I am changing out the wearable material in my gearbox and have fitted it back in car. However i have no drive forward or reverse. I had forgotten to hook up the manual control valve to the gear selector. Fixed that and expected my gearbox to work. No ...still no drive. The only thing now i can think of is i replaced my front clutch with a set of 4 inner friction and 4 outer steel plates as that is what i counted when i removed the old ones. I now remember reading here that the front clutch packs are 3 or 5 of each plate. Have i put in one too many ? And would this cause my problem?
