Anyone know production figures, and current existing cars, for automatic transmission 1972 Opel GTs? Thanks in advance.
how rare is an automatic trans in a 72 Opel GT?

I cant say I know exact numbers for you. Hemmings.com has an opel area that has a year by year fact sheet though. I think the download is even on here somewhere. IMHO I would say that yes, manuals are by far more common, but I wouldn't call an auto trans *rare*... unusal I guess is more what I'd say.

I wish they were rare, because I just traded for one yesterday.
Just traded for one yesterday, but when I went to hook up the battery, wires began to smoke so I pulled it off quickly. Don't know what to do now because I just got the car and don't have any manuals. Guess now it's time to hunt a repair manual.

Try removing all of the fuses, then put on a pair of good thick gloves.
Connect the battery again and watch for smoke.
If no smoke appears in a few seconds, install one fuse while wearing thick gloves and watch for smoke.
Repeat until you identify the circuit causing the smoke. Disconnect battery, quickly.
Consult available circuit-based electrical schematics for the affected circuit, to track down the area with the problem.
(The auto trans also has a separate circuit which doesn't appear in many books).

OGTS has a service manual available. I don't know how good it is but they have it. I'll be ordering mine soon enough.

FWIW, I have a 72 with an auto...
As for the smoking wire thing.
First thing is to chase the big battery cable all the way to the starter. Takes less than 30 seconds.
The passage through the firewall is a place where those cables wear through.
The rest of the car shouldn't smoke because theres SUPPOSED to be a fusible link between the starter cable (AKA main battery cable) and the rest of the car.

Along with a nice section on the automatic transmission. Real color coded pages and schematics, highly recommended. Good luck with your wire smoking problem. Also keep in mind the front head light wires are a known problem with shorted electrical wires, they will need to be looked at. Nice looking car, best of luck with her.
Close, but instead of installing one fuse at a time install a test light across the fuse terminals instead. With the key off the light should not come on unless the circuit is going to ground. This also makes it easier to "wiggle test" the harness to find where the short is. A seat belt buzzer also works very well (or maybe even better) for this.

Wha....? Wires on an automatic trans in an Opel? The only wires related to the tranny are in the gear selector for the ignition lock out, reverse light, and some light bulbs.
Please try to tell us which wires were smoking. Was it the battery cables themselves? That would be one ferocious short to get them babies smokin' before any other wires in the car melted through. This all sounds like a headlight wiring short circuit scenario.
Ed, the headlights in these cars have a catastrophic flaw in them and many a GT has caught fire due to it. The headlight circuit has no fuzes and the wiring they used from the radiator to the headlights loses it insulation and shorts out. If your headlight are up, then the lights are on. There's no switch in the car, microswitches in the headlight rotator mechanisms close the circuit when they are up. The vinyl insulation used on those wires dried out in just 10 years and would crumble to dust allowing the wires to touch each other and create a massive short circuit. EVERY GT needs those wires replaced or checked out to see that they have been replaced before you do ANY other repair.

I fully agree and will add an additional motivation for redoing the wiring, redoing them with a properly fused circuit using relays and as short wires as possible will provide a ton of power to the headlights as the voltage reaching them is a lot less than it should be the way they're wired from the factory and you'll notice a *huge* difference when driving in the dark
