Alan,
Just as Volvo did with their 1800s, 122s and 140 series cars. They
suggested to not use overdrive below 40 mph and that to use the clutch
in either direction if the change was too abrupt.
Even then I don't believe that Volvos were considered cheap cars, nor
were they known for cutting corners. They used the D type and J type
overdrives, both very similar to the A type. Their overdrives were also
on both four and six cylinder cars. The hp rating on the fours got as
high as 130 hp. The 164 E probably had a bit more.
They also did not have a problem with their cars wearing out
prematurely. I believe Irv Gordon now has over 2.5 million miles on his
1800 S.
The difference between manufacturers was just different approaches to
the same problem. History has borne out that the additional hardware is
probably not necessary.
