I have a 99 spyder with a 4g64 and auto trans. The trans is having some issues and I need to replace it soon. I plan on adding a turbo in the near future so I figured I would go ahead and upgrade while im at it. Will a trans from auto or manual from a 4g63 work? Id prefer to stay auto for better boost but wouldnt mind going with 5 speed if it were and easier swap.


Thanks for the help
