drive shaft yoke options for 6l80
Has anyone used a 400 yolk on a 6l80 trans and eliminated the 3 bolt flange and cut off centering stud looks pretty straight forward. Im just wondering what Im missing Thanks Don

I don't know that the splines are the same as a TH400...do you? I am also pretty sure that the output shaft of a 6L80 isn't very deep inside and may not have a bushing to support a conventional yoke. There are adapters that mate to the 3 bolt flange and then you can have a driveshaft built with a slider in the middle or CV joints that have about 1.5" of plunge.

Thanks the splines are the same on the turbo 400 I have a C-3 Corvette yolk that is about 1/4 in. longer than flange but I see what you are saying about support bushing. I guess this is what I was missing Thanks

Don,
What we've done in the past is swap out the output shaft and tailhousing to the slip yoke style that was used on some vehicles. It's not that hard to do on that transmission. Then you can use any 32 spline slip yoke style driveshaft.
