I have the AISIN 6-speed automatic on my 2015 Cooper S and would like to perform a simple drain/refill of the automatic transmission fluid. Watching the (very few) videos out there on YouTube and seeing how difficult it is to access the topside fill hole (and not really wanting to use the side fill method either), I'd like to purchase an adapter and fill via the drain plug hole underneath the car. Just wondering if anyone knows the correct part I need to order.

On earlier Gen 2 models, it seems like some recommend the Assenmacher Drive Line Filler Adapter, ASM-ATF105. The thread is M10 x 1.0. Will this work for the Gen 3 AISIN 6-speed as well?

One other potential option: The Assenmacher ASM-ATF105 seems to be a copy of the Volkswagen VAS6262-2 tool (VW uses the AISIN 6-speed as well). Should I just order a cheap VAS6262-2 off eBay and call it a day?

Thanks for your help!

 

Update: I ordered the VAS6262-2 tool. It may have worked for the Gen 2 AISIN 6 speed, but it's much too large for the Gen 3 AISIN 6 speed drain plug hole, so no bottom fill for me! After a total of 3 liters ATF drained from the bottom, then I removed the airbox to access the T55 fill hole. I stuck a funnel in there, refilled 3 liters of new Febi ATF, re-assembled and it works great! My take-away: don't be afraid of the top-fill!

 

When I took my F56 2015 into the dealer for a transmission service. The service manager informed me that you don't service the Aisin auto trannys. He said it is indestructible. I asked if he was kidding. He said no. Well, having a Ram 3500 Cummings with an Aisin, I questioned his credibility. Any ideas?

 

Yeah, he is full of crap. Mini likes to tout that its a "sealed" transmission with lifetime fluid, except it does have drain and fill holes and should be serviced at some point. I'd personally do a drain/fill every 30-40k miles as you only drain part of the fluid each time.
