The automatic in the gt is a GM part that was used on some of their larger engines. It is very sturdy and could take the abuse of a 2.4L motor. I have had 3 Automatic gt's and other than a leakey oil line the automatic's never had any problems.

I also have a question on this subject. Was the automatic fitted at the plant in euorpe, or was it dealer installed, I have heard conflicting stories, I know that the ac was dealer installed but if the auto trans was then wouldent there have been a bunch of brand new manuals laying around the dealers garage?

I have only owned gt's(I would buy a manta but I have never seen one for sale)
The gt auto or manual has the exact same floor pan. The GT's that I have had with automatics had the mount and hole for the cable already there. Also the autos and manuals used different cross members but both had the mounting holes for either one.

>If the floor pans are the same for the manuals and the autos... >Is there a difference in the tranny mount?

*****yes thats what I ment when I said cross meber,
the autos and the manuals have differnt mounts. But the holes to mount either transmission are present in every car.

and I would assume that there is a different console also?

******where there is that round rubber booty in a manual there is a mini plastic shift consol that tels you what gear you are in.

Any other diffs (beside flexplate vs torque converter!)

*****the brake petal is differnt(wider), There is a detent cable to downshift, and I believe the hole to mount that cabe too is present on the manual. There is a mount that holds the detent cable. The autos have a differnt radiator, the auto radiator has an oil cooler built into it. Driveshaft is differnt, and one of the most important differnences that most people forget is that the manual has a needle bearing that fits in the end of the crank shaft, the auto's do not have this and you need to add that if you are converting from auto to manual.

What 3.4L are you talking about? Did you mean 2.4L or am I missing something? I have been out of opels for a while

as far as the transmissions I still think it is better to use the Getrag with opel motors, and if you can hawlk the money get the kit from Gil. I got one for the last gt that I restored and it was bolt on, every piece was included and it worked flawlessly. You can also get a Getrag unmodified from Germany for about $150 plus $hipping.

There are posts in the Yahoo classic oples list as to all of the modifications needed for the T-5

The list I am talking about is at

http://groups.yahoo.com/group/classicopels/

It started with the armory group, then they made the Egroups group, then yahoo bought Egroups so now it is Yahoogroups.......anyway it is basicly like this group only you get all of the messages in either digest or individual form in your email. Or you can read them directly off the site, but the interface is not nearly as good as Gary has set up here and it can be tricky to find past articles.
I like this forum way better than the yahoo one, but they have mamy more members, I hope people start switching over.
