I.E. shifting without the use of a clutch.

Advice from the folk with more experience than me required. And I know almost everyone here falls into that catagory.

My clutch is on its way so ive been experimenting a bit.

Can feel my way in and out of 1st, 2nd but im a bit cack-handed after that.

Is there a formula (I.E. change to 2nd at 2k etc) or is it just grope and fumble like a sat night segs session in a bus shelter?

the large variety of final drive diff- ratio is a bit of a bugger, there isn't a standard for each 300
what helps, is when going down a gear, pull it in neutral; then rev it and gently see if you can select the lower gear..
on going up a gear you'll have to drop the rpm's, but don't give it a chance to idle because that's most likely to low.

downside to the upshifting part is that you stress the gearboxes sprockets and synchro's a lot so i'd definatly want to change the clutch anyway soon or you'll have even more work

1.Thats what Ive been doing with limited success.

2. Thanks dude, I didnt know that about upshifting, I was trying reving higher.
Thats really good to know.

Had to do this myself, I have a vague memory that the rev counter and speedo point in the same angle in 3rd. 4th would be near idle at 30mph typically. You just need a couple of reference points.

A little pressure on the gear lever helps, rev up and catch on the way down if you miss on the upshift.

Once you get the idea (i.e. the revs are lower for a higher gear and vice versa) fumble until you stop being that teenager

What you need is gentle touch and feel, don't force it in, but gently probe, it will fell in when situation is proper.

Getting it out without clutch is easy, just lighten up throttle a bit and gently tap it out.

Now when you start put it in, you put it to 'lips', you can feel how there is little resistance, just keep it on there and when revs are right you feel it easing off, then push it in with determination but without rushing or forcing.

Proper rpm comes with experimenting, but you can get close approximate from diff + gear ratio and of course tire size as that affects it too.

Just remember that from 2nd to 3rd rpm drop is quite large and that with lower rpm it is easier that higher rpm.

Basic idea is to put engine to rpm which it will be when that next gear is in.

You can also do half clutching, which helps a bit, just quick tap to half way when putting into gear, don't bother clutching when taking off the gear as that requires only slight pressure and lift and it will come off by itself.

Hmm, I wonder, maybe I should... Nah, you probably can figure that out yourself

Have you considered buying a clutch to cure the problem??

Clutches are expensive.

Men to make clutches be on a car are more expensive.

I am saving. But a bit of knowledge never goes wrong.

A lot of knowledge would be ideal, but baby steps.

If (and it's a big 'if') you manage to rev match perfectly and slot the next gear in you are doing the synchros out of a job. Thus over several miles your gearbox is fubar'd.

Yeah. Someone else said that too.

New clutch is moved up the list to Next Thing To Buy status.

Fj is cheap is he not?

Gearboxes on the other hand aren't.

Sir, you offend.

How about clutch adjustment?

In some vehicles there is possibility to adjust clutch which may or may not extend life of clutch.

There are some videos to keep you entertained:

Judging by titles those related videos are something that should be essential viewing for anyone having a car, even it is perhaps bit american view to subject.

What are the symtoms Ben? My cav has a crunchy shift but I'm choosing to ignore it.

Pedal is superhigh.
Power feeds in fine gradually.
Boot it and you get lots of increasing revs with little or no increase in speed.
