What oil to use to stop gear crunching?

**EuroDude** · 15-01-2008 08:22 PM

I used engine oil in my civics 5MT tranny - works fine, no probs.

I believe Honda MTF is quite similar to Honda engine oil anyway.

yeah, honda used to use engine oil for the gearbox too.
but since then, they have changed that.
even for the older models.

check your master cylinder and your slave if there is any leaks that can course it to crunch..

It's only 3rd that crunches
I do assume it's the synchro for it
Though the gearbox was rebuilt 70,000km ago. Clutch is strong

Like I said though I realise it wont fix the problem, but maybe an oil that will help?

Also, the ATF is recommended for that car

redline light shock, or you could even try automatic transmission oil for a cheaper alternative which also work great from what i heard.

Fulli Sik 12" sub woooooofaaaa will overcome crunching problems. just crank it up yo!

once syncrho is gone theres no oil to stop it from crunching.
time for 2nd hand box... or rebuild

lol .. sound like the mechanics that work at my place..
(though we dont practice such behaviour) lol.
gotta love the dodgyness..

=]

lol you noticed it crunched in 3rd .. so you double clutched till it wont stop crunching.. -.-"
cudda saved a syncro by checkin it out wen it first crunched :/

as all replies said.
check syncro.
change oil (flush).
etc etc
i dont know how atf can be recommended for a manual gearbox.
id rather stick with genuine honda products for everything.

IF you think what ATF does, it lubricates gears and bearings, but is also formulated to work with clutch packs etc. There's no reason why it won't work to do a good job of lubricating the gears and bearings in a manual box, the only issue being if it will work with the synchro rings properly. Some synchro rings are designed to work with ATF. I woudn't use it in a box where it isn't specified.
