But we need to know the spec oil to see the correct version. Spec oil tells us viscosity range for proper operation of that vehicle. Use the correct fluid viscosty, either would be a great choice.
Search Redline ATF UOA's. I was surprised after 30K miles of useage examples either oxidized or sheared out of grade.
