heres the story.
i have a 1990 automatic 300zx so i needed a new transmission. well i received the new transmission but it was out of a 93 automatic. This transmission is a little bigger than the one the it is already in my 1990. since the production date on my car is august of 1989 is it possible that i need a 1989 300zx automatic transmission to fit my 1990. please any responses would be greatly appreciated. i dont want to keep havin to send transmissions back. Thank you in advance.

You shouldn't have a problem with trans size... the only thing different on a Coupe and a 2+2 is the driveshaft... I'm stumped on this one!
