VL COMMY .Hi guys GOOD NEWS for those who need to know. I fixed my 'white smoke out the exhaust /disappearing auto fluid from slipping auto trans problem' it was the 'auto modulator /vacuum diaphram' got one from REPCO $69 bit expensive but anyhow its fixed.at first i thought the valve seals or head was stuffed,mechanic quoted $1000 to take head off and never said any thing about Modulator go figure! anyway to fix I just disconected vacuum hose and unscrewed old MODULATOR and screwed in new one ,about half a cup of auto fluid up vacuum tube to inlet manifold poured out onto floor!stuffed diapham! While i was at it i took the pan off the auto drained it and gave the pan a good clean before puting new fluid in the auto only lost the fluid that was in the pan about 1.5lt auto took about 3lt to top up .Now the engine and auto are perfect no smoke no slipping auto.So thanks to every one who helped on this Forum i saved a heap of bread and know how to fix this small but mysterious problem and feel bloody good about the acomplishment.cheers Donhomer
well done bruz... saved a heap of cash... try avoid taking it to mechanics... you know the deal... stooges overcharge ya :P
To defend mechanics, they don't over charge. They run a business, and are trying to make money. You are also paying for a professional service. Admittedly there are expensive mechanics out there, but it's all relative, if you can't afford the dearer one, find a cheap one. At one particular dealer over here they have a sign in their service department. It is a prestige european dealership, the sign says "If you have to ask how much it will cost to repair, you can't afford to drive it".
I fixed the same problem of a split vacuum modulator diafram, with advice from this board
