Not sure what type of tranny, other than to say it is an original 400 1968. I took a pic of the end of the cable that goes into the tranny, but having issues with file manager, it's a 1.95 mb file, not sure why it won't except it. I would assume the issue is something internal in the tranny.
I will find out what type of tranny it is and then try to source parts. When I attempt to take the parts out of the tranny, do I need to drain the tranny first, i.e., will the tranny leak fluid when I try to take the parts out.
