How does this tie in to the mechanical end of the valve body.

Same way the 440 timers it replaces.. the output connector "notch" to the Camshaft. Timer Assembly it's self slides "down" and held by the "top plate" brackets and timer retaining pin. Recommend you go to Softenerparts website for diagrams and Videos ( or on You Tube channel ). Search 460TC Replacement Timer Assembly for 440 series 4001085

I have a 440i that uses calcite for reducing acid water conditions. Will this control work? are any modifications needed to make it work?

That. I could not answer for you. Im sorry. This was a direct plug and play replacement. And is working great

Does this come with an indoor or outdoor transformer?

It comes with an indoor transformer ( PN 1000811 newest PN 44149 ). Outdoor transformers are more expensive. We offer the options of No Transformer, Indoor, or Outdoor at our Store. Amazon is not set up for selecting options for this Timer.

I Have Soft Water Again!

This unit fit perfectly on my older Autotrol softener and is working great so far and is fairly easy to program. Much cheaper than buying a new softener. I will update this review later if anything changes.

So far so good

So far so good, instead of buying the parts to rebuild my old Autotrol 440 series mechanical timer I decided to upgrade to this electronic timer, no more worry of having to reset the timer after a power outage is a definite plus.
