understand how this system works. Notice that the oil
pan actually has a "stand-pipe", as shown in Figure
42, that screws into the check plug hole and extends
up into the bottom pan, which is our way to establish
the proper fluid level in the transaxle. By removing
the "Check" plug from the oil pan, the fluid should just
trickle over the "stand-pipe" and out through the
center of the stand-pipe in the oil pan, as shown in
Figure 43.
The "stand-pipe" can be removed with the 10mm
allen socket to facilitate draining the transaxle fluid
from the bottom pan.
To "Fill" or "Add" fluid to the transaxle you must
use the fill pipe, usually located by the front case
connector, as shown in Figure 35. Some units have a
plug in this location and some units have neither,
usually the remote cooler models.
If your unit does not have a fill pipe, the only
alternative is to use a pump and fill through the check
plug and stand pipe. Only the approved type of ATF
fluid should be used, as shown below.

Note: If the "stand-pipe" is removed, it must be
installed by hand tightening only with the allen
socket and ensure it is completely seated. If not, the
fluid level will not be correct and the bottom of the
check plug may seat against the stand-pipe instead
of seating on check plug sealing washer.
