Claims

[Scope of utility model registration request]

An engine cooling water channel, a branch section provided in the engine cooling channel with a flow rate switching valve, an automatic transmission cooling channel that sends cooling water from this branch section to the oil cooler of the automatic transmission, and a channel that detects the temperature of the engine. The automatic transmission includes a first sensor, a second sensor that detects the temperature of the automatic transmission, and a control circuit that operates the flow rate switching based on the signals from the first and second sensors. An automatic transmission with a retarder, characterized in that the flow rate of cooling water flowing to each is controlled according to the temperature of
