Got the trans in, cross member is just on the studs of the mount since I couldn't find the nuts. Need to align the motor and get the trans down the center of the tunnel but all in all there is no doubt that a 4R70w will fit into a 66 without the need to modify the tunnel.

Motor at the proper angle.

I have had a few "discussions"

about this on here, but by dropping the tranny mount about 1", no tunnel mod is needed for a TKO....

But back on topic, I am sure an AOD can be modified to take 550 HP.

Give Jay a call at Broader Performance for a good price on a wwell built AOD and see about a constant pressure valve body - that way you have no need for the throttle valve cable.

I can see how the cross member could be an issue with an AOD. The AOD is 22 5/16 to the mount while the 4R70W/AODE are 23 5/16. The extra inch gets the cross member far enough back to clear the tunnel support (or whatever that piece might be called that is welded into the tunnel). If I were doing an AOD I would modify my current cross member. But with the 4R70W is fits perfect, tight but perfect.
