Just recently with the colder wheather in my area my converter won't lock up like it use to. It normally locked up around 37mph and now it fights to lock up at all and when it does it unlocks very easily. If the Transmission runs to cool could this affect it? I noticed a change in the car when the cold wheather came but I also just installed a 224 cam and a LS-6 manifold and the converter is acting the same if not worse any reasons she won't lock up? The car does act a little better after it heats up.
