GREAT WEBSITE!!! Just bought a 2005 Cooper S for cheap with a jerky upshift and trying to get it fixed. I've flushed the fluid by doing 3 drain and refills which did help but some of the jerky upshift from 2-3 and 3-4 is there. The fluid was dark that came out but was not burnt ir sludgy. Looks like somebody has done a drain and refill before but I have no details of service history.

I'm thinking valve body replacement is next (from Revmax) and l'm looking for some instructions to make sure I get it done correctly. Any help would be appreciated.

Thank you

You have to slightly raise transmission to get to the corner pan bolt but it is possible. Very messy job but take your time and good luck. Also recommend getting a few extra long bolts to help reinstall it and guide it up. M8 bolts if I recall.

 

Thanks EURO for the instructions, really appreciate it. What is the best way to access the bolt(s) that are blocked.
