Lack of rear lube style output shaft for pre 1987 AODs’. Failure with 3.55,3.73.

[macx]

About the rear lube, they've got the article
set up so you can't clip/copy/save, or anything,
but that info is on page 12.

You have to take the extension housing off which
means supporting the trans, loosening/relocating
the rear trans support, and dropping the tailpipes
down from the headers - not easy, but at least
the trans doesn't have to come out.

Probably not worth it unless you do lots of
hi speed driving with the deep gears.
