hi guys, this is my first post.I have a 2002 BA xr6t 5speed manual that is totally stock, my brother(mechanic) and I changed the clutch from the original to an excedy heavy duty clutch, when the car is running it will not select gears,it will select them when it is switched off, when put in to gear then started it wants to take off suggesting to me that it's not disengaging, I thought that the slave cylinder might of been no good so I bought another genuine(total rip off)slave cylinder but still done the same. then tried the old clutch plate with the new pressure plate still didn't work then tried the new clutch plate with the old pressure plate the same again. so then I tried to put the old clutch in with the genuine new slave cylinder but it still will not select any gears.I also put in a new clutch master cylinder and made sure it was bleed properly. I am really pissed off now cause this has been happening over the last month and its not fun pulling out then in the box over and over on the floor. Any help will be muchly appreciated.
