Bad case of Tinkeritis!
It unlocks to shift as a factory one does, but since you can set it to lockup at any speed it works like a lockup switch. This system is similar to how the factory pcm works but completely tunableI think you missed my point. I understand what you've said though. I want to know if its possible to lock up 2nd and 3rd, but it unlock to shift... Locked shifts are not necessary for every day driving, Im not really interested in putting that much stress on the input while towing either. If its not possible, then its not possible. Doesn't make me like the controller any less.
