Hey does anyone know if there is a difference in the tailshaft lengths on the 4L80E between a 2wd and a 4wd. I know that there is a difference in the 4L60/700R4 but was not for sure about its big brother. I have a 2wd tranmission and want to use it in a 4wd application. I did not want to waste time on it if it would not work. Thanks for any responses.

I believe there is a difference between the 2wd and 4wd tranny output shaft lengths. Easy to swap them out during an overhaul.
