Hey man.
I don't know for sure but would hazard a guess that the output shaft spline count would be different too.
Do you know if the trans mounts are the same?
What about the length of each trans?
cheers

Re: 904 vs Borgwarner AUTOS
wont throw ur speedo out (assuming ur not changing diff ratios and wheels/tyres)
Yes you can put in a late 80's/early 90's Falcon valve body in the BW(as a bolt-in mod) for a more aggressive shift pattern (acn only be a 3-speed auto from the Falcon)

Re: 904 vs Borgwarner AUTOS
I swapped a BW for a T904 and it did throw my speedo out a fair bit (about 10% but I never had it accurately tested or checked against a GPS so this is a guesstimation only - and this was in a GD wagon with the original auto diff)sigtool wrote: would the borg throw my speedo out?
