[TR] RE TR3 Overdrive problem

Make sure the solinoid is moving freely and fully, there's a little arm that sticks out the opposite side of the gearbox
and when the solinoid is working properly the hole in the centre of that arm should line up with a hold in the gearbox
casing (can't remember if it's when it's off or on they line up), you can use a 3/8s screw to check.

Not sure if oil pressure affects the disengagement but while you're under there you might as well check it ;)
