Description Reviews Note: Sold with 3 bottles of fluid. MINI Cooper Automatic Transmission fliter Flush Kit for all Gen 1 cars. This MINI Automatic Transmission Fluid is just what you need to do a flush in your Gen 1 Cooper S, Automatic Transmission and comes with a new filter and gasket. This is the correct spec fluid, direct from MINI. Normally the transmission hold 6 qts. (dry), but when you're doing a flush, you can only get about 2 ½ qts. in, due to the fluid in the tq converter. To do a more complete flush, you will need to drive the car for a "day," and do it again with the fluid you can find here. 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 it is lacking some information on this 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 jobs. Kit includes: 3 Bottles of Transmission Fluid (83-22-2-220-438) 1 Pan Gasket (24-11-7-566-356) 1 Fluid Filter (24-34-7-551-087 Our friends over at Motoring Alliance have a great how-to article that will help you a lot. Take a read over here. We also added a great photo of where & how to fill the transmission from the top. Note: Sold with 3 bottles (even though the photo shows 5), filter, and new gasket, you may need additional fluid, as stated above.
