As would I ...
There is no current back-fill correct chart that I know of. What I was implying is that one must read the OWNERS MANUAL for his exact year car and go by what FORD
now recommends to use as back-fill.
FOMOCO used GM formulated TYPE A from 1951 to 1957, GM formulated TYPE SUFFIX A from 1957 to 1959. FOMOCO then formulated its own ATF beginning in 1959. The correct fluid for use was FORD TYPE D (1959/ ). It was replaced by TYPE F in 1968. There was no DEXRON (GM TRADEMARK - 1967) usage except for a short period in the early seventies. GM FLUID before DEXRON was introduced was TYPE A or TYPE A SUFFIX A.
What you are seeing now is a refiner attempting to offer a fluid that is supposedly compatible with either application, its description as being MULTI-VEHICLE. MERCON is a TRADE-NAME that FORD began using in 1987 so that throws more information into the fray. Then correct formulations and license has long expired. A seller can put anything on the label that will help sell the product.
The same goes for PS FLUID. You use what the OWNERS MANUAL or a FOMOCO LUBE CHART (of the period calls for).
