[TR] Overdrive woes

[chuck easton]

Greetings

I have been trying to troubleshoot a TR6 Type J overdrive for the last couple
of days. It's in a '73 and the electrical circuit is set up with a relay
similar to earlier models. The problem is it cuts out when changing speed.  I
have replaced the relay and the transmission switch. The column switch is new
and seems to work fine. I have not touched the solenoid. I hooked a light into
the circuit at the solenoid and when it quits the solenoid is not getting
power.

Running down a highway, everything works fine. If you slow down for traffic or
drive around a residential area it will quit and wont work upon returning to
highway speeds. If you leave the column switch in the on position the
overdrive will engage after periods of time ranging from hours to a couple of
minutes. If anyone has resolved a similar problem I would sure like to hear
from you.
