R50/53 Automatic transmission fluid change
Automatic transmission fluid change
I have r52 mini cooper s convertible with 39k miles.
i've purchased it as used car from private seller and the previous owner only used for commute around 3 miles a day. anyway, i feel like there is hesitation while accelerating on 1st 2nd 3rd gear. rpm goes up to 4000-5000 and doesn't shift smoothly.
so i'm planning to purchase transmission filter and fluid from amazon and ebay.
Please check the link below and advise.

I just did this. It was a bigger PITA than I thought. Doable but a PITA. I won't do one again even though I know I could do it in two hours or so now. I would reset the ECU then drive it around a while before doing the fluid change to see if it relearned your driving style. There is a sequence of starts and stops you should do to reprogram the transmission. I did this after the fluid change because I had the same issues I did before the change and this final step cleared it up to perfect.

The MCS automatic doesn't require a driving adaptation reset, you can just reset the transmission adaptations and it'll learn to your driving.
There is a fluid transfer pump that makes this job quite a lot easier, or you can slowly pour fluid into the fill hole with a funnel (it sucks). But you also need to have a computer that can read transmission temperature, because there is a set parameter that the fluid level must be checked at to be accurate.
The car also needs to be on level plane when you check the fluid level, which requires it to either be on jack stands of equal height or on a lift, as well as the car running.

Good to know. I was just following other manufacturers procedures in order to hopefully speed up the process.

Absolutely the PITA. I started out filling from the top then went to my friends shop and stole his filler. It got much easier after that. I also stole his scanner to read temperature instead of using my infrared temp gun. Again, it made it much easier.
