Cant Get A Smooth Gear Change?

[Italiazr1]

i might be trippin.

but i own an r32 gts-t i havent really driven any other manual r32's so its hard for me to really comment but

basically ever since ive owned the car i find it hard to gear change quickly? for example i need to give it a few split seconds

before getting it in the next gear its not that bad but makes it hard to snap gear's niclely on a track if you know what i mean.

other manuals ive driven are easy as so its not me but i think maybe there could be a problem with my trany?

just wanna hear other guys views. are they all like this?

also been told to shorten the shifter with one of those ebay kits you can get? might help?

not sure mechanic says it is a bit hard to gear change in my car so he's changing oil but i think it was changed recently

does any one know much about it? sorry for the long post. cheers

[Italiazr1]

one other thing i forgot to mention is that it has always been really hard to find reverse in the car you need to pull it right to the side before pulling it back into reverse other wise it wont slot in not sur if that means anything?

[daisu]

Using a short shifter will make it harder as you are loosing mechanical advantage on the lever. It will also wear out your synchros faster. I'd recommend doing the oil change in the gearbox, maybe use something like that redline shockproof?

Just read your signature, if you have that much power and your '20 gearbox is on it's way out, might be time to look into an RB25 box, especially if you intend to be snapping gear changes on track.

id say your syncros are on the way out.... what gears is it? all of them?

[Italiazr1]

yeah thats what i thought. i know that the box will go next but you can always hope i suppose.

just still wanna know if it is normal to find it a little hard to find gears or are most 32's with a good box smooth not sure cause i dont have many mate's with 32's?

[Italiazr1]

its yeah id say all of them obviously alot easier going from 3rd to 4th but 1st to second is kinda stubbourn its really not that bad but its not as good as other manuals ive driven

it almost feels the way a van or a 1 tonne ute is

[Italiazr1]

can you get syncros fixed or replaced or is that part of the box? dont know much about transmissions.

reverse is the very hard to engage.

[bubba]

If it's hard to get into reverse I'd be looking at the clutch, it might not be disengaging properly.

[Italiazr1]

definately not the clutch just changed it and it was the same before..

any more views?

All my gears in my rb20 box are notchy when shifting in. I try to rev-match so its a smoother change

Reverse gear sometimes locks me out and have to depress clutch and try again.

If you want to rebuild your rb20 gearbox, it will be around $900 trade-in.

http://www.japanesegearbox.com.au/intro.html Located in Rowville. Last time i was there they had about 10 fully rebuild rb20 boxes on display.

I think they also said an extra $150 for gearbox swap

Give them a shot if you decide on swapping.

Although with 260kw~ might be better to get a 2nd hand rb25 gearbox as they are much stronger.

Although im in the same position and cant decide wether a 2nd hand rb25 gearbox is better than a brand new rb20 box

Hope that helps

Did you adjust it at all or just threw a new clutch in?

Reverse doesn't have synchros so I can't see how a worn gearbox can result in you not being able to select reverse..

Definately worth it. I was sceptical when I first put mine in.. $1500 is a lot to spend for something you aren't sure is going to work but since putting the 25box in, I don't regret it and think it was a much smarter thing to do than put ANOTHER 20 box in again.

[Italiazr1]

my mechanic replaced my clutch and transmission oil. so im guessing he did all the adjustments to it...

considering there was no engine in the car when he replaced it im sure he had a resonable look inside.

any way yeah i think ima start lookin at a 25 box for the power i have my box wont last long...

how much do you think a 25 box is $1500?

for a second hand one? is that not including labour to put it in?

[brent32]

maybe your clutch master cylinder is on the way out, it could be struggling if you have a upgraded clutch plate.

[PLYNX]

Check that your clutch pedal box hasnt broken some of the spot welds. Happened on my 33 !

rb25 box sells around $1200-$1800 for a second hand one.

You'll also need some slight customizations to make it work in a r32 too, but i think there are several threads discussing this already

I just got myself a 1 tonne clutch put into my 32t and i have the same problems .. usually hard to get into 1st and reverse...but the other gears feel really notchie

mechanic took it back adjusted the clutch and it was fine after that ... you might wanna check your clutch

[Italiazr1]

the thing is it was pretty much the same before i did the clutch plate apart from being heavier on the foot cause its a performance clutch

[bubba]

New clutch, needs adjusting.

Also, my 25box upgrade was about a $2.5k excercise with the full custom tailshaft I had made and purchase of senders, oil, etc. (paid $1500 for a secondhand 25box)
