aod output shaft-driveshaft yoke spline count?

[70torino429]

Hello, i was wondering what the spline count on the aod output shaft-driveshaft yoke was? is it a 31 spline like im hopeing for?

It's either 27 or 28, I forget.

FYI also...
Some AOD/E's and all the 4R70Ws also have larger diameter output shaft bushings & larger diameter yokes. All models have the same 28 spline output shaft profile, so small bushing tail shaft housings can be swapped on from any model, including from an AOD. This is also the same as C-4 transmissions which makes swaps easy.

Google rocks... makes me think I really should try out a 4r70W tailhousing and yoke just for the larger diameter....

Ok, thanks!

Would be a good and cheap upgrade.

Have you broken the front yoke before?

so, im thinking this will work on a tko transmission even though its made for a c6, but it has the 31 spline count im after.. Im going to need a stronger driveshaft custom made anyways.

I have blown a tailhousing apart.....

How the hell do you do that?

Bent driveshaft. Pretty easy to do. I had a nasty habit of bending driveshafts in the old sedan.

What was the cause of the bent driveshafts? Just so I know what not to do after I have mine made.

Well, I did lots of drag racing, burnouts, drifting, top speed runs.... Take your pick
