yes and no .the early 700 and and all 2004rs are ,but the late 700 is not .the early 700 and 200 are 27 spline and the late 7oo is a 30 spline.if you install a late 700 on a 2004r input shaft the vehicle wont move .
thanks Chris. I asked the question because a relative of mine just picked up a firebird with 700R4 and wants to put another converter in. I have a few around from my Buick 200R4 changes through the years but I wasn't sure if they would work for him. I think his 700 is original and would be an early version. we'll verify the splines before trying anything. I appreciate your help - he may contact you to check on new converter prices too.
