Automatic Transmission - will this transmission work for my friend?

friend of mine is in need of a transmission for his 1984 camaro V6 auto

i see theres one here on the boards from a 1986, but would it work for his 84??

i heard pre 85' the splines were 27 and 85+ they were 31
as long as the torque converter comes with the tranny, it should work right?

will it still bolt up to the engine?

Thanks!!

Ron

yes it if comes w/ the tq convertor the flywheels are the same bolt pattern to a 700r4
