Using Aisin ATF oil

[gmonag]

Here we go again - this old-wives-tale about flushing the gearbox doing harm.

Flushing an engine with old oil can cause problems, but not a auto gearbox. The fluid in the gearbox is constantly circulated through all the galleries, the torque converter and the cooler. There is a filter in the sump (not servicable) which will catch debris. There will only be debris if something is broken internally.

The flush method (so called Gibbons method after a member who posted it here a few years ago) is the official method as described in VIDA. It is simple and quick to carry out and will change almost all the fluid on one go. Do it and your gearbox will improve!

The only equipment you need (apart from normal spanners etc) is a length of clear pvc hose, 5cm of garden hose and a funnel.

I can go into more detail if you wish
