Hi every one I’m new to this so you will need to be patient.
I have a 1971 Vauxhall Viva 1600 automatic, and I need some help with finding information or if I’m lucky a fix.
The gearbox is a GM THm 180, this gearbox was fitted to many makes of cars of the same period or so I found out.
The problem is that Vauxhall used a electric actuator for the kick down not a cable like every other make , and mine is faulty and the switch on the carburettor missing. The car is fitted with a 2.3 engine from a cf and a manual gear bow.
I want to put it back how it was , I have 95% of the bits except I can not find anybody to help with the detent actuator or switch.
Can any body help even a part number may help , I can supply a picture from the gearbox manual but that’s all I’ve got.
Many thanks if you’ve taken the time to read this , Cheers Rob
