Saw your post about the transmission one guy was selling with a 4.428 final drive. It's from a sentra se-r.

Looks like 07 & 08 used the 4.428 final drive. Before that it was 4.133, same as 04-06 maxima's. Exact same transmission with a different bell housing. Also, all the se-r transmissions came with lsd and cost less used than maxima transmissions.
