Does the pressure drop? 

• YES 

  Refer to Checking the cooling system 

• NO 

  Refer to Checking software 

Ensure that the leak is the cause of the coolant coming in contact with the transmission oil by checking the quality of the oil.

If the quality of the transmission fluid had deteriorated due to leakage from the cooling system, replace the transmission, radiator, hoses and expansion tank as below.
