    Hey y’all, I’ve been on quite the journey with my 2013 Tundra this year and could use some advice. A few months ago, my 4LO started blinking, and the check engine light came on. I took it to AAMCO, and they recommended replacing the entire valve body. I declined since my diagnostic report pointed to speed sensor issues instead.

    After replacing the speed sensors, the truck started shifting rough when switching into drive and reverse. The check engine light and 4LO indicator kept flashing. More recently, I took it for an emissions test, and a new code popped up—P0705: Transmission Range Sensor "A" Circuit (PRNDL).

    My question is: Should I continue replacing sensors, or could this be a deeper wiring issue, a blown fuse, or something else? I’ve checked some fuses (they seemed fine) and also noticed a loose wire harness, though I’m not sure what it connects to.

    Any insight would be much appreciated! Thanks in advance.
