I have not had any experiance with the "switch pitch 400" tranny i have a tranny out of a 64 Riv. My question is how do you identify the differance from a 400 and a dynaflow
it should have a tag on the pass side (mine was blue). there is a plug near the bottom just above the drain plate. it has two contacts one is a __ the other is a l. the bottom has a indent like a shoe heel and i think 3 circles out side the shoe heel.
