Hi all,

My 6 speed gearbox used in 4age blacktop have some grinding sound when shifting from 1st to 2nd gear. Most probably the synchro already spoiled. Was thinking of replacing the synchro (repair). How much would that be including workmanship? Wanted to know the average price as i don't want to be cheated by the mechs.

Or should i just change the whole gearbox to japan reconditioned ones? The reason is I heard that once the gearbox is opened, it would probably have problems after that. How much would this cost then?

Thanks a lot

Gearbox can repair? i thought must replace with another better 1?

Can replace the worn out synchro. However, the workmanship cost would be high. So asking for opinions

manual can repair, auto cannot

auto or manual also can repair .. but the repair cost will be same or higher then buy another recond unit.. that why no people take to repair .. but bear in mind gear box after repair although cost higher but perform 80-90% like a new unit .. recond performence depend on luck

Any gearbox can recond, ask for more details 0126777372

Agreed with you.



2nd hand unit is unknown condition. but if repair. u change everything... so its new ...

Nowadays lots of auto tranny repair specialist. Look up motor trader mag. Only don't know how good these fellows are. I guess you've got do a bit of investigative work first!

I was once faced with this also. U either get a used unit with unknown condition or recondition the gearbox for the same price.

1 guy i knew said something quite logical. If u recondition the unit, they will replace anything that is damaged, bearings, gear cogs and such. So basically u are getting somewhat a new unit.

With a used unit, u do not know how much wear it does. And its rick factor is far more than the risk of getting a reconditioned one.

been thru that phases already...

one is thru my kancil turbo (at)... bought halfcut unit gbox.. a year repeated thing happened.. swapped to manual back

one is honda civic es(common issue... need regular change of ATF, 2-3 Engine oil = 1 atf change/flush)... no problem until the car sold <---complete auto rebuild

Thanks guys for the comments.

Went to the mechanic last week and he told me that its not my synchro...my clutch is actually the main problem

According to him, if my synchro is gone, whenever i shift into 2nd gear, the grinding sound will always be there ( not sometimes have and sometimes don't). He also fully whacked my car (with me inside) to prove to me that its my clutch that needs replacing. After 5-10minutes whacking, my gears are totally sizzling hot and hard to move into all gears.

However i do have some doubts...as what i think is, if clutch gone, wouldn't all of my gears have sound when shifting? I do admit that 2nd to 3rd gear also sometimes have sound (but rarely) but downshifting from 3rd to 2nd is the most painful.


He says its confirmed. Clutch need change, synchro still ok. Total damage for kayaba japan racing clutch is rm1200 include workmanship... Then he say no need pay deposit, he order 1st. If i really want then only i come next week.


My ride is a toyota ae101 with 4age blacktop 6 speed manual..

Help!!

Just thought of this, why is it has to be Racing Clutch in first point? I know blacktop is an interesting engine, as well driven one. Even if the mechanic is correct you may just set down with normal clutch system at lower price ?

Planning to use the car for another 10 years as well as some spirited driving. Also, the clutch set have been replaced around 1 year ago for RM505 by the previous owner (guess this is a very cheap set, not sure what brand). Also heard that the difference is quite significant from good racing clutch to normal ones. Also from the mechanic advise, if want reliable, better take japan racing clutch.

Overall, I love my car. So willing to sacrifice to built her up to her best condition as long as I can afford it. But still pain to see 1.2k fly away...

You might have your point there but keep that in mind, racing clutch does provide your clutch longer lifetime but driving behaviour does provide an even longer one.

Spirited driving = Priceless.
Go for it.
