have u checked your clutch plate? does it feels hard like semi racing clutch or does the pedal kick back when u depress it?

when was the last time u change yr clutch plate?

hi bro..thx..i just converted my auto gbox to this manual gbox..i was given 2 clutches..1 is the normal,and 1 is the custom clutch plate..the custom clutch plate is new..never used before..

the pedal doesnt feel that hard nor kicked back..feels quite comfortable for me..

a friend of mine suggest that i go for a treatment gearbox.change the gear oil,put in the treatment oil+new gear oil,that should solve the prob..

the problem is now,what is causing the knocking sound?most people said its normal..but i'm afraid the gearbox will tertanggal when i'm cruising lah..

this is often the biggest problem
NO YOU CANT fix it on ur own
its time to jack ur car in the workshop to see any exterior damage
if there is nothing, u have to dismantle your gearbox

no one is david copperfield to see whts wrong inside
there are a thousands of posibility
can only be known when u open them up

What gearbox r u using? It might b same thing happend to me last time, since it is a pull type clutch, there is a ring inside the gearbox stick with the clutch cover. Take it out and clamp it harder, the sound will gone or become quieter. I solved this sound problem accidentally ^^, it happend when my mech somehow dunno how accidentally disfunction my clutch when pressing the clutch pedal, then hv to open up the gearbox to clamp bc the ring. Miracle happend, the tak tak tak sound bcome very less ^^. The sound really annoying, it is like a diesel engine knocking sound, lol, really, and yes, when preeing clutch pedal, the sound will gone.

have u checked your gbox mounting aswell?

maybe changing your gearbox could be your last resort,
for now u need to try & error....go to a few wshops to get 2nd, 3rd opinion etc...
if all mech say u need to change your gbox, then no choice, but i suspect
something in your clutch, pedal or pump...as simple guys quoted earlier.
