The easiest way is to fork out $1299 plus shipping to OGTS (Opel GT Source --- Welcome) and get the "complete" kit, including the auto tranny cross member, adaptor mount, shortened drive shaft, modified shifter, and some other stuff. Simple as pie. Only a LOT of pies!

Or, you can pay them $599 plus shipping, and get a used, unmodified Getrag 240 (which is the model you need). I have also seen a few on German ebay (eBay Deutschland – Der weltweite Online-Marktplatz ) or more specifically try the search at eBay: getrag, Automobile ; There are four there right now for under 180 Euros (same as in $US). But make sure the bellhousing is designed for the Opel CIH engine, either 4 or 6 cylinder. But shipping it to the New World might require the assistance of your cousin Hans in Germany, and a bunch more Euros.

Then modify it using the instructions found at:

Getrag 240 Mods

There is another shifter version, by Gordane, at:

Here is a picture of a Getrag 240 currently on German ebay:

And a Getrag 265 version, which is bigger, has a separate bellhousing, and a different shifter assembly:

Getrag 240 or 265?

Is the first picture I posted (with the integral bellhousing) the Getrag 240, and the second (with the separate bellhousing) the 265? I wondered what the difference was, although they were both listed on ebay.de as being from an Opel CIH engine.

I was under the understanding that the 240 output splines matched the Opel Automatic, which in turn was "standard" corporate GM. And since the automatic driveshaft was too long, it was just as easy to get your 4-speed driveshaft shortened with a GM tranny spline. And the input splines were the same as the stock Opel 1.9 CIH clutch disc, and hence the same as the GM S-10 clutch disc.

So what input and output spline does the 265 have (if different from the 240)? It would seem odd that Opel would have different input splines within the same engnie range, unless it had one for 4 cylinder CIH engines, and another for 6's.

And to answer the question about "euro" value, yes, one euro is very nearly (at current exchange rates) equal to one U.S. dollar.

Getrag 240

Thanks Otto. I had posted the link to your page in an earlier reply, but there was still some controversy about some of the differences between the 240 and 265.

Do you happen to know if a GM corporate "standard" yoke will work in place of the auto yoke on the 240? Do you happen to know the input and output spline type on the 265?

Does the 265 have the separate bellhousing and the 240 the integral bellhousing, such as the two pictures above?

The shifter in the 265 seems quite different than the 240 (assuming I have the correct number for the pictures above). Can it be modified to fit a GT? Should anyone even attempt to use a 265 in a GT (unless there is a reason for extreme power output)?

By the way, I "fixed" the link that you had posted in your first reply. For some reason, the program added some characters to the string.

Thanks again for your help.

Getrag 240 and 265

Side view of Tom's Getrag 240 (with bellhousing) and 265 (without bellhousing). It looks like the 265 tail piece is quite a bit longer, with an additional piece in the middle.

Getrag 240 and 265

Front view of Tom's Getrag 240 (with bellhousing) and 265 (without bellhousing). It looks like the 265 input shaft has fewer splines. Tom, what are the respective spline counts, and what is the O.D.?
