4L60E transmission output shaft specifications

[dhrivnak]

By any chance does anyone know the dimensions or have access to a drawing of the output shaft for the transmission on the 1500 Avalanche?? I am working on a major modification and need the specifications on the spline shaft of the transmission.? I can not find those details in the shop manual nor have I had any luck in 3 days of searching on the web.? I need to buy a coupler and the manufactures want the exact dimensions on the splines, their angles and depth.?

I can reverse engineer but I would rather have the engineering dimension's rather than my micrometer measurements.? Thank you

BTW, anytime you pick up a performance magazine and look at a Project car or truck, you can almost bet Chuck has built the tranny.....

I thank you and found them but was not 100% sure they were the same.  I now know, thank you.
