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

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 :oops:

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
