is there any adjustment on the ca18det clutch slave cylinder????? ever since changing the gearbox the clutch seems to be dragging until warmed up to about 160degrees. if started in gear with foot on the clutch, it will pull forward and can't change gears til hot. i used the slave cylinder that came with the new gearbox but was fine before ????? the oil is a 70-80 which is suppose to be the right spec and was fine before ....... can i adjust it at all? ?????
