Most of the drivers have this ugly ugly probelm of keeping thier foot on the clutch pedal... which results in clutch frying.

you said clutch is slipping but never told us on which gear?
Clutch plates are weak..
To check your clutch plates do the following steps.park your car and pull the handbrake. now start engine and press clutch. put car into third gear and leave clutch slowly. remember you have handbrake on . if car forces to move with handbrake on then your clutch plates are ok. if not then need to replace or checked.
Clutch was fried n replaced with Aisin one... sold the car last year n upgraded to Altis
Every gear... specially in 1st gear
