Transmission Issues

[JONAM]

hi guys,

i've gotta a 96 r33 gtst (manual). recently i've noticed that in the mornings im finding it a little hard to shift up or shift down to the 2nd gear.However @ the same time as i depress the cluch it makes a noice as if i haven't already depressed the clutch.But after few gear chnges its fine.i havent changed the transmission fuel since i purchased this car and it has been nearly an year. is that the cause? any thoughts..!

cheers

Sounds like your synchros are shot!!

whatever you do , dont put fuel in your gearbox only put fuel in your fuel tank

What you need to put in your gearbox is...gearbox oil !In your case about 4.2 litres if you drain all of the old oil out!

The bad news is that if your synchros are gone they are gone.

To have a really slippery box like you have on a new car you will have to get the box repaired ( that costs lots of money) or fit a good second hand box ( risky ).. dont even think about buying a new box!!

The not so bad news is that SOMETIMES replacing the oil makes a lot of difference..lots of blokes with synchro problems on their skylines put Redline heavy duty shockproof gearbox oil in and find it stops most of the crunching.

You can get a garage to do this for you or you can do it yourself... if you want to do it yourself then you can refer to the first thread that you put on this site and go to the tutorial that was suggested..its easy..the only thing that is difficult is pumping up the thick oil with the pump( I would recommend getting the syringe pump maybe from ebay or something like that).

I have a nagging feeling that this may be a wind up ..if it is ,youve got me!!..If this is a genuine question then I hope that this answer may help you.

Just try changing the gear box oil. There are heaps of DIY on the DIY forum. Check it out.

For an r33 GTS T, i would and have opt for Redline Shock proof light.

You will need 1 gallon (3.8 litres), and you will use nearly all of it. You will have a little bit left over.

Its not 4.2, rather approx 3.7 litres, not sure where he got that figure from, and street cars are best to use redline shock proof LIGHT (the blue one) not the heavy one.(the yellow one).

I got the capacity wrong...antony Mcgraph said 4.1 litres and some say 3.8 0r 3.7 , dont matter just fill it up until it spills out the filler hole!!

Some people say that Redline light is good ,some say its no good , some say that Redline heavy duty is good , some say no good..the point I was trying to make is that it sometimes doesnt matter what oil you put in ,it will not cure your worn synchros,but it sometimes helps. If you read around the forums any oil anybody has put in has different results .

Redline heavy duty is recommended for problem gearboxes and the light weight is not recommended for synchro type transmissions ( their words not mine) ...also the Redline heavy duty gearbox oil that I bought was red not yellow.

Anyway Im not sure about this bloke, he doesnt know what a fuel tank is !
