I was wondering if anyone had any experiance with auto-rx in their transmission I know many have used it in their engines. My 88 Bronco II with 46k has developed a little bit of a bang shift from first to second and doesn't seem to feel as smooth as it used to. Do you think arx would help this? Has anyone had arx in the trans and the engine at the same time? I'm 150 miles into the clean phase on my engine. Or should I forget the arx and just change the fluid?
