Engine Drivetrain 1st Gen Cooper Most liked posts in thread: Will this transmission fit my Mini?

This is good advice from a person who can probably take apart and put together a Midlands 5 speed blind folded.

 

The CV joints have a different number of splines....
So more than just a swap...you need matching CV joints.

 

Need a bunch of new parts if going from a Midlands to a 5-speed Getrag or a 6-speed Getrag.
Count on new axles, flywheel, clutch, clutch lines, starter, mount, and maybe shifter box and cables
(depending on the exact box and cables you have now). These parts add up to about as much as the
transmission itself.

It's a little cheaper than going to the 6-speed Getrag, but not by much, mostly the difference
in the cost of the transmissions themself.

 

Not a straight swap, 2006 5 speed is from the Ford KA and needs all the parts above, plus it is not much better than the Midlands. If you use the Mini for regular street use I'd go fix the Midlands. If the box is shifting ok then the input shaft bearing will be on its way out. Just pull the box, get some new bearings and you should be good for another 70,000+ miles.

 

Thanks 00Mini I dream the Midlands! LOL Or flashover604 can go fit a straight cut gear set for a real whiny sound. hahaha

 

True Eric but to help the lad out. Fixing the Midlands is easier. I bet his Mini has done 70,000+ miles so fixed correctly it should last the miles again.....plus who's going to buy an R50 with a dodgy Midlands box? Only me! hahaha

 

but really, don't sell it because the gearbox is talking. Go get it fixed. Damn I should travel the US fixing the Midlands. Strange because I'm from the Midlands in the UK...LOL

 

If I remember correctly it is a straight swap.

 

I thought the 2006 went to a 6 speed or was it a Getrag instead of a midlands.......

 

There is an interesting "How to" in the Gen 1 section of the library. It will give you an idea of the kind of work involved in the conversion that you are thinking of doing.

 

The incorrect-for-that-model trans swap is something we've never done--thankfully. I know other vendor have done it with good results. When I get inquiries about it, I try to steer the owner away from the idea. Ultimately, you're better off selling your car and getting another one with a better trans/motor package, like sell your R50 for a R53.

 

Thanks....just need the gearbox!
