Product Details

The MAHLE TX 258 55 is a precision-engineered transmission fluid thermostat insert designed to regulate automatic transmission oil temperature for optimal performance and longevity. This OE-quality thermostat ensures your transmission reaches its operating temperature quickly while maintaining consistent temperature control during operation.

Key Features:

  • Opening temperature rating of 122°F (50°C) for precise temperature regulation
  • Standard-flow design for reliable coolant circulation
  • Includes gasket for complete installation
  • Wax expansion element technology for maintenance-free operation
  • OE-equivalent quality from the world's leading thermostat manufacturer
  • Designed to vehicle manufacturer specifications

MAHLE Original thermostats utilize a proven wax expansion element design that automatically opens and closes based on fluid temperature, ensuring your transmission operates within its optimal temperature range. This helps reduce transmission wear, improves shift quality, and can contribute to fuel savings. As transmission fluid thermostats should be replaced whenever the cooling system is serviced or accessed, the TX 258 55 provides a reliable, long-lasting replacement solution.

Had to order twice ordered wrong amount first time.

Thanks

You seem to have the best price and your pictures help a lot. HOWEVER -- no place did my order say "Mercury Grand Marquis 2003 *Passenger Side* Glass -- and that has me concerned because I have to go by make/model/yr and then picture alone!

Paypal payment was a little awkward but it looks like it worked
