Re: Oil for rear and overdrive

For the overdrive, just follow Packard's recommendations in the owner's manual and/or lubrication chart. Since your rear axle uses hypoid gearing, you MUST use an EP (extreme pressure) gear oil but that's not a concern as there are no yellow metal parts in the rear axle assembly.
