How do you do that when you need to stop!(Red light??))

My mate did it regularly... apparently the gearbox doesn't last long.

A company I used to work for had a fleet of diesel metrosm as pool cars. All with close to 100,000 miles on them. To speed up their replacement, several people practiced cluchless shifts on them.

Cluchless upshifts were fairly easy. Rev the engine a bit in the lower gear, pull it into neutral, listen for the engine to drop towards the speed needed for the new gear and let the syncro do the work. Upshifts were more tricky, needing you to pull the lever into neutral and give a heafty prod of the throttle to get the revs higher than you needed for the lower gear. The syncro would then let the low gear engage as the engine slowed to the right speed.

pull it into nuetral, stop, turn off the engine, put it back into first, then crank the engine til you're moving again.

it only needs a few turns to get momentum back up again.

i drove my cav with a snapped clutch cable for a couple of days last year. not really a big deal, you just have to be a bit more concious of what's going on 10 cars ahead.

bay parking's not much fun though

Approaching lights balance throttle and pull into neutral. Turn engine off, select first, restart and drive off! This doesnt work on hills, so you need to plan in advance. In fact, its amazing how rarely you need to stop if you try!

Doing it for so long you get very familiar with the engine noise, so you can pick the revs very precisely and save wear. You can even left foot brake!

When I picked my Indy kit up the guys in unit next door were just going out in their Transit that they had been driving for ages with no clutch cable.

It will be easy.......I have bought a trickshifter

easier on a bec than a cec

i used to do it all the time in my cortina, not because the clutch didn't work, but because my gearbox was knackered, and the car was ready for the scrapper anyway. just got lazy really

Don't think sow..

to find neutral you need to plan to shift down all the gears...

also how can you downshift a bec gearbox without clutch...

i'm able to build clutchless upshift meganisms wich cuts out the injection during half a second erso... but thinking about it it already scares me...

In my (maybe limited) experience of doing it I have found its alot slower to clutchless shift a syncro box than using the clutch and heel and toeing on downshift to set the revs.

Dog box is easier and if well practiced its quicker including left foot braking and clutchless downshifts.

With all my bikes, I rarely used the clutch other than for pulling away/finding neutral for either up or down changes. With my old BMW K100 I had to use the aformentioned method of moving off on starter after cable snapped 35 miles from home.

One set of lights was interesting when I couldn't get neutral and had to stall bike on brakes. Back brake didn't work and front wheel kept skipping. Ended up using kill switch
