Replacement transfer case shift actuator for 4WD Toyota Tacoma, Tundra and 4Runner that fixes a 4WD light that blinks and a truck stuck in 2WD or 4HI.
This is the electric shift actuator that bolts to the side of the transfer case on four-wheel-drive Toyota trucks and moves the shift fork when you turn the 4WD selector. It replaces Toyota part number 36410-34015 and the earlier 36410-34010 through 36410-34014 service numbers, plus aftermarket 141557. It fits 4WD models only.
Fitment: 2005-2015 Tacoma 2.7L four-cylinder and 4.0L V6, 2016 Tacoma 3.5L V6, 2000-2004 Tundra 3.4L V6, 2005-2006 Tundra 4.0L V6, 2000-2006 Tundra 4.7L V8, and 2014-2019 4Runner 4.0L V6. Match the part number on your old unit before ordering.
The symptoms that point to this actuator are familiar: the 4WD or 4LO indicator flashes and never goes solid, the truck will not come out of 4HI, or it refuses to engage 4WD at all while the transfer case itself shifts fine by hand. Water intrusion and worn internal gears or contacts in the motor are the usual causes on high-mileage trucks. Before replacing it, check the actuator fuse and connector for corrosion and scan for 4WD codes so you are not chasing a switch or wiring fault.
On the bench: put the transfer case in 2WD with the engine off, unplug the connector, remove the mounting bolts and slide the old actuator out of the case. Clean the mating surface, install the new unit with a fresh seal or a thin bead of sealant where the original had one, torque the bolts evenly, reconnect the harness and cycle through 2WD, 4HI and 4LO with the truck rolling slowly to confirm the indicator goes solid in each range.
