A500 in a 1970 A Body

the A500 is the smaler body modern O.D tranny,,,the 518 is the bigger body tranny,,, before u do the A500 look in to the set up for the O.D. see what that takes to hook up,,,i know from dong a 518 and im not sure the A500 is the same,,but,,up to 1992 the O.D is an easier hook up then the 1993 and newer 518,,,al tho its not that big of a deal,,,but a lot of guys that have no clue wil tell you both these trannys are junk,,, if you hook them up correctly they run fine,,

and i agree the keislier O.D auto matic is costly,, and its a GM trany,,,wont find that in my car,,,

Actually thru 95 they are all hydraulic controlled except for the OD switching. 96 is when they went all electronic. I have read the 92's had some issues that were resolved in 93 so a 93-95 is better.

Awhile back I rebuilt an A500 for a buddy and when I had it here I looked it over good to see how well one would fit in my Cuda. It's quite a bit smaller than a A518 so I don't think you'd actually have to modify the tunnel any. Just the crossmember and shorten the driveshaft. But I didn't actually try test fitting it up in there since my car was assembled. Just took measurements. It's close but I think it will clear the tunnel.
