I am trying to figure out hoy to tell the difference in these auto trnasmissions: A340E, A340F, and A340H. I think the H has a removeable bell housing and you can use an adapter for a chevy v6.
How do I tell? I have an 85 EFI truck with a longbed. I want to do a 4.3 swap and I am hoping I can use the stock auto transmission. (ist my DD, not my trail rig).
