Im abit bored but was just thinking about occasionally while driving my line in traffic (no speeding ^^) at around 3000 rpm light throtle I got these perfect shifts (usually 2nd to 3rd) where the gear would move in so smoothly without that clicky feeling at all. Just wish I could have that at all gears, especially in the morning where I got to shift really sloooww. Anyway do you guys experience this in traffic driving ?

YES!

I've been trying to learn to do that on every shift, but I never can. It's still clicky most of the time.

When the box is warm, and if it is at the perfect rpm, it feels like I coulda pushed it in by tapping it with my pinky finger.

If only I was shift master and could do it all the time.

i thought it was wen the synchros dont have to do the work too, like when the speeds match up, so try and find how much rpm u drop on each shift, then add 900 or 1000 rpm, and try n shift there (so the next gear is only at about 1000rpm wen u let the clutch out)

i been told that shiftin from 3rd to 4th is easy without the clutch, just to slightly lift off and pull back hard. lol, im assuming (never actually done it myself) this works as the ratios are pretty close... well, compared to the difference in lower gears anyway. anyone done any serious damage by neglecting the clutch?

Going up without the clutch is ok (sort of), the real challenge is going down gears without a clutch smoothly and without crunching. It just takes a bit of practice, and lots of crunching.

I spent 10 years driving 18 ton Macks with a 5 speed non synchro box. Clutchless changes are easy enough when practiced, and I used to set my drivers training skills to travel large distances to not use the clutch unless starting off.

I don't recommend it for synchro boxes. Use the clutch.

whats the trick for clutchless shifting? just practice or is there a special technique u use? u must be pretty good havin 10 years with a non syncro box, tryin not to use the clutch for long trips must been fun

The trick is finding the right revs in each gear where everything inside the box and engine is aligned in terms of revs.

I can do it in the cef and the barina but obviously each car is going to have different revs so I can't tell you the ones for the skyline ;)

The trick to a clutchless upchange. As you ease off the throttle pull it out of gear. As the revs drop to the right point just pull it into the next one. Apply accelerator and continue.

Downchange. As the revs hit the right point just give a small touch on the accelerator to unload the box and pull it out of gear. Rev to the right range and slip it in the next one down. All in the timing.

In racing I use a half double clutch for upchanges where, as I back off the throttle to drop the clutch I pull it out of gear and as the clutch disengages it pulls into the next gear. Can take as little as 0.3sec to change. Racing dog boxes are quicker.

Mines pretty hard to get into second when cold, worse at light throttle/low rpm. Shifts smoothly at high rpm and when warm.

I figured it was due to worn friction faces on the synchro cones, you can feel the synchro sleeve clashing on the teeth as you pull it into gear. I was considering trying to get it fixed under warranty....

Anyone replaced a 1-2 synchro on R33 Gts-t box? I've read conflicting statements about the availability of parts.

i found its hard to put it back into first while the car is still slwoly moving (e.g 5k's or less)

the tx3 was a differant story, went into first easy.

Its bad habit of mine when coming to a complete stop, i like to put it into first before stopping so i can take off quick again.

The welds on my clutch pedal broke the other week and i had to drive home without a clutch (only 5mins no stopping). Lucky i was going down a hill otherwise i wouldnt have been able to get it moving.

Mine is also hard to put into first while car is still slowly moving.

Do you guys find it on really cold start, hard to put the gear into 2nd??

Yeah mines the same going into 2nd gear on a cold start its a bit hard but once the gear box is warmed up its sweet as. I put redline gearbox oil in and that helped alot. Before without the redline oil it was heaps worse.

Like everyone when my car is cold it is not good going into 2nd but once it warm don`t matter what gear or revs it smooth as , changed oil to redline few months ago made it better

I think u need "soft hands" for good changes don`t force it
