i dont know anything about auto trannys. i picked up some Aamco Dextron III Mercon fliud (is this ok). the Dextron III Mercon through me of a little since the dipstick says to only use Mercon fliud. How many quarts does it take? i put about 3/4 of a quart in the torqe converter when i mated the engine and tranny. how much should i add? is this the right fluid?
