well,, got another question, if you don't mind. 1979 Traveler, 345, 4bbl TQ, a/c, cruise, p/s, p/b, tilt wheel. hooked up the trans and almost finished with it, getting ready to get it cranked over for the first time. on the TF 727, where the trans. fluid filler tube goes into the body of the trans? just to the left of it, there is a threaded opening. What goes there? is it just a plug, or did I miss an electrical switch? the threads are the same as the engine oil switch that screws into the oil gallery of the engine block. appreciate the response, and thanks.
