Good To Know
Q: How do I know if this transmission pressure sensor is failing? A: Symptoms include an illuminated transmission warning light, erratic pressure readings on the dash gauge, or a transmission that shifts harshly or slips due to undetected low pressure.
Q: Can I install this sensor myself? A: Yes, the sensor typically threads into the transmission housing and connects with a single electrical plug, but ensure the tractor is powered down and pressure is relieved before removal.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
