Synchros/Gearbox overhaul

d_stroy_r · Post by **d_stroy_r** » Fri Dec 24, 2004 3:46 am

Hey guys, this topic has been going for quite a bit, but i still havent found a solution.

My 3rd gear and now it seems my 4th gear synchros are going.

A had a person say a gearbox overhaul is needed but that costs $1 100.

What's the easiest way to fix this problem?

Is there anyway you can strengthen the gearbox and fix the synchros for under $1k?

Thanx Guys

Hey, cos I learnt to drive a manual in my FTO, my gearbox aint 100%.... So umm noob question, how do you know that they are going?

sycnro's on the tip are different...

on the manual it will be hard to get it into a gear (normally 2nd) ...

on the tip the problems are a little bit more serious, and there is a good chance the clutch is dead as well...

So, if mine crunch from 2nd > 3rd if i shift fast what would that be? If i take it slow then they don't but the shift was a lot faster before...

Umm, sorry for hijacking your thread. i'll go away now

yeah sounds like it to me....

put the redline trans fluid in and it should make your syncro's feel a lot better until they're screwed and have to be replaced.

Hows does unique motorsport fix crunchy gears aka synchros on manuals?

How much does it cost to strenghten gearboxes?

A lot.

Depends on what extent you wish to go, a combination of peace of mind, expected horsepower output, clutch choice and funding.

If you were completely paranoid like I was with my last car (Liberty RS Turbo) you would replace all the synchros (I believe Mitsu use doubles as standard on the FTO) and have all the gears shot-pinned and crack tested, replacing any gears that weren't up to the task.

It's been a fair few years since I had it done but I wouldn't expect much change out of $2k?? if you didn't need to replace any gears.

Cheers
