i'm not asking you to find a trans, im asking you to find proof that one existed.

having worked at a GM dealer, i had access to both parts documentation, and service data. i too searched for information on the 4L80E to swap into a project i was working on at the time, and saw no mention of anything but a 4L80E. no such animal ever existed. if it were in fact an actual trans, someone would have reproduced the non-electric valve body for use in an 80E for conversion purposes. to date, the only non-electric valve body available for an 80E is a full manual valve body, with no ability to shift anything on its own.

i dont want to see a trans, i want to see some form of concrete information confirming its existance, from a reputable source.
