I installed the new TCC sol unit. Couldn’t find any degradation of the wires but when I had my sister step on the brake after we started it to shift the trans through the gears a few times , She kept tell me it was being weird I could hear clicks from the shift lever and when she did that the truck would die down then RPM back up. I went to check it out And got in the Durango there was no light indicated on any of the gears and the OD off light was on. I went to go shift it and it was only shift in a funny way about 1 1/2 inches each way. I turned off. I think I messed up the geometry of the shift selector when I reinstalled it. I’m pretty sure wasn’t a electrical issue because the shifter felt funny and only went to certain Distance each way
