IMPORTANT NOTE: SEE NOTE BELOW

Notes:

This assembly has a bi-metal strip inside that retains fluid until the transmission is warm. Once warm the bypass valve opens and releases the transmission fluid to the oil cooler. This is most often the cause of the "mystery whining/tapping noise" coming from under the passenger seat. The noise is caused from the bi-metal strip not closing properly and the fluid draining backwards.
