C-4 shift linkage

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.
 
:D Seems to me if you were trying to win your case and point of view, that article is the last thing you'd want to introduce as evidence.:rlaugh: I think you just sank your own ship,:hail2: since the older C5 was around and in production longer than the "new" C5.
 
Did you read this part?
64-83 (now designated "C4" by Ford)
Case fill {C4 to C9, D0 to D9, & E1SP)
Pan fill {C5 to C9, D0 to D9}
82-86 (now designated "C5" by Ford)
Case fill {E2AP only)
Pan fill {E2TP only}
It clearly states "now designated". 25 years ago you would have been been right.
 
But one company calls a part one thing and another calls it something else. That doesn't change what the part is. The other day 65fastbackresto was looking for a "Engine Block Plate" for his C4 trans. He tried a search as did I in Mustangs Unlimited's website and came up empty handed. I dug up an old catalog of theirs and looked it right up, turns out they called it a "Bell Housing Spacer Plate" and when I went back and put in the part number, it came right up. Still the same part. You are nitpicking details here. It may be called a C4 some places and C5 else where, but it still is what it is. The facts still point to, two different C-4 variations that were called C5's elsewhere.
