    Can a 4L80 be put in a 85 GMC Jimmy, and some how work some how with out the "electronics" on it? I know this is sorta dumb sounding. But i was looking on Jaspers website, and when I put in the year of my truck which is an 85 by the way, the engine and others info, it say a 4L80.. Anyone have reason or is it just the same old catalog errors?

    4L80e came out in 91 I believe. It's always been electronic. I've been told you can buy a programmable brainbox from GM for $750.

    the later models of the turbo 400 were called a 4L80, when they added the electronic controls they made it the 4L80E.

    Actually they were 3L80's before 4L80E's /forums/images/icons/smile.gif

    Same designation style as the 700/4L60E..first 700, then 4L60, then 4L60E. (TH400, 3L80, 4L80E when they finally added OD and Electronic controls)

    4=forward speeds, L=Longitudally (no idea how to write that word) mounted, 60/80 is the series, obviously related to strength, at least in those two cases, and E=Electronic.
