Can a 1996 transmission be used in a 1995 Aurora. It appears the left axle is different. Any mechanical mating issues or PCM issues?
Thanks, jim

As far as I know 95 to 99 Aurora's all got the 4T80E. I know that there were some updates inside the transmission but the bolt pattern did not change. The Autobahn version got different gearing.

Be careful in your transmission swap.
I learned the hard way, about the different gearings.

If you put a different ratio in your shift points will be off in your computer and it wont shift but bang into gear. You will think maybe your motor mounts are bad.

Someone mentioned that you can by a prom maybe from Rock Auto, that can be pluged into the computer that matches the transmission. Or better yet get the prom from the car you pulled the trans from.

Yes the bolt patterns are the same.

Good Luck.
