Product Details
Keeping your E53 X5 automatic transmission cool is essential for longevity and peak performance. The factory transmission thermostat circuit relies on plastic housings and o-ring seals that deteriorate over time. When the transmission thermostat fails or it's mounting assembly cracks, coolant loss follows putting your transmission at risk of overheating under load.
This Automatic Transmission Thermostat Refresh Kit packaged by Turner Motorsport overhauls the complete thermostat assembly beneath the expansion tank. Engineered for BMW drivers who demand absolute reliability, this kit restores crisp temperature control to your transmission cooling circuit and replaces vulnerable plastic components before they leave you stranded.
Features
- Complete overhaul kit for the E53 automatic transmission cooling thermostat circuit
- Maintains proper fluid temperatures in the transmission oil cooler under high stress
- Fixes chronic coolant leaks originating from the mounting plate and water pipe connections
- Heavy duty composite construction resists heat degradation and cracking
- Seamless snap-in integration with original radiator and expansion tank connections
