Adapter 4R70W to BBF 460

Post  jrocco on November 13th 2011, 10:10 am

I am researching adapters to bolt a 4R70W to a 460. So far I have found:

Bendten's - $795.00 http://www.transmissionadapters.com/Ford%20429-460.htm

JW UltraBell - $385.00 - Requires machining off transmission bell
http://www.summitracing.com/parts/JPT-92454-AOD/

Lentec 6A369-ADP-429 - $495.00 http://www.lentechautomatics.com/aodpricing.html

Recommendations?
Are there any others?

I think I would use the jw for the quality and price. You just cut the factory bell off with a cheap saw and bolt the new one to the pump. No expensive machining needed.

just courious, if you are going to use an adapter then why not use a much better 4L80 transmission?

That transmission is about the same size as a BBF. Heavier also.

I'm pretty sure that Lentech adaptor is just a rebranded JW - meaning it's the exact same piece for $100 more. But, from what I've seen/heard this is the way to go.

I have one on an AOD for BBF and it seems to fit well.

Thanks for the photos. That helps alot. Did you cut off the bell or have someone do it?

Also what size converter can you get in that bell?

One other option:

You can get an adapter ring. You cut the bellhousing off and use the ring that allows you to use a stock Ford fmx bellhousing. The fmx bellhousing is bolt on of course. Likely oem apps were mid 70's cars with a 351M/400 .

As for the 4L80, they are big and heavy but imho if you need to buy an adapter and controller then why not use the strongest tranny available?

That's interesting looking, David. Must be a new product. I know Broader does good work.



jrocco, I believe a C6 convertor must be used, but don't quote me on that.

I had to have the bellhousing milled off, didn't do it myself.

Talk to SilverFox Racing Transmissions, also, he's very good and reasonably priced with AOD's. http://www.silverfoxtrans.com/silverfoxtrans.com/Home.html

Also check out .www.clickclickracing.com for good technical support on AOD's. (Silver Fox's forum site).

AOD transmissions require no electronic controls. AOD-E/4R70W trannies, do

I called JW and asked for a copy of the instructions for cutting off the bell. They did not really want to discuss with me. Said the instructions would be shipped with the adapter, but it would be best to talk with FB Performance Transmissions because they had purched some. Thought this was kind of odd.

I decided to go with a manual valve body for this transmission. No electronic controls required this way.

Well I got really confused this morning.
Eric from JW said their Bell adapter only works with AOD's not AOD-E or 4R70W.
He said his understanding was that the AOD-E and 4R70W were completely different from the AOD.

I'm pretty sure that's correct.

Please call Dan at Silverfox or visit www.clickclickracing.com They have some awesome tech on these trannies there.
