The Supra transmission is one from a 88-92 turbo, and the model is the R154. The trans from the non-turbo should also bolt up, but is not as durable as the R154. The Dakota bellhousing was used with the AX15 transmission, and both the R154 and the AX15 are built by Aisin-Warner. The bolt pattern on the transmission is very common, and was used with a variety of vehicles/transmissions. The Solstice/Sky aren't common over here, but the Colorado/Canyon trucks are, as well as the Isuzus I mentioned. I'm not familiar with what European cars may have come with these transmissions (other than the Supra), but there must be quite a few. Here's an article that covers MANY of the possible swap options for this family of transmissions:
