Transmission Cooler

A transmission cooler is designed to keep fluids at a nominal temperature during periods of heavy use, or high heat. If yours is leaking, replace it now to prevent fluid loss and catastrophic failure.

The transmission oil cooler allows fluid to pass through the core, dropping the temperature of the fluid before it returns to the transmission. This prolongs fluid life and viscosity, as well as providing a cooler fluid to drop transmission temperatures which can be vital to the life of a transmission.

The oil cooler/heat exchanger for the automatic transmission is one of the most overlooked sections of the E90 335d cooling system. The cooler (heat exchanger) is a part of the overall cooling system and uses coolant circulated from the regular cooling system to cool the transmission oil running through this small cooling block. We recommend servicing or cleaning the heat exchanger along with any cooling system overhaul. Or if you're having transmission faults (especially for temperature) you may want to clean the transmission cooler anyway. Replacing or cleaning the heat exchanger components could lead to better shifting of the automatic as the cooler itself can become clogged. If you're experiencing harder or hesitating shifts, and the internal transmission temperature is rising without being regulated, the components in this system are the likely cause. Staying on top of the cooling needs of the transmission will help prevent a very costly transmission repair in the future.

Over time the elements can get to your oil cooler and cause it to leak, and lose fluid and cooling potential.
