The wires were always breaking inside the gear lever?
And the solenoids used to play up. MarkModern cars, Its all wizardry and witchcraft

First thing to check is gearbox oil level,also check operation of inhibitor switch on selector housing,accessed by removing gear lever gaiter.The switch should have continuity in 3rd and 4th,and be open in 1st,2nd and reverse.

Ok, thanks for replies, the overdrive switch is on the dash and proves good,as for the inhibitor switch I tested this one by bypassing it, making certain not to select reverse with overdrive engaged. The problem of sometimes slipping overdrive and occasional non engagment, and sometimes not disengaging remained, although this switch is slightly faulty as it occasionally has closed circuit in first and secound positions. Am going to check filter today, and have also read about clutch remains trapped here, and the need for regular oil changes. Solinoid faults, I think we may have an issue here as this car pops and backfires occasionally when overdrive is activated, could a faulty solinoid draw current away from the ignition? Cheers Phrom fill.
