Has anyone put a Commodore auto into their Falcon before?
3rd and 4th are the same, but 1st and 2nd are far lower, even a bit lower than a T5, and if theyre swappable, I could have one at no cost. Theyre the same transmission but I assume rigging it into the falcon ECU could be tricky..?

Might be able to get a 4l60 working, doubt you'd be able to get a 4L60-E going though.
You'd also need custom bellhousing and crossmember.

Basically, a lot of effort. Sell it and buy either a T5 or a shorter diff ratio!

all im thinking is why! even if u do have one for free.

Fair enough, ide much prefer a T5 anyway, im just looking for cheap options at the moment as im a poor student.

something wrong with ur tranny?
bit more mucking around putting a manual in
