Anyone have any idea on what is a LSD gearbox? Coz recently when I wanna change gear oil and come across this terms. What is the kind of gear box for proton iswara LMST?

Also what is the difference between gear oil and manual transmission fluid?

LSD - limited slip differential

looks like this


http://en.wikipedia.org/wiki/Limited_slip_differential

technically, it is jz a device installed inside ur gearbox/differential to limit the slip difference between left wheel n right wheel.... limiting the slip difference will hence increase traction out of a corner without spinning all ur power away...
LSD plays an important part in drifting (for FR cars)... LSD also works in FF cars, especially for those who frequent GRA or trackdays...

4g13/4g15 gearboxes doesnt come with LSD... but powerzone has custom LSD unit for these gearbox...

Thanks for the info. Do you mean that my iswara LMST is non LSD gearbox? and do my manual iswara LMST has differential fluid? coz I read an article stating that diffential fluid is found in rear-wheel car.

ehh. both the auto n manual dont have the LSD le.

as long as ur GB got lsd, u need to use a specific type of oil for it

I see Then I'll use the appropriate gear oil. Do you have idea about rear differential oil? Do you think Iswara got rear diffential oil? If yes, izit similar to gear oil?

not necessarily true. yes theres such a thing as LSD oil. BUT.....

my old B16A LSD gearbox have always used those cheapo generic gearbox oils from them big barrels. never had any issue whatsoever even with my almost nightly drag sessions and a few track sessions.

but keep in mind i change my gearbox oil every 10k km. and even then the oil still comes out clean.. always kena screw from mechanic for wasting money on the gearbox oil

Thanks a lot By the way, do you know about transfer case fluid? Iswara got that kind of fluid or not?

sorry man..first time hearing about transfer case fluid.

wats that?

might be transfer box for 4wd car.

no ur LMST is FWD car the only gear oil u need to worry is ur gearbox oil

I found something. Have a look on it:

Transfer cases are found on four-wheel drive and all-wheel drive vehicles. This gearbox divides the transmission power output between the rear differential and the front differential. Most transfer cases allow the front wheels to be disengaged and spin freely during normal driving conditions. When desired, power is transferred to all four wheels.
Transfer case fluid provides lubrication to gears, bearings, shafts, and other internal components. Heat, pressure and friction slowly breakdown the additives in the transfer case fluid. In addition, small particles of metal may come off the gears as they wear; these metal particles can mix with the fluid. Fluids can also become contaminated with water.

I think you better list down what oils you want to know about. You seem to be jumping from one oil to another.
If you actually took the initiative to at least Google it, you would've known within minutes.

Hopefully you don't come to "What is Gamat oil?"

I guess you got the right answer. Thanks!

there's some difference in oil grade.

yes, u can enter the tracks n play a few session, but any more den that, normal oil u will start to feel the gear starting to get jam.

higher grade oil can tahan heat better and let u go further without feeling of tat stiffness.

but again if u dont go tracking den u dont have to invest in those oil, they are quite exp..

standard LSD oil will do

my cerek air 1.6 auto got lsd .. hehehe

Do you know how much it needs for brake fluid, power steering fluid and clutch fluid change?

u mean $$$???

no idea la bro...dont remember the exact prices. been a long time since i cared about them...usually i just pay the whole lump sum only

sorry..I mean how much volume needed for the brake fluid and power steering fluid if change. Got people say need up to 5 liters just for the power steering fluid if flushing. Do you think flushing is neccessary or just usual change? My car is iswara 1.3.

just normal change is fine...

flushing is just to ensure that the fluids are new...do it like once a year or something...

ive had my kelisa for 4 years and ive never flushed any of my fluids (except radiator) before....and theyre all still running fine.

as for volume....usually sold per bottle for those fluids...so theyll charge u price per bottle. prices vary from shop to shop and brand to brand

Thanks man!!

Added on May 2, 2008, 10:27 amI intend to change my iswara gear oil. When I came the shop they only sale GL 5 LSD gear oil 75w90. I wonder whether it fit into my gear box or not since iswara is a non LSD gear box, and I'm not sure about the GL requirement. I need your comment on this please!

This might be an old thread but I need to ask a few more question on Mitsu LSD:

(1) What are 1-way, 1.5-way, full-lock, semi-lock LSD?
(2) Does a full-lock LSD requires special drive shaft like a semi-lock (on F5M222 gearbox), or can we re-use normal drive shaft for F5M222
