545RFE questions...

[Stacked440]

I want to put a 545RFE in my duster but I'm having a hard time finding an answer to mainly one question,  does the 545RFE in 2004+ have its own computer or does it share the 5.7L ECU?  I was told that 2003 had a ECU and a TCM,  and 2004+ use just the ECU for transmission control and engine management, but I've also been told its exactly the other way around?  I trust both sources so I'm trying to take a democratic approach

I will see if I can find out for you.

The 2003 5.7 and tranny I got from a Dodge Ram 4X4 had separate controllers for the tranny and engine.

My main concern besides the computer is the transmissions physical size, I know i need to modify the tunnel but how much and where I have no idea, I can't find dimensions anywhere online, does anyone have general dimensions like Length, width, height, and maybe even girth about midway between bellhousing and end of tailshaft?

I have one at the shop I can measure for you if you like.

I would appreciate that a bunch, trying to get my ducks in a row for the conversion.

Just to get back on this,the core I have is a 4X4 so the length will be different then a 2WD. Do you still want me to measure it?
