Float shifting

Is float shifting likely to cause any damage to a IIA gearbox? (obviously provided it's done properly). These boxes seem to float very well on the face of it.

I've heard you shouldn't float syncro boxes though. Any thoughts?

I don't see a problem if it is done without crunching the gears or the syncros. I have been doing it for years with syncro boxes without problems- the ones that feel right I might add. The missus new (to us - 93 model) Pulsar is a notable exception, the gearbox is in good nick, but just doesn't like it.

What is float shifting - I know all about double shifting but not heard of float shifting.

Neither have I but I assume it's gear changes without using the clutch.

Thats what I assumed too by the sound of it. If its not, then my first reply wont make much sense...

If float shifting means clutchless changing, yes it will damage the syncros. The damage occurs when taking the box out of gear, but not into gear, sans clutch. It does not happen suddenly or catastrophicly, but gradually hammers the syncros. It's fine for (non syncro) constant mesh or crash boxes.

never heard it call float shifting....i just call it changing gears without the clutch

i think its a good skill to learn, i drove the last 200km out of the simpson desert using this method as my clutch master cylinder failed

i quite often go to nuteral when coming up to a set of lights without using the clutch
