My search for a shorty D100 is over

So, how does the transmission "feel" now? Did it feel the same right up to the point it lost engagement before, or does it even feel more crisp this time?

Great to hear it worked on a long drive.
It feels like a completely stock 46re transmission to me. With a little bit of converter. The controller I am using has 3 modes of operation; normal, sport, tow/haul. I have only been using (and have tuned) the normal mode so far. The first time I put the trans in, it felt similar but it’s hard to correlate because the controller wasn’t tuned at all.
Moving forward, I’d like it to shift a little more firm and I’d like to extend the 2-3 shift a few hundred rpm under cruising. I think both of those are possible in the settings. I’ve done no WOT runs yet.
