I dunno, we couldnt figure it out and we ended up taking it to a mechanic to have it fixed. It was on a 2003 celica. He installed a stage 2 performance clutch and ever thing seemed well on the install but then after test driving it would still slip and grind in between gears...BUT you should be alright with that step by step guide. His clutch was grinding like crazy though, i have no idea why but i know it cost him $150 to get it done "correctyl" which i think is that the original price to put a clutch on anyway.
