66939B Transmission Wire Harness (Used) (Superseded by 10266939) l Lull
Item Description: Transmission Control Wiring Harness
Part Number: 66939B
Superseded By: 10266939
Condition: Used
Machine Compatibility: Lull High-Capacity Telehandlers (Select models featuring powershift transmissions)
Category: Electrical System / Transmission Controls
Product Overview
This is a genuine OEM Transmission Wiring Harness, originally produced under part number 66939B and later superseded by 10266939. Removed from a salvaged Lull telehandler, this electrical harness connects the cabin's shift controller (joystick/shifter) directly to the transmission's electronic control valves and gear-selection solenoids.
On heavy-duty material handlers like Lull machines, this harness is responsible for transmitting the critical signals required for forward/neutral/reverse selection and smooth gear stepping. As a used, fully intact OEM replacement, it offers a budget-friendly way to repair electrical faults without paying new factory-harness pricing.
