2008 Astra XR
Default A Six Speed?

Hello everyone. I'm wondering at the probability of a new transmission. I know that it would require a LOT of things, but bare with me. My thinking is that, in a perfect world, you might be able to get away with putting the 6T40 transmission from the Chevrolet Sonic into an Astra since both cars use the 1.8l transverse Ecotec engine. The Sonic is a smaller car, so it's transmission should fit? I'd love to hear any thoughts on this.
