The correct procedure for filling overdrives on the above makes is given hereunder, and should be adhered to as it provides the only safe way of ensuring that proper levels have been reached. (1) Remove both transmission and overdrive drain plugs and also the transmission fill plug. (Although the overdrive housing has its own fill hole, the manufacturer recommends filling through the trans­ mission fill hole only). (2) Drain both sections completely and replace drain plugs. (3) Pump lubricant slowly into transmission, allowing it to feed through narrow opening between the two housings so as to fill overdrive along with trans­ mission. If lubricant is added rapidly under pressure, the transmission housing fills immediately while the lubricant has only just begun to flow through into the overdrive. (4) Allow a few minutes for the lubricant to fill over­ drive. This must not be hurried. The correct level is up to the transmission fill hole. (5) Replace transmission fill plug.

Early 1951 models require three and a half pints for all models with or without overdrive, the same as on 1949 and 1950 models. The difference between early and late 1951 Mercury models is recognized by the position of the drain and fill plugs.
