JLG

Service Department at

1-877-554-5438 (Domestic) or 1-717-485-5161

(International), if internal transmission repair is required

during the warranty period.

IMPORTANT: To help ensure safety and optimum

performance, replace the transmission if it is damaged.

Refer to the appropriate parts manual for ordering

information.

Cleanliness is of extreme importance. Before attempting

to remove the transmission, thoroughly clean the exterior

of the transmission to help prevent dirt from entering

during the replacement process. Avoid spraying water or

cleaning solution onto or near the transmission shift

solenoids and other electrical components.

1. Park the vehicle on a firm, level surface, fully retract

the boom, raise the boom, place the travel select

lever in the (N) NEUTRAL position, place the neutral

lock lever in the NEUTRAL LOCK position, engage

the parking brake switch and shut the engine OFF.

2. Place an Accident Prevention Tag on both the

ignition key switch and steering wheel, stating that

the vehicle should not be operated. (Refer to Section

1.5, “Accident Prevention Tag Usage.”

)

3. Temporarily block up or support the boom.

4. Unlock and open the rear door. Allow the engine,

transmission and hydraulic fluid to cool.

5. Drain the hydraulic oil reservoir. (Refer to the

appropriate Owners/Operators Manual, “Hydraulic

Oil and Filter Change.”)

6. Disconnect the battery negative (-) cable (Fig. 6-4, 1)

area, including all hoses and fittings, before

proceeding.

WARNING: Risk of severe personal

injury. NEVER lift a transmission alone; enlist

the help of at least one assistant or use a

suitable hoist or overhead crane and sling.

WARNING: DO NOT get under a raised

boom unless the boom is blocked up. ALWAYS

block the boom before

doing any servicing that

requires the boom to be up. Unexpected

lowering of the boom may cause death or

serious injury.

WARNING: Hot hydraulic fluid can

cause severe burns. Wait for hydraulic fluid to

cool before servicing any hydraulic component.
