TRANSMISSION MAINTENANCE
The transmission is a six-speed-forward, three-speed-reverse, Funk Model 2000,
powershift transmission. The transmission is bolted directly to the flywheel housing of the
engine and is connected by drive shafts to the front and rear axles. A torque converter
transmits power from the flywheel to the transmission. The transmission gears are all
constantly in mesh, and there is a series of clutches that control the direction and speed of
the output.
TRANSMISSION OIL:
The oil used in this transmission is Mobil ATF D/M automatic transmission fluid, with the
Allison C-3 rating. See the recommendations below. Other oils can cause shortened
transmission life due to material incompatibility and inadequate frictional properties for
clutch discs. The refill capacity is about four to five gallons (15 L to 19 L).

CAUTION: Do not use any oil with an EP additive.
Check the oil level weekly. The dipstick is located near the front end and right-hand side of
the transmission, below the small fluid reservoir for the parking brake. Make sure the area
around the dipstick is clean before removing. Check the oil level in neutral at idle speed
with the oil warm. Raise the oil temperature to 200
F (90°C) by stalling the transmission.
W A R N I N G
When stalling the transmission, make sure it is in sixth gear, the service and parking
brakes set and the area is clear of personnel and obstacles. Do not exceed 30
seconds or 200
F (90°C) oil temperature, whichever comes first, at full governed
speed. Do not leave the operator seat while stalling the transmission.
Idle the engine and return the shifter to neutral. Check the oil level quickly, before the oil
cools to 100
F (40°C). Maintain the oil level to the full mark on the dipstick at these
conditions.
TRANSMISSION FILTER: (Note--The transmission filter may be found in the Parts Manual
under "Oil Cooler and Filter Installation.")
The transmission is equipped with a cooler behind the radiator and a filter under the battery
box, behind the fuel tank. Change the filter on a new machine after the first 20 hours.
Thereafter, the filter should be changed whenever the indicator light on the dashboard
stays on with the oil above 100
F (40°C) or every 200 hours or 6 months, whichever is
sooner. Use the following procedure:
