A few months ago, I purchased a 1986 SAAB Turbo Automatic to replace my ailing 1980 manual turbo. It has been a gem to drive up until now despite its 220000 Km (135000 Miles) on the clock. It has a 16V motor with a Brog Warner type 37 auto transmission. 2 days ago on the way to the airport (of all places) at 80KPH (50 MPH) the transmission just stopped driving. No forward gears and no reverse... nothing (except Park). There was no loud noises to indicate a catrostrophic failure of any kind. Fluid level is fine, and looks normal colour, although there were some (minimal) amount of metal dust in the bottom of the transmission front bottom cover. ( I have seen much worse ) First thought was the selector but Park still works. There is no oil flowing through the fluid cooler (radiator) and no pressure at the line pressure plug, so I can only assume it is the pressure pump or regulator. I cant afford to take it to get it overhauled and have worked on numerous engines and manual gearboxes but not automatics. Any suggestions ? Where is the fluid pressure pump ? (I would expect somewhere in the Torque convertor housing) Where is the pressure relief valve ? From looking at it, I hope the torque convertor can be removed (or at least partially dismantled without removing the engine. Is this possible ? Any help would be greatly appreciated. Ian
