[Healeys] overdrive problem

[David Porter]

Well, actually that is the job of the throttle position switch on the firewall. If the OD is engaged, mashing the gas pedal should make the OD to drop out.

Sorry, but the Laycock deNormanville overdrive is not supposed to kick down automatically. The most common fault that causes the OD to drop out is faulty o-rings on the accumulator sleeve. This won’t allow the OD to build full operating pressure.
