-4. Use a torque wrench (C) and the socket (D) to rotate the detent shaft, and check that the detent shaft moves smoothly.

Move it back and forth between the P position (E) and the P released position (F) several times.
- Operation angle: approx. 21 deg.
- Operation torque: approx. 4.0 N.m (0.41 kgf/m, 3.0 lbf.ft)
-5. Check that the wheels are locked when putting the detent shaft in the P position. Additionally, check that the wheels rotate when putting the detent shaft in the P released position.

Is the transmission park mechanism OK?
