I would have recommended the same company as well .Not a straight swap I'm afraid, but can be done. it requires all sorts of other bits such as drive shafts etc. I know a few of the MINI tuners have done this conversion. Would recommend one but they are no longer sponsors here, so promoting them is frowned upon.
As has been said if you convert to the 6-speed Cooper S Getrag box several other parts must also be changed to match, such as driveshafts, gearbox mounting, slave cylinder, clutch and flywheel, etc.my 52 plate coopers gearbox has gained a slight whine!
would anyone be able to tell me if its possible to replace the midlands gearbox with the r53 6 speed gearbox any modifications or just a strait swap?
Would be a lot of work and probably some good money too, but hte end product would be fantastic. I want one myself, but i'm not a mechanic Alas I'll probably end up with another 5-speed.thanks all!
as im a mechanic i would probably do it myself but it seems alot off work and lots of ££££
