911 advice im on way to pick up my car and they used 1 and half quart zf lifeguard tranny fluid. since my tranny was ripped apart completely thr fcp kit was short. I know propulsive dynamics trans are supposed to use pentosin which the other 7 quarts are, is this a prob or since usually people dont drop converter is that 1 and quarter to half quart gonna be issue. Supposedly the difference is the pentosin is slightly more viscous and trades mileage for performance on stock transmissions.
