i put a new 13inch clutch along with flywheel about a month ago. it was the miles and the pump mods. my problem is air in the system. i put it back together and running i had a hard time with reverse and 1st. so i was told i had to replace the whole system. it cant be bleed. so i took the cyl off the bell housing and pumped it in and out about 10 times,well it worked like new ,now today the air is back. so now what do i do?has anyone else had this happen?it was perfect before it just slipped bad. how much is the whole system?and where to get it cheapest but still good stuff?thanks
