Manuals are cheaper, if you have a core. They also last longer if there taken care of, making cores harder to get.

I got a JY 4R70 trans and added a controller. $700.00 plus fluid. LOVE it......and I've always been a manual guy.

The only downer on the 4r70w I have is that its a 4x4 and I don't have a AODE or 4r70w to rob the output or tail housing. I think I can get those for around 100 dollars total. The trans is supposed to be good but I'd have to pull apart to change output shaft so might as well rebuild and I can't seem to find parts for it like you do for the AOD. I can build a pretty stout AOD for about 1700, steel drum, new bands, new clutches and steels, new 1 piece output shaft, billet servo, one piece input shaft, valve body, and 10' billet convertor (from broader performance). Or can just get standard rebuild and VB for the 4r70w for probably around 1k-1200 plus cost of tail and convertor.

I picked my car up with a toasted AOD, and the auto trans guy in my shop and I (the man is a Ford Senior Master, and a genius) transplanted most of a 4R70W stack into it and left the AOD valve body alone. I've effectively installed the old wide ratio kit and added at least 1 clutch and 1 steel to every clutch pack, and upgraded to steel parts in place of cast iron and uped the OD band to 2 inches. I've been running it for 4 months and I love it. AOD cores are cheap, and if you've already got a 4R70W, I'd go that way. I love mine. With some fill rate mods in the VB, I should be good for 450 HP. Now on to the halfway burnt HO engine...

Thanks for the info, I've seen lots of combo's like the 4r70w put into a AOD. Its going to be my first Overdrive auto rebuild so I'll see how it goes.

For the 4r70w into the AOD swap, you use the input and output shaft of the 4r70w right? Reason I ask that is one of the main weak points of the AOD. I found I can build a completely bullet proof AOD with billet 10" convertor for 1750. Thats upgrading all the cast to steel parts.
