how much does it cost to fix the 5th gear synchro in the fds transmission? redline did not work. thinking of the kit that they sell to fix it.

Carry trans in - $200 (+ $150 for 5th gear)

Shop does all the work - about $500 (+ 5th if needed)

holy ****, thats alot, could i do it myself. how much is the kit you can buy.



do i really need to do it, can still use 5th, just cant shift fast into it, which i really dont need to because he said it is capible of 143 in 4th, so dont need to race any faster than that.



damn, fd's kick ass

you can shift slow into gear.....kinda just let it sit on neutral while you hold the clutch down and then after a 2 second ease it into gear........ i've been doin it for more than a year.. and the symptons havent gotten any worse.



keeping it in 4th will eat your gas on the highway

twinturbodork 09-12-2003 01:41 AM

yeah, it i probably not worrying about

FikseRxSeven 09-12-2003 01:43 AM

even if the gear grinds a little(and you will grind)....... at least you know that its long overdue for a rebuild or repair

the part is cheap but it requires special tools and a little disassembly of the tranmission

yes eventually it will destroy the gear teeth and the hub set is probably already gone

i just rebuilt mine with a friend. it was really pretty easy actually. we found a great thread on the other forum and we made our own sst's. you need two different bearing pullers and a little pin punch. i made my own pin punch froma screw and a grinding wheel. and we bought bearing pullers buy we had to lengthen the arms to make it fit. we used some aluminum flatbar to make those. probably 30-40 bucks in the bearing pullers..."we bought expensive ones" and about $50 for the synchro and upgraded select spindle from malloy mazda. took about 2-3 days to do it. because we only worked on it a for a couple hours a day. and we were doing a bunch of other stuff to the car at the same time....clutch,tanny/diff braces. anyways here is the link with the write up we used.



later,
