neutral safety switch?????

Ok so I posted a while back about my 2014 Trd pro. On occation Ill be cruising along and the truck will spontanously drop a few gears and of course the tach jumps up in that moment. It corrects itself maybe when the ECU realizes the truck was up to speed. It happens kind of quick. Now I know these trucks are pretty sensative to touching the brake a such, to lower a gear, but this happens when at 40 mph on a straight road. It can even happen as it is accelerating up to 5 or 6th gear. So this may have nothing to do with it, but every time it has done it, it was raining ( ahhh electrical short?). And of course I have the wipers on too ( are there any safety switches connected with wiper switch or just coincidence?)
Another part of the troubleshoot....when in drive the " D" is not elluminated, but in park and sport the P and S do light up.

Neutral safety switch??? and has anyone ever changed one of these themselves?

Any ideas on this???

iirc there was a thread about something similar.i think it turned out to be defective tail light bulbs/contacts or brake switch

switch is right on transmission .remove selector arm and replace.
