Transmission Oil Pressure Switch for Powershift Hydraulic Systems SKU: QT43091

When transmission oil pressure drops below operating levels, your powershift system loses the hydraulic force needed for smooth gear changes—leaving you with harsh shifts, delayed engagement, or complete transmission failure during critical field work. This pressure switch monitors hydraulic pressure in the gearbox circuit and signals the control system to prevent damaging low-pressure operation.

Why This Switch Matters

• Prevents transmission damage by shutting down operation before hydraulic pressure drops too low
• Sealed housing designed for farm conditions resists oil contamination and moisture intrusion
• Durable contacts handle frequent cycling without failure during daily operation
• Compact design fits tight mounting spaces in modern tractor transmission housings

With 55+ years of helping farmers keep equipment running, S&H Parts understands the importance of reliable hydraulic monitoring. Clean the pressure port and apply proper thread sealant during installation—overtightening can damage the switch body.
