This Aisin Automatic Transmission Fluid AFT-0T4 is just what you need to do a flush on your Gen 1 or 2 Cooper S, Automatic Transmission. This is the correct spec fluid for your MINI. It's actually the same fluid that's in the MINI bottle, just with a different label!  And because it doesn't say MINI, we can sell it for a lower price! And we all like a price savings. Normally, the transmission hold 6 qts. (dry), but when you're doing a flush, you can only get about 2 ½ -3 qts. in due to the fluid in the torque converter. To do a more complete flush, you need to drive the car for a "day," and do it again. You may even want to do it a third time depending on how the fluid is looking. Each time you drain it, you will see the color of the fluid go from a really dark red/brown to a brighter red color. You can now be the judge. A Bentley manual is helpful anytime you're working on your MINI, but is lacking some information on this particular transmission flush. See the below how-to for better details. This is not a difficult job; but it comes in a harder skill level than most other jobs.
