I can never get my box into 1st gear >20kmh unless I force it, or I double clutch. At first I thought my box was rooted, but I find that almost any car with any decent ks on it behaves exactly the same!

A good oil change with Castrol VMX 80 will help things.

Not as much as learning how to drive properly

[wreckedhead]

seriously people how dumb do you have to be not to realise that you shouldnt hardly ever gear down into first gear while approaching anything, whats wrong with keeping it in second gear ar 20kph, so you dont have the power of first for about 2 seconds, but who cares, trust me no oil is going to help you in this case, maybe a few more lessons on manual driving, or buy an auto.

Just put the lightweight shock proof redline oil in your hairy box and you can select any gear you like at any time of the day. Some of the best money you will spend on your baby. Order online at www.relineoil.com.au

You need this much for GTR, dunno about GTS

Gearbox -- 4.1 L

Transfer case -- 1.8 L

Rear diff -- 1.5 L

Front diff -- 1.0 L

out of curiosity what is that 1% of cars that let you go into 1st?

driven so many cars i cant remember.. i know some em do.. although some less willing that others I usually only try on the shitty cars anyway.

learn to do heel and toe if u wanna down shift to first gear, you cannot downshift to first gear without matching revs as i believe first gear do not carry synchros with them.

[Zahos]

thats funny you all say that, coz i get into 1st quite smoothly < 15km/h if I double clutch and rev match... it almost goes in itself.... (if u need to know why, think about coming to an uphill intersection, and just as you're about to stop, the lights go green)

I haven't really tried anything over that, coz like most ppl say, u dont really need to....

But as a general rule of thumb, if it struggles to get into first gear while moving, then dont!

[Merli]

Zahos: Well obviously, because that's what double de-clutching achieves, but all these people aren't doing that, and are just trying to force it into 1st gear.

Also, that scenario falls into the 0.05% of times when you'll need to put it into 1st gear whilst moving. 99.95% of the time, you should never have to put it into 1st gear whilst moving.

Umm i know this sounds stupid,

but how do you double clutch?

All my friends do it, but fu*k, no one is willlin to teach me how to ....

grrrrrrrrrrrrrr

[ferni]

Guilty - don't feel stupid - chances are if your friends won't teach/tell you they probbaly don't know what it is..

Double Clutching

First of all let's deal with the "double declutching " issue. This is really only the British term for 'double clutching' and makes reference in some way I suppose, to the fact that it is usually a downshifting maneuver in disengaging the clutch. The first stage in a full 'heel and toe' gear change is the simple use of double clutching. On its own this is a fairly simple little dance of the toes and it goes like this:

1. You are driving along in your TR, MG or whatever in third gear for example, approaching a corner and preparing to shift to second. You brake with the left edge of the ball of your right foot as usual.

2. Depressing the clutch with your left foot the shift lever passes through neutral as this happens you release the clutch pedal out again half way, thus setting the mechanics of the clutch assembly in motion again.

3. Then fully depress the clutch to complete your shift into second.

That my friends is a double declutching. It might sound odd in print but is quite simple in action. Practice it in the driveway, with the engine off so you don't hit anything. The aim is to keep the engine and the clutch plates turning at the same speed for the moment when they engage themselves. Your car will thank you especially if you have an older vehicle that lacks effective synchromesh.

I learnt to drive on my Dad's old 60's Alpha and the syncro on 2nd was so bad you have to double clutch in and out of that gear... with no power steering, peddles stupidly close together and an accelerator that only moves about two cm and its on the floor...

it was a tough learning machine... but fun and sounded great...

Skyline gearboxes won't let you select 1st while moving just like it won't let you select REVERSE... there idiot proof... (unless you are the kind of idiot who just forces it anyway)

[gatty]

thanks very much for the flames....

rather then stopping at busy roundabouts i usually try to keep a slight crawl on the car, otherwise i'll never get in when chance arises, so i hardly come to a complete stop..

ad i haven't been forcing it...has happened twice (crunches) so now i just leave it with slight pressure until i drops in itself, i may try the ouble clutch method - but this is not a everyday driving thing...just a few intersections up here that are always busy etc.

Okay, that's a valid time to be putting it back into 1st whilst moving...

Just make sure you're going *really* slow, like at a crawling pace, and double clutch it, and you should have no worries!

[Terminal]

hehe, heel toe. i thought that was just a thing from Initial D, but then i tried it one day and it works wonders.

[_turtle_]

gatty, as everyone else is saying u shouldn't be shifting into 1st unless ur stopping. not sure what speed ur going at, but it usually helps to shift to 2nd and then wen ur nearly at a stop push it in first. most cars have this point where 1st will easily slide in going at a certain slow speed, eg. for me wen the car is just about to stop and its still rolling i find that it will just slide into first easily.

[Guilty]

oh thx..gonna try that tomoloz

hahaha

umm does double clutching work when you shifting up gears?

does it have the same effect?

[Guilty]

oh and one more thing, does double clutching burn the clutch?
