The first step to install the 1GR-FE engine's rear engine mounting requires starting by supporting the automatic transmission assembly with a transmission jack for slight lifting off the crossmember. The transmission must receive the rear No. 1 engine mounting insulator fitted with 4 bolts that require a torque of 40 Nm (408 kgf-cm, 30 ft-lbf). The engine rear mounting insulator should receive the No. 3 frame crossmember sub-assembly through 4 bolts while maintaining a torque at 16 Nm (63 kgf-cm, 12 ft-lbf). Screw 4 bolts and apply 4 plate washers and 4 nuts on the frame crossmember at the specified torque of 110 Nm (1122 kgf-cm, 81 ft-lbf).
