We've all seen the threads debating what kind of ATF to use. Can we talk about how to change it? As far as I can tell, there are at least two methods:
- Multiple partial drain/refills: the most common DIY method where you drain about a third of the transmission at a time, top it up, start the car and run through the gears, rinse and repeat twice.
- A flush machine: this is a machine with a pump in it which connects to the lines leading from the transmission to the radiator. This machine essentially replaces the radiator in the loop and receives dirty fluid from the transmission and sends back fresh fluid from a pre-loaded resevoir. I'm told that these aren't the safest and can "bend fins inside the torque converter", Is this bro science? For the record, I have a Toyota 86 with a variant of the AISIN A960E.
- ???? I think I have seen people referring to a process that is DIY but also somehow uses the lines between the transmission and the radiator? Not sure
