Thanks for the explanation. At this point, the tranny now has a rear reluctor and I assume will shift correctly regardless of the t-case positioning, correct? I have converted to a dual stick with the modified rails so I really want this to work correct. I don’t see how the incorrect vss would mess up the tranny either, unless the computer was telling it to shift hard or incorrectly. It would shift into 2nd at about 10-20 mph, hold 3rd until 60 or so, then eventually shift into OD. That was one area I had attributed to settings that maybe was actually a result of this whole issue? At fwy speed it would hold 3rd for a long time unless I let off the pedal, then it would shift into OD and stay there. But that only happened upon merging onto the fwy, after that it would engage the TC or downshift appropriately. Or at least I THOUGH appropriately.
