Whenever i change from 3rd to 2nd above a certain speed (about 25mph) it always grinds. does anyone else experience anything similar, or have i got a worn out gear/synchro?

Ive had 4 manual Minis. (well, 3, but one has had 2 engines)

And all 4 engines Grind from 3rd to second when I was giving it some.

I usually Just double clutch it, it sounds racey too. :D



For those who dont know how to double the clutch, Then its simple enough.

Clutch down,
Into Neutral
Clutch up,
Give it a rev
Clutch down
Into 2nd
Clutch up
away you go


Sounds complicated, Ive got it down to a Tee now, Been driving like that for a bout 6 months. I can now also heel / toe it too, So whilst im engine brakeing, I can also Hold the brake pedal with my heel, and give the throttle some revs to allow me to double Clutch it to down change to 2nd.

people must think Ive got like 3 legs when they see my brake lights on AND hear my throttle go Vrooom! :D


But yea, I wouldnt worry too much about the grinding to be honnest. Learn how to double clutch and you will have NO problems what so ever. :(

You can change gear in any car without depressing the clutch, as long as you can match engine and road speed.... but... you will wear your gearbox, as more often than not, if you are pressing on you will miss and grind the gears. It is the dog teeth on the gears you are grinding and not anything else, so rebuilds would immediately become more expensive as a rebuilder would not accept your box as an exchange.

Best thing to do is get another gearbox, off ebay or such like, and then get it rebuilt, if you can't have you car off the road for any period of time.

Just for the record, IM not Clutchles changing!

Just incase thats what your saying. I Can Do it, Ive tried, and if you can get a good speed Lineup, then clutchless changes are ok, But I dont really feel comfortable doing them.


Double clutching is Different. Call me "mr State the obvious" but It sounds like some of you think Im clutchless changing.

in my defence the clutch is very worn and the gearboxis on it's way out which is why i tried it to begin with as the engine gearbox is coming out soon anyway :D

So the grinding is a bad thing I just thought I was shifting into 2nd at too high a speed as my speedo doesn't work.
