Stag overdrive wiring

[Eric990j]

Hi all, before I get stripping the insides of the car, is this the best way to check the overdrive wiring as I have something intermittently faulty with the engagement and suspect a wire or connector. Can I do it from underneath?

There is an inhibitor switch hidden on top of the gearbox, this stops engagement in 1s 2nd

if its a J type the solenoid piston may be sticking or need new O rings
needs a thin 1" af spanner to remove it
theres is a small 10mm circlip in the sol end, this needs removing to tap out the inner spool valve piston
for a clean up.


You can check the feed with a bulb connected to the solenoid terminal

J types dont have a relay, just the gear knob switch and inhibitor switch
wiring down the gearstick is a common failing
use silcon wire it takes the heat better

Thanks Pete , it's the later gearbox so I'll change the wiring. Nice to get confirmation before I start.
