I recommend FEO ( honda oil ) for your engine and MTF in your trans.
hasnt let me down yet.
you can try to change the oil in the gearbox, but you may have to live with this if your not willing to spend alot of unessasay $$$$.
there are a few tricks like
- dont have your foot on the brake and hand brake off when you select 1st ( as long as its safe to do so)
- go into another gear then try 1st
- double clutch.
make sure your pressing you clutch in all the way. also make sure your clutch is working as normal. also no air in the hydraulic clutch system.
is your clutch slipping at all ??
cheers

This happens to me as well when it is cold in winter.
First gear is a bitch to get into, like something is blocking the gate.
In warmer weathers or when the car has been driven for a while it tends to get easier and smoother.

Honda boxes can be a bit of a bitch when cold.....esp 2nd gear in dc2s and egs.
If its grinding some gears......could even be your clutch not disengaging properly

Is there a simple test to apply to determine if the clutch is not releasing properly?

maybe try this - Put it first gear with the engine on amd handbrake up- and SLOWLY release the clutch with normal revs...the car should gradually ease forward. IT shouldnt be sudden or "jolt"...

I think ben's confusing clutch wear with it not disengaging properly.
Do you only have problems with first. Is it that you can't get into it or it grinds/catches sometimes?

It is hardest with first, though second is a tad stiff as well.

double clutching works for me.
just be gentle on your box and don't force her to do anything she doesn't wanna.

What is double clutching and is that bad for the gear box?
How can i describe this issue to the mechanic when i bring the car in for the next service? Problem is i cannot demonstrate the problem because the weather is much warmer in Sydney than Canberra.

Well, double clutching just means you put it in, move the gear stick to neutral, release it, then push it in again, then select your gear.
Double-clutching is the proper way to downshift at speed without placing excessive wear on the transmission's synchronizers. This allows you to select a much lower gear without the tell-tale lurch you normally get when the clutch is let out after downshifting.
When downshifting your car from 4th gear to 2nd at say 70 km/ h, you need to raise the engine speed to match what speed the gears will need to be going. To prevent excessive synchroniser wear, the clutch is depressed and the shifter is moved to neutral. The clutch is then released, and the throttle is depressed to bring the engine speed up to where it needs to be for the lower gear. The clutch is then depressed again and the shift lever moved into the lower gear. When the clutch is released the second time, the engine is already turning the proper speed . While this sounds complicated, it's easier done than said, and only takes about a second.
To better understand how the process works, a little background on transmission fundamentals will help.
A typical transmisson has two shafts, one connected to the engine through the clutch, and one connected to the wheels. There are usually four to six sets of gears on these shafts and they are selected with the gearshift lever inside the car. When changing gears, the clutch is depressed to disconnect the engine from the transmission so there isn't any stress on the moving parts. Since the output shaft is permanently connected to the wheels, the only way to match the speed of the two shafts is to use the throttle to adjust engine speed.
Once the engine is turning the right rpm, both shafts will be turning the same speed, and the gear lever will fall into gear WITHOUT using the clutch! (Although most of the time you are shifting too fast to be that accurate)
I cant find the link that I used to help me.

That's actually rev matching.

That's correct except for the bit in bold.....which is also rev matching.
But overall as said by Luke :thumbsup:
There've been a few threads on double clutching already.

agreed, it's rev matching, but most ppl don't double clutch when getting into first do they?

Nope! Shouldn't go into first unless you're pretty much stationary.

ok, I was a little worried I was distributing dis-information.

That said you can get it into first at upto 30Km/h if you can rev match good. But it's not good for your tranny unless you do it properly. I used to do it in the civic because 1st and 2nd gears are the most fun :D Not recommended though unless you can rev match properly!

double clutching.?? jesus.. dont u guys heel and toe?? that is a much easyer way when u slow down .. clutch in rev n brake at the same time then release the clutch out so u dont get that jerking engine braking. just a tip boys..
ok for the original post it seems ur having some trouble with ur gear box.. top up the oil n all that c how u go if it crunches on higher speed changes, that means ur syncros are on the way out..

double clutching is useful for getting into gear...
heel toe is just rev matching or double clutching when u r breaking...
its usually harder to get into first gear, if u dont double clutch and wanna get into gear... and ure going fast ish then just use medium force and push it into gear and keep the force (wait for the gearbox to slowly speed up) and just wait for the gears to engage. This will usually take 3-5 seconds (say if u're going 30-50 or so) if u dun wanna wear the syncos too much. If u wanna engage the gears quicker then 3-5 seconds... (which is quite pretty very long) then learn to double clutch... match the revs when ure in neutral with clutch engaged then disengage and get into gear.
If u have trouble getting into every gear (like me) then maybe something is wrong with the pressure plate... its like driving with the clutch still a bit engaged even if u fully step on the clutch... then it needs repairing...
hope this helps
