TRANSMISSION MAINTENANCE
The transmission is a three-speed-forward, three-speed-reverse, two range Dana 32000 series
powershift transmission. The transmission is bolted directly to the flywheel housing of the en-
gine 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 4 to 5 gallons (15 L to 19 L).
