Transmission Cooling





Transmission fluid cooler
The transmission fluid cooler is of an aluminum construction consisting of a tube and louvered fin core-type, the tubes are arranged horizontally for the cross flow of the oil.

A thermostatic control valve is incorporated in the transmission fluid cooler, this maintains the transmission fluid at the optimum temperature for use in the transmission.

When carrying out automatic transmission procedures any drained fluid should be checked thoroughly for any metal filings or particles. If metal filings or particles are evident the automatic transmission fault should be located followed by a thorough flushing of the fluid cooler and fluid cooler lines.
