[Healeys] OD Design Flaw? (was Munched Overdrive?)

[warthodson at aol.com]

As stated previously, the mechanic is wrong. A properly set up overdrive will
drop out of overdrive (even if the OD switch is left on) when first, second or
reverse gear is selected & will also drop out when the ignition key is turned
off, even if the OD switch is on & the transmission is in third or fourth
gear.
