Hi all.

A few months ago I posted a request for assistance on removing my overdrive=
 and installing a new one. Many advised me to not do it or to remove the en=
tire transmission first.  Me being the stubborm guy I am I didn't take that=
 advice. I am happy to say that with a little thought and a ton of effort t=
he job is done.  Of course being a British car with Lucas electrics I had o=
ther problems after I installed the new overdrive.  It would work fine and =
then stop working and then start working again.  The problem turned out to =
be a faulty overdrive relay.  In the end the only part of the system I didn=
't change was the dashboard (fascia) and the gear shift lever switches. If =
anyone out there decides to switch out their overdrive feel free to consult=
 with me. ([email-masked]) It really wasn't such a nightmare.  The=
 trick was to raise the rear of the transmission in order to clear the unde=
r side mounts and then to lower it back down to clear the output shaft form=
 the tranny.  Just make sure you remove the throttle shaft from the firewal=
l (Scuttle) before you start raising and lowering the engine. The other pro=
blem was the new throttle switch couild not be adjusted to open until half =
throttle instead of 20% throttle. Easy fix was to bend the shaft that actua=
tes the switch.
Although my old overdrive functioned it hasn't functioned properly for abou=
t 20 years. The new one ( a rebuilt unit from Quantumechanics) operates lik=
e new.  What a pleasure.
