It's back to being an electronic knob now on the 2013+ SR5, the TE still has the shifter though. If I recall correctly, the only 5th gens that had the lever were the SR5 and TE (and now only the TE).
The LE has a similar electric knob as you guys because it also has a similar transfer case differential like you guys I believe (no 2wd mode on the 5th gen LE).
The SR5 and TE have no differential in the transfer case, hence the lever I guess?
