It heavier, rear mount is about 3." inches farther back, Pan is longer but it is slightly narrower.

In my case the 4L80E has more tunnel clearance than a 4L65E. X-member was easy mod. Only fit issue was mounting tab on bellhousing. That seems to be a common problem. Had more clearance on sides of tunnel than with 4L65E.
