I have an 05 Trailblazer LT & am going to install a tranny cooler. The cooler I bought says to disconnect the tranny line from the radiator & insert one of the threaded connectors that are provided in order to connect one of the hoses. There is also a threaded connector that is to be connected to the original connector on the line. Does anyone know the size of the transmission lines? The cooler comes with a 5/16" connector & another that I have not been able to figure out the size of.
