but the owner won’t like it!!

I suggest checking that it doesn’t jump out of gear to start with . Maybe best to let the owner drive it first (without keeping a hand on the gear lever) and demonstrate that it stays in gear with light on/off throttle in the lower gears. You don’t want to be held responsible for existing worn dogs. They should be cool about that if the box is ok.

Get the 5K ready based on that !!! :smiley:

That the car you were talking about Clive? Good luck!

Thats a good read … and from what I recall about my Mini dog box, absolutely fact … especially this bit

“The damage can usually be felt by the driver”

Provided the box is in good order, don’t give it a second thought. Just be firm with the shift.


lol, re Andy and feeling the damage. I only cocked it once at Donington in an FV donkey years ago but I vividly remember the feeling and thinking fuck thats a bit more than “just polishing” the gears :astonished: :smiley:

How to change the habit of a lifetime. :frowning:
Change up…just lift throttle ,no clutch. :slight_smile:
Change down dip clutch late into breaking zone , no throttle lift. :smiley:

Sounds easy BUT will my tiny brain cope?? :tired:

Me thinks best stick to good old syncro after 55 years of regular changing. :confused:

Seriously Clive, don’t worry about it:

You will adjust to it automatically.


I didn’t even know that it had to be used in a different way I first got into formula vauxhall. It was only after several days that I realised when changing up I was touching the clutch so lightly that it was not actually disengaging. I then stopped even bothering to move my foot(and being pretty chuffed thinking clutchless changing :smiley: ). Changing down is effectively no different. Its a race - your hand and right foot will want to move as quick as possible naturally!

Stop thinking too hard about it and go enjoy the chance!! :slight_smile:

If you go for the swap the gears may not be the only thing needing regular changing… :blush:

You are obviously back home in the UK then Clive?
