Hi, I’m Ana & I’m new to this forum.
I have a Mini Cooper 2005 convertible owned since new. Approx 54k miles (currently in garage). The gearbox has failed & ive decided to replace it; love my faithful & until now reliable car. Garage gave me details of either new or secondhand - with estimates. No mention of reconditioned option.
After finding this forum & some Google searching interested in finding out more about this option.
Any thoughts/recommendations by the members would be appreciated. How reliable is the refurb offering; what’s best refurb or taking a punt with secondhand?
Many thanks - all views/help very welcome.

by far best option is a 6 speed conversion ie the 6 speed box off the r53 is common upgrade as this gearbox is very strong,,, just need the gear shift and cables and flywheel and clutch off one,, i have a number of a guy who has a couple of second hand kits ready to go if needed it,, or find a mini breaker and do same thing,,, trouble with the 5 speed gear box is they are weak the post 2005 are better but still not perfect,, the midland early gearboxes are total rubbish i know people who had brand new cars back in 2002 and within 15k needed new gearboxes due to noises whine etc and failure to select a gear,,, if go 5 spreed option you want a gear box from a very late 2005 getrag gearbox when fitted ask them to put fully synthetic gear oil with molly-slip addictive in link below for it its makes the oil more slippery i use it in all my stuff works a treat,
warning any one reading this NEVER ADD THIS STUFF TO A LIMITED SLIP DIFF CLUTCH PACK DIFF WONT END WELL LOL

Hi Mike
Thanks so much. Very useful & helpful. I’ll speak to the garage; they are currently looking for a secondhand (not sure which model).

Unlike earlier Coopers with the
lousy 5-speed Midlands, the
2005 R50 has the 5-speed Getrag
which is pretty reliable in that car
despite your experience. Putting in
another Getrag 5-speed is a good
choice as it goes right in without
needing to source a lot of extra parts,
like you have to do to put the 6-speed in.
The 6-speed Getrag is a better, more
robust transmission, however, if you
already have access to the axles,
flywheel, clutch, starter, clutch line,
shifter cables and box, and other
miscellaneous bits needed to make it fit.

Hi Cristo,
‘Thanks for that advice. My garage has told me today that they have sourced a replacement Getrag. It’s history suggests it got some life left. Their advice/message to me mirrors your comments. So I’m taking a punt on the secondhand 5 speed.
‘Really appreciate the advice provided by both you & Mike - confident I’m giving informed consent. ?

Well? You may not have a bad gear box. Lots of people while waiting for traffic to go by leave their clutch pushed in, instead of setting the car in neutral, that’s if your car is manual instead of automatic. If it’s manual? Have your clutch checked, regardless I just had my clutch resurfaced instead of replaced, regardless it seems that the only way to get to the clutch? The engine has to be removed. I have my vacation home and my 2005 Mini Cooper 1.6L Conv. In Costa Rica and I only paid to my tech $346. ??Not bad, at the dealer it would have costed me here in CR like closer to $1500. I’d suggest you find a good local mechanic and (not the dealer??) that has a bit of experience with minis and gave him check your gears and clutch. Wish you the best!

Hi Ralph
Many thanks for your comments. I’m not using the dealer, haven’t since expiry of the first 5 yrs covered by passport & warranty. I have a number of excellent mini specialist (independent) garages locally. The clutch was replaced some 2 years ago & covered by extended warranty. The leak etc clearly identifies gearbox, not clutch.

the later box as yours is is better but not as good as 6 speed boxes, i would change the oil in it and add molyslip gearbox additive can help keep it happy for longer link below
