The Wacker Neuson Transmission Oil Temperature Sender is a genuine OEM component designed for the BL744 and BL742 series Backhoe Loaders, including the BL744ch, BL744h, BL742h, BL744c, and BL744 EX models. As a direct Wacker Neuson OEM part, the is manufactured to the same specification as the original, ensuring accurate signal output and a drop-in installation into the transmission housing. Sourcing the correct sender matters — a faulty or incompatible unit can produce inaccurate temperature readings and leave the transmission vulnerable to undetected overheating.
Key Features
- Calibrated Signal Accuracy — Engineered to deliver the precise electrical output your machine's monitoring system expects, so temperature readings at the dash reflect actual transmission conditions.
- Genuine OEM Construction — Manufactured by Wacker Neuson to original specification, with correct thread pitch and connector interface for a straight swap into the existing sender port.
- Broad BL-Series Fitment — Confirmed for BL744ch, BL744h, BL742h, BL744c, BL744 EX, and BL742 EX Backhoe Loaders, covering the full BL744 and BL742 model families.
- Protects Transmission Health — A functioning sender keeps the operator informed of thermal load in real time, enabling action before heat-related transmission damage occurs.
- Electrical Safety Compliance — As a verified OEM electrical sensor, the 5100032709 meets the correct resistance and output tolerances required by the machine's electrical system, avoiding false alerts or suppressed warnings caused by mismatched aftermarket units.
The Transmission Oil Temperature Sender monitors the heat level of the fluid inside the transmission and relays that data as an electrical signal to the machine's instrument panel or control system. This allows the operator to track transmission temperature in real time and respond if it climbs into a damaging range. When this sender fails — whether through corrosion, wiring degradation, or physical damage — the temperature gauge may read incorrectly or not at all, leaving the transmission exposed to overheating that can cause costly internal wear or sudden failure.
