First of all, Merry Christmas and a Happy new year to all of you!! I have a question: I have a rebuild TH400 and I was wondering if I could flush the convertor and if so, how to do it the right way. I have heard that if you put your used convertor on your rebuild tranny that you put all the dirt that's hidden in the convertor back into your tranny, but that is why there is a filter in the tranny though? I have removed my convertor and stored it in a sealed plastic bag. What should I do, flush the convertor or buy a new one? I have seen one for $60 brand new.. If I have to buy a new one, should I take the stock stall speed in my combo? I have a '72 455 with iron ported heads (performance valve job, bowl work etc..) Crane H218 ( 218 degrees duration on the intake, and 226 degrees duration on the exhaust @ .050) 800 cfm Q-jet and 2.93:1 gears. The car is a 4400lbs '72 Riviera Thanks in advance, Bram
Bram, I believe any transmission shop should be able to flush out your converter. When you rebuilt the transmission, had it failed completely? In that case, you wouldn't want to put that converter back on a fresh transmission. Any metal in the converter will go back into the transmission unfiltered. fluid is filtered at the point it is picked up in the pan. As far as converters go, you get what you pay for. 60.00 for a new converter? I wouldn't if I was you. Get the best converter you can afford. With intake duration of 218*, a converter about 500 RPM above stock will work, figure about 2000 RPM stall.
