(d) Install the temperature sensor to the transmission valve body assembly with the bolt and temperature sensor clamp.

Torque:

10.8 N·m {110 kgf·cm, 8 ft·lbf}

NOTICE:

To prevent it from being pinched between the transmission valve body assembly and the transmission case side cover, pass the transmission revolution sensor (NC) wire under the transmission wire (temperature sensor wire) as shown in the illustration.

*a

(c) Apply adhesive to 2 or 3 threads on the end of the bolt (A) and 2 bolts (D).

Adhesive:

Toyota Genuine Adhesive 1324, Three Bond 1324 or equivalent

NOTICE:

Make sure to install the bolts immediately after applying adhesive to prevent foreign matter from attaching to them.

HINT:

The bolt (A) and 2 bolts (D) are in the locations shown in the following step.

*a

Adhesive

(d) Temporarily install a new transmission case side cover to the automatic transaxle case sub-assembly with the 2 bolts ((A) and (B)).

NOTICE:

  • Bolt (A) is an adhesive-coated bolt.
  • To avoid damaging the gasket, prevent it from contacting the surrounding area during installation procedures.

(e) Temporarily install the 6 bolts (C) and 2 bolts (D).

NOTICE:

Bolt (D) is an adhesive-coated bolt.

(f) Fully tighten the 10 bolts in the order shown in the illustration.

Torque:

Bolt (A) and Bolt (D) :

6.5 N·m {66 kgf·cm, 58 in·lbf}

Bolt (B) and Bolt (C) :

7.0 N·m {71 kgf·cm, 62 in·lbf}

4. INSTALL OIL COOLER UNION SUB-ASSEMBLY

(a) Pass the oil cooler union sub-assembly through 2 new gaskets and temporarily install it to the automatic transaxle case sub-assembly with the oil cooler union bolt.

*1

Oil Cooler Union Bolt

*2

Gasket

(b) Temporarily install the oil cooler union sub-assembly bracket portion to the automatic transaxle case sub-assembly with the bolt.

(c) Fully tighten the oil cooler union bolt.

Torque:

22.6 N·m {230 kgf·cm, 17 ft·lbf}

(d) Fully tighten the bolt.

Torque:

12 N·m {122 kgf·cm, 9 ft·lbf}
