FLUID RECOMMENDA TIONS

(5) Chock the wheels and take any other steps necessary keep the vehicle from moving. With the engine running, remove the dipstick from the tube and wipe clean. Insert the dipstick into the tube until it stops. Then remove it. Check fluid level reading. Repeat the check procedure verify the reading.

NOTE: Safe operating level is within the “HOT RUN” band the dipstick Figure 2–1 and Figure 2–2. The width the “HOT RUN” band represents approximately 1.0 liter (1.06 quart) fluid normal operating sump temperature.

the fluid level is not within the “HOT RUN” band, add drain necessary bring the fluid level within the “HOT RUN” band.

Consistency Readings. Always check the fluid level least twice, with the engine running. Consistency (repeatable readings) is important maintaining accuracy the readings. inconsistent readings persist, check the transmission breather sure it is clean and unclogged. readings are still inconsistent, contact your nearest Allison distributor dealer .

2–5. KEEPING FLUID CLEAN

Prevent foreign material from entering the transmission using clean containers, fillers, etc. Lay the dipstick in a clean place while filling the transmission.

CAUTION: Containers fillers that have been used for antifreeze solution engine coolant must NEVER used for transmission fluid. Antifreeze and coolant solutions contain ethylene glycol which, if put into the transmission, can cause the clutch plates fail.

CAUTION: DEXRON ® VI is restricted 1000/2000 transmissions beginning with serial number 6310670488.

Hydraulic fluids (oils) used in the transmission are important influences transmission performance, reliability , and durability . Only fluids meeting TES 295, TES 389, DEXRON ® III, DEXRON ® VI fluid specifications are acceptable for use in 1000 and 2000 Product Families transmissions.
