I would like to put a 66RFE Transmission behind my Mopar B/B 440 RB in a similar fashion to the A518 shown in the post "Big block a518 overdrive conversion (lots of pics)" posted on this forum some time ago.

See: https://board.moparts.org/ubbthreads/ubbthreads.php/topics/35994/1.html

I have been in touch with JW and they are not sure if it is possible using their Ultra-Bell #92457 "Big Block Chrysler to TF727 or A518".

My question is ….is the bolt pattern/size of the A518 pump the same as the 66RFE pump?

Can I cut off the 66RFE's bellhousing and use JW part#92457 as if it was an A518?

The plan is to then use a PCS 2800 to control it.

There is no likeness between the 518 and RFE pumps.

Only way I can see you using the RFE family would be to use an adapter or cut the bell off and weld a 727 bell on.

You need a stand alone controller to run any RFE trans - they are completely electronically controlled.

Thanks Transman according to transmissiontuner.com the PCS TCM-2800 with a "helper Module" of his own design can be used to control the 66RFE http://www.transmissiontuner.com/68RFE-Swap.html

Did you read the whole article? there is a lot involved in that set up.

Thanks Transman

Do the pump bolts share a common PCD?

Would you happen to have a photo of the two pumps to help me appreciate the differences?

Thanks stumpy

Yes I have read the entire article …. its not a Sunday afternoon job.

Transman do you know if the A518 & the 66RFE share the same bellhousing bolt pattern?

It’s my understanding that 318/340/360/5.7/6.1/6.4/6.7 share the same bellhousing bolt pattern.

Been over two years since I left Chrysler and if memory serves me that was a fact back then.

Now, the 518 has a cast iron pump held in the bell.
All RFE has a “hub cap” that covers the internal pump and is held in place with a snap ring.

Look inside a RFE bell and all you will see is that hub cap.
The pump is an aluminum body bolted to the case behind that cover.

Here are pics

You might be able to use a JVX adapter to bolt the trans to the engine. Getting the converter connected to the crank might take some creative machine work but should be doable I would think.
