Gear Box Issue

[bradley]

just wonder guys i need your help on this one. i have a problem i own a skyline r33 series 2

the problem i am getting is that i have a gear box problem. the issue is that when the car is hot and has been driven for a long period of time when i stop at a set of traffic lights and the car has come to a complete stop and put then gear in neutral. when its time to go i out the clutch down all the way down and put it in first gear it crunches everytime i do it... So im just wondering if anyone else has experienced this same problem, if you have please i would like your help on this, if anyway else on this forum knows what the problem i would be grateful for your input on this matter

I had the same problem in my R33 GT-R. It wouldn't just happen when it was hot, but all the time. There was also a crunch going from 3rd to 4th at higher revs. I sort of got used to it and all I would do is have my foot on the clutch for about 2 seconds before I put it in first; then it wouldn't crunch. Not sure if it's definitely related to the 3rd to 4th issue but I was considering putting in some Redline lightweight shockproof gear oil (smurf blood). It's not really recommended for these gearboxes, however many have used it in R33 'boxes that are showing signs of wear and they swear by it, saying it made a huge difference (all of these accounts are what I have read on this forum). If this is the problem (simply wearing synchros out as these boxes do) then that may help. It won't be a long term fix though.

no the only problem is when its hot and the car has been driven for a while, its when the car is hot. and it only happens in first gear only, and only when i put it in first gear ready to take off, then it crunches when i put it on first gear
