crossmembers the same on swap?
1. Is the auto crossmember the same as the manual crossmember?
2. Will the auto xmember work with the m6?
3. Which would be easier to use when doing a TH400 swap?
2)- Nope
3)- Unknown.
I am in the process of doing the a4 to m6 conversion and I had to get an m6 cross member AND trans mount.
Unsure if I NEEDED the trans mount.. but gm said I would lol. I have a VERY GOOD friend at GM and he suggested I get the trans mount to stay safe.
