t-350 or t-400 torque converter ID ?
hey guys i bought a reman torque converter for my olds with a 472 and a th400
out of a '69 deville and after spending 3 hours tearing my car to pieces i realized
the buttons were different, my old one is tapered with a nipple at the top
the new one had no taper but had a ridge around the button i have looked at several sources and according to them the th400s used the torque converter that i couldn't use. Do i have th350 torque converter or some rare th400 TC?
