Will a 1996 ciera transmission bolt into a 1995 Grand Prix?

Any expert info on the 3100 V6 would be great.

hi i just installed a 2000 chevy malibu 3100 in my 95 ciera . i had to change the upper and lower intake manifolds and all the sensors. took me a day and a half but then again i'm 60 yrs old . should'nt be any major problems.
