Hello,Definitely shop around; I imagine you'd find something much more cost effective....So fluid flush w/the correct fluid for those units, wiring harness w/temp sensor (one-piece design) and fast adapt relearn for $1,770.00...No reprogramming is needed for simply swapping the harness or even for rebuilding the transmission. The only time you'd need to actually reprogram the unit is if you were swapping in a used trans from another vehicle w/a different TEHCM/TCM part number or replacing your ECM.
Here's a Sonnax article on the relearn process if you're interested to learn a little more about it and how it's done.
I spoke with a different dealer and they came up with a similiar price. I called a independent shop and he said he didn’t believe it’s just the fluid and there are other problems but said he wants to drive it first and doesn’t charge for diagnosing. My coworker has someone he trusts and will get me there name. What are your thoughts?
