Hi.
We have bought an ex-Japan 1998 Mini Kensington automatic. It drives fine but has an intermittent fault. When changing up from 2nd to 3rd it sometimes revs without going into gear. It doesn't always happen and only occurs on that one change up. It goes into gear after about 1 or 2 secs when it does happen and temporarily lifting your foot off seems to help.
Any ideas on what it is / how to fix it?
Cheers,
Bill

Sounds like something called flare which is quite common.

Change the oil if its not new and make sure its 10w40 mineral oil.

When mine was auto it would do it. Especially when cold.

As you say Ease off the accelerator just as it shifts
Up and let the next gear engage before accelerating again. Just limit the slip and snatch when it engages as i can't imagine this does it much good.

I just lived with it. New oil made things a lot better.

I think the actual causes are a combination of factors but as these things work by magic I never really tried to work out why.

An oil and filter change is a good place to start.

 

There's a few threads about oil over on the auto mini forum:

Seems a few people think that oils designed for motorcycles with wet clutches are also suitable for the mini AP auto gearbox. These have the specification JASO MA2.
