I bought a Speeco phd at TSC today. The transmission comes without oil. The owners manual says to use EP-90 lube oil. I've searched the world over without a solution as to what to get. I called Speeco and they could not tell me what to get either. When I didn't accept this they took my number and called me back. They guy actually told me they called TSC and TSC recommended something I've already forgotten. Anybody have a suggestion? I also called Mobil Oil and the tech asked if it was Gl-4 or Gl-5. I'm familiar with those but don't know what to use. I'm a little put out that the manufacturer couldn't supply me with the info. Kinda makes me wonder if the unit is quality built.
