S2000 Gearbox issues / plug threading rounded.

**ALPS** · 20-07-2011 06:58 PM

Apparently Ultra Tune stuffed the threading for the Gearbox Oil NUT.. i've seen it. they held it in with silicon the bastards. Carl from Patterson Lakes CRS Automotive put Liquid Metal in its place to hold it in alot more secure. I'm under the impression that i need to get the gearbox oil topped up / changed for clunky noises and hard to select gears. How can i go about getting it fixed? do i need to buy another gearbox? or can i do a temporary fix to rethread it and use a larger nut?

You need to drain the box, drill and tap the hole the next size up, then flush it out with some oil. Then fill and fit the bigger plug.

Or re-thread with a helical or similar and use original plug

ok so a few people actually also mentioned that i should check my clutch master cylinder, clutch fluid? and clutch slave. I don't know where to find them exactly and how to check if they're good or not. Also must mention that essendon honda did tell me i have a leak in my clutch muster cylinder or something. the bottom of my gearbox has moist oil all over it when i looked getting a wheel alignment. i don't have my own tools to jack it up or anything. If i need to invest in some, what do i go for?

if you plan on re-tapping the filler hole id recommend having someone doing it who knows what they are doing.

basically they are going to drill it out to a larger hole and then re-thread it so a larger plug will fit in it.

^ What he said.

Get them to flush your clutch fluid at the same time and check for leaks. Same with your brake master cylinder.

Word of warning though, if they say you need a new clutch master/slave or brake mastercylinder source the part yourself. You can get them much cheaper and quicker from US online sites than through Honda Australia.

I completely agree, but Who can i trust to do this work and not ask me for my arm or leg in return? also needs to be willing to follow that DIY on grinding off the dirt and regreasing the rod with the nippple at the end for the clutch shaft or something. hope you know which one im talking about?

Also, won't this put metal pieces into the gearbox n stuff it all up?
