Dunno if my new sponsors will like that but I'll give it a go

Its more of a good way to make the life of your box longer. And its also good because you can see if there are metal particals comming out in the oil.

Oh and tim if the oil had leaked out of it on the track, chances are it would have mostly washed off at puke when we were out there. There was a Sh1t load of water out there.

there is a posibility this could happen to it, probably not gonna happen after a couple of track days. the oil got to hot, and aparently it smells pretty bad. that box belo saw a bit of abuse :wink:

I had also noticed changing down from 3rd to 2nd was crunching like a bastard so decided to change it.
Looks like just in time 8O

8O You are very, very lucky indeed.
Well done in checking when you did.
And I expect you'll be checking/changing your MTF more frequently. :wink:

These two quotes get my vote for NZH Quote Of The Year.
Perfect slogans for a future NZH T-Shirt each, IMHO. :thumbsup: :thumbsup:

I change my MTF every 5,000km, sametime as the engine oil and oil filter.
The reason I do this is because I use my roadcar for regular trackdays throughout the year.
Along with car club events like motorkhana, bent sprints, and dual sprints as well.

IMHO I do find on trackdays where they restrict you to just three flying laps, plus a cool down.
That Honda MTF is fine.
But with the trackdays like chelles where you get frequent, longer duration sessions of 6~7 laps plus a cool down lap all day long.
I have found at the end of a couple of such trackdays that Honda MTF has lost its signature, well lubricated feel.

So for peace of mind, and the fact I'm nursing a bad third gear synchro with 217,000km on the clock.
I change the MTF every time I change the engine oil and oil filter.
Much cheaper than a brand new Y1 with LSD, that's for sure.

yeah i change g-boxoil overy engine oil change.... which is about every 2-3,000k (usualy wena trackday is coming up)

last thing i want is a rooted K series box and a smoking K series engine

Hehe im lazy and change mine like once a year!
But I have only done 3 track days. Id change it more often if i did more days.

At $80 per change its not fun, (RRP $150)

I have half a bottle of MTF here you can have for bugger all so you only have to buy 2 bottles to fill it up. Y1 and S1 boxes takes around 2.1 litres and MTF comes in 1 litre bottles

[Shadow Sol]

my M2A4 takes 2L exactly 8)

[83r30]

can i use 10-30 engine oil? I have 2 litres of it

I'd be more inclined to just shell out for some MTF, its what your box drinks so may aswell use it

So you're screwed if you spill any

[d16a7]

you can use anything up to 20w50 engine oil.. AS LONG as its mineral.. not synthetic or semi synthetic...

[Coupe-R]

Yeh you can put it in your gearbox alright, but go out for a hard drive and see how your gearbox likes it.

RUN HONDA MTF or similar,

[dc2r_tegra]

I had the exact same thing on my ITR, undid drain plug and about 5 drops came out 8O . Wierd thing is it was mint as gearbox smooth as, no whine, crunches or noise wat-so-ever. Topped it up with honda MTF and never had any issues at all after that.

$80 sam??? ur trade price sucks monkeys

[Coupe-R]

$80 sam??? ur trade price sucks monkeys

actually i think it was $90

As I said the RRP of the stuff I use is $150 for 3litres. So not Honda MTF as this is around $20 a litre?

ATS metal diff and honda MTF=No good!

[[QUIKdc2]]

Did you undo the fill bolt as well?? it tends to drain quite slowly with the fill bolt still in, but not as slowly as you've described 8O

[Horny_Devil]

well tim ed and i are pretty sure the box is stuffed, or something in there is anyways.

had a good drive to taupo this morning (windows down the whole way and ho heater FT and on the second session on the track the car was having trouble downshifting into 2nd and 3rd. took it off the track and changed the fluid to something a lil thicker, didnt help, had a look at the old oil (had been in the car about 400km if that) and there were some teeny tiny metal shavings in it along with a couple of bigger bits of brass. drove it home carefuly and just as we were getting into auckland it started to whine a little bit so we were rather lucky to get it home in one piece. tim is taking the box out tomorrow to have it look at then hell decide what to do from there

[Horny_Devil]

[Coupe-R]

Changed gearbox oil to something thicker to help gear engagement problems????
Backward thinking to me.

Shame about the box, that brass looking bit is probably a syncro
