Can you tell me how to removing the transmission oil in a Mitsubishi FTO ??
Answer : Only about 30% of the oil can be drain by removing the pan assembly. You can’t just drain it all out as the majority stays in the torque converter and fluid lines. Transmission fluid is renewed by flushing which requires disconnection of the oil cooler hoses and extension hoses to be fitted.
Fresh oil is sucked from a full container and the old fluid is pumped from the box to an empty container using the connections above.
You need about 5 gallons to do the job properly.
