Hi yah Mike...I decided a long time ago to not be afraid of automatics and began by tearing apart non working ones to see whats going on in there...Besides I scored on a lot of really good capscrews...I never got real into overhauls but I can do a lot to them..and there again I can smell a rat when I do have to go to a transmission shop..I've smelt some really big ones around here!!!...There was a guy and his wife that screwed so many people that if you even mention their shop weapons appear and its like "OH YEAH YOU SEEN THEM TWO SOBS?????......TALK BUDDY TALK!!!!!...OK OK its not quite that bad but pretty close..They skated from the area one foggy night...Slithered to some other hole somewhere...Speaking of castiron powerglides.I came across a nice 58 Nomad (ho-hum in 58) but a cool car.It was pouring ATF out the front seal. Well...thats what the tranny shops said..After two reseals the owner parked the thing and sold it to me for twenty five bucks..I figured the front pump nose of the torque converter was screwed up so I pulled the trans and remembered the torque converter lid was bolted together .not welded...My radiator pressure tester fit the hole of the nose..The seal was leaking!!...The local parts store had a box of five in stock!!!!!..I had to buy the whole box....$5.25....I sold the car for $800.00 and it left for the San Juan islands north of here never to return...The seal was like an O ring but square and fit into a groove...I also scored on a later powerglide that the weld was leaking on the converter.....Al...
