D.Hearne, all C5's start with E2. They came in case or pan fills. The bellhousings are deeper to make room for the thicker lockup TC. I have heard of some that do not have lockup TC that use E2 cases, but that would be a C4. The only thing that makes a C5 is the VB, input shaft, lock TC and bell housing. E2 cases have better oiling, but everthing interchanges with a C4..
Whatever. You can keep on believing only the 80's C5 was the only one, that's you choice, but the fact still remains that the 70's pan fill transmission was also considered a C5 by Ford and many others.
