5 Speed

The Volvo has a M47 5-speed manual transmission.  These are pretty rare as they were optional equipment.  The gearbox takes just under 2 quarts of Type-F automatic transmission fluid.  I drilled a hole in the bottle cap and inserted 6' of clear plastic tubing and got my wife to hold the bottle up high and squeeze to get the fluid to go into the transmission.  Cheaper than the $18 fluid transfer pump at the auto parts store!  I was happy to see very little in the way of metal bits on the drain plug magnets.  To fill, fill to overflowing out the top hole.  Both plugs are removed with a 13mm box wrench.  Replace the copper washers or heat them to red hot and reuse.  Evidently, this particular transmission does not have much in the way of extra fluid in it.  If it leaks, make sure you check the fill level regularly.  I have known of two transmission failures resulting from lack of fluid.
