2.10. A blocked vent can provoke oil leaks. The vent is
located at the top of the transaxle housing. See
Figure 2.10.
2.11. To change the gear lube: Clean the area
around the fill and drain plugs before removing
either.
2.12. Place a drain pan under the transaxle.
2.13. Remove the drain plug at the lower left corner of
the transaxle using a 1/2” wrench. Inspect the
rubber O-ring on the plug, and replace it if it
shows wear.
2.14. Remove the rubber fill plug on top of the tran-
saxle housing. This will allow air to enter the
transaxle faster, which will allow the gear lube to
drain faster.
NOTE: 80-90 weight gear lube is very thick at
low temperatures, and may take considerable
time to drain if the ambient temperature is below
40 degrees farenheit. At low temperatures, oper-
ating (driving) the vehicle immediately prior to
draining the oil will warm the oil, making it easier
to drain.
2.15. Install the drain plug and tighten it to a torque of.
2.16. Add 20 to 24 fluid ounces of gear lube.
3. DIAGNOSIS: CONFIRMING TRANSAXLE
FAULT
3.1. Get as much information as possible from the
customer regarding symptoms and circum-
stances.
3.1. Inspect the vehicle for physical damage and
clues regarding the nature and cause of failure.
3.2. Carefully operate the vehicle if possible, to con-
firm noises and symptoms.
3.3. Eliminate the possibility of problems with the
electronic controls and vacuum actuated shift
mechanism before assuming there is an internal
problem with the transaxle. Isolate the transaxle.
This may be done by operating the transaxle
manually for test purposes. See Figure 3.3.
3.4. Confirm that the problem is not in the brake sys-
tem or the belt drive system.
NOTE: Brake system service and adjustment
procedures can be found in the 2004 Cub Cadet
Technical Service Disc (Form #769-00961).
3.5. If a drive gear (forward or reverse) or the differ-
ential lock fail to engage or disengage by manu-
ally overriding the shift mechanism, the problem
is likely to fall within the transaxle. Performance
problems such as failure to reach full speed are
likely to caused by engine, brake, or belt/clutch
issues.
