R34 Gearbox 5Th Gear Synchro May Need Replacing

[Aggroman]

myself and about half the skyline world (not literally but a damn lot of us) run the lightweight and swear by it..

Dont use the heavyweight because they are not reconmended for synchro boxes are are more for extreme applications like mech LSD's, dogboxes etc

Thanks again for your pro advice David I really appreciate it.

Was only wanting to go heavy mainly because I dont want 2 hear the crunch or get the resistance (which hopefully guranteed to stop it with heavy). Just didnt want to go putting in lightweight and then having no improvement and needing to get heavy anyway.

I wonder if there is anything wrong with skipping lightweight and jumping straight in to heavy when all other synchros are fine? Maybe a conversation for another day.

What threw me off is that when I read about the lightweight it says "It has excellent low-temperature flow which allows easier shifting when cold." and my box is fine when its cold its when it warms up a little bit and you see the fault.

Will take ur advice and go lightweight though.

And was also thinking, when i do put the lightweight shockproof in.

After draining the existing oil, would u guys recommend completely cleaning / flushing the box out or is this not really necessary?

Hi every1,

I got redline lightweight shockproof today and put it in my box. Since then the resistance, crunch, vibration in to 5th has stopped (touch wood) and every gear seems so much smoother.

Just wanted 2 say thank u 2 every1 that helped with this - Aggroman, N1GTR, GTRsean, BOZ22N, zebra and fatz. I really appreciate your advice thanks so much.
