2nd To 1st Faster Than 20km

[Twitchy]

Quite sure its a syncro problem, cant change from 2nd to first over 20km/h less i do some very specky double the clutcing and then only some times it doesn't grind. Guess i should confirm that, was wondering if any one else has had this problem and what it costs. This is for a mate of mine, the car is an r32 gtst.

Cheers

[chinkeboi]

?... i cant get from 2nd to 1st even when its like 2km per hour?

[r32woohoo]

i was under the impression that 1st is only really used from a standstill?

ive got a 32 as well n it doesnt go into 1st unless im basically stopped, and wen it does on the odd occasion coz ive misjudged my speed, it takes a hell of a lot of effort to get it in there, n then it throws me forward out of my seat wen u let the clutch out coz the gear is too slow....

[ali-turko]

i can get it in but its hard, the back kicks out and the wheels lock up, y do u wanna gear down from 2nd to 1st at 20ks neway

[PHATR32]

lol, i dont think 1st has a synchro!

[ali-turko]

dat will explain y its so hard to get in lol

[Munkyb0y]

most cars dont shift to 1st unless they're basically stopped.

including, in my experience, r33, lancer, rav 4, ss ute, fpv. the clapped out barina did. lol. but thats another story.

considering i can take off in 2nd with no probs in my 33, why would you wanna shift down to 1st at 20kph anyway?

edit: speeling speling, spelling ><

it sure as f**k won't if you keep trying to put it in 1st when you're moving faster than a crawling pace.

tell your mate to learn to drive. or if he's intent on abusing cars, get a hyundai.

[R31Nismoid]

Tell your friend not to do it then.

There is no need to go from 2nd to 1st @ 20km/h

[Twitchy]

OK, some interesting responses there, all of which i dont think are completely accurate. I have driven this particular car alot and never had a problem shifting into 1st ready to take that hair pin, now it dont go.....unless i basically grind it into oblivion. Not sure what cars you guys drive, but all cars i have ever driven, including my own, go into first from 2nd at speed at which 1st is capable of easily. Any way this particular car used to, now it don't. My guess a gear box re-build or new one, Cost??

[siksII]

its just a worn synchro, the vast majority of skylines are crunchy into at least a couple of gears, simple solution to the first question, just learn to double clutch perfectly into 1st from 2nd and u dont need synchro or a new gearbox, mine is the same.

[RANDY]

I'm wondering if I should try this on the way home...!

I can't recall any manual car i've ever driven of happily shifting into 1st unless the needle doesn't register on the speedo!

So you can do it in your R32 GTR, and you could do it in your mates R32 GTST until it stopped working? I'm no "Dr Gearbox", but I think for money's sake you should probably stop doing it in your GTR incase it also magically stops doing it for ya. ;o)

[RANDY]

sikSII, are you able to shift into 1st from 20kmph and above?

I have driven siksII's car many times and you can get any car into first if you really want to but as he said you have to double clutch.

If you don't double clutch the synchro is required. Do some research on what a synchro is and how it works and you will realise that everytime you go down gears if you don't single shuffle and match the revs the synchro is being worn.

This is really basic twitchy- it won't go into first when it used to at speed because you have worn the synchro really badly. You were just lucky to have a really good gearbox in the first place that would let you put it into first without double clutching.

Match the revs and double clutch and the synchro's don't get used.

Thanks Twitchy for starting the thread for me and the responses so far..

For those of you abusing me for needing 1st gear.. you guys obviously must live somewhere flat like Melbourne!! I drive in a hilly suburb where I turn off to my street on a 110-degree bend up a hill.. I'm at crawling pace when I go 2nd -> 1st as I make the turn.. definitely not abusing the gear box!

However all of a sudden yesterday it simply won't go in to 1st unless I'm almost complete stopped.. It's new to me but it seems other people have the same issue... Can anyone mechanical shed some light on this? Thanks!

go into the corner faster in 2nd

why go back into first while rolling, even when im gearing down at the lights...second then to neutral

[Race_Bred]

You have a worn 1st gear synchro, my SSS pulsar does the same but only when its cold, you just need to bring the engine speed up to the same speed as the gearbox and she will slide in or you can spend big bucks fixing it.

A mate of mine had the same problem with his S15, he bought some nulon additive which claimed to fix this problem but i havent seen him since we put it in so i can't say if it works

go into the corner faster in 2nd

yep. now, i haven't seen said corner but you *may* need to drift it in order to keep the revs up and stop the engine from stalling, if you leave it in 2nd

if you need first, double clutch the downshift. clutch in, gearbox into neutral, clutch out, rev the engine, clutch in, gearbox into 1st, clutch out. takes some practice but you MUST have your foot off the clutch in neutral or you're just rev matching, not double clutching. rev matching won't save your synchros.

the reason why it's not going into 1st any more is because the synchro WAS healthy, now it is worn and it can't match the revs any longer -> crunch.

As Twitchy likes to say.. "it doesn't shit in its own nest" ... not on my street at least..

Thanks for the comments guys.. I'll see how it goes when I take it for a spin on the weekend..!

change the fluid to some redline stuff as ive heard it works well

gearbox's should be able to change from 2nd to 1st even moving, saying otherwise is rediculous. my rb and sr boxes both do. its a worn syncro so try the fluid trick then otherwise you may have to rebuild it
