I am in the process of determining how to install a B&M lockup control into my 85EC with 350C transmission. The 350C has lockup solenoid but there are multiple versions of the valvebody. Some 350C valvebodies have only a lockup solenoid and some versions have a pressure switch (or two apparently). I have posted a picture of the six ("6") different valve body arrangements for the 350C. The pic is an excerpt from The Turbo Hydra-Matic 350 Handbook by Ron Sessions. In addition, I have attached pics of a 350C valvebody with a lockup solenoid and no pressure switch. Obviously, which setup I have will affect how I wire the torque converter lockup. I have an 85 305 with 350C transmission. The snow/ice is to deep to allow me to get into or under the EC to check the trans.
Does anyone know what 350C valvebody they have or what I can expect in my 85 EC?
