REMOVAL & INSTALLATION > TRANSMISSION > REMOVAL & INSTALLATION (GS300 & SC300)

1. Disconnect negative battery cable. Remove dipstick and oil filler tube. Remove air cleaner, mass airflow meter and intake air connector pipe assembly. Remove 8 nuts, 2 gaskets and exhaust manifold with catalytic converter from engine. Raise and support vehicle.
2. Remove engine undercover. On GS300, remove oxygen sensor. Remove 2 bolts and front floor center brace, located in front of transmission oil pan. On all models, remove 3 bolts, nuts and 2 gaskets from exhaust pipes. Remove 2 bolts and exhaust pipe support bracket. Remove 4 bolts and 2 gaskets at tail pipes.
3. Remove front and center exhaust pipes. On GS300, remove 10 bolts and 2 heat insulators. On SC300, remove 4 nuts and heat insulator. Remove 2 bolts and rear center floor crossmember brace located at rear of transmission oil pan. On all models, place reference marks on drive shaft flange(s) for installation reference. Unbolt and remove drive shaft with center support bearing. Plug transmission at tail shaft to prevent ATF leakage (if necessary).
4. Disconnect shift control rod from shift lever. Loosen 2 oil cooler pipe union nuts at transmission. Disconnect 3 clamp set bolts. Disconnect and remove oil cooler pipes. Remove hole cover to gain access to torque converter bolts. Remove torque converter bolts. Using appropriate transmission jack, support transmission.
5. Remove engine rear mounting bolts. Tilt rear of transmission down. Ensure radiator fan does not come in contact with fan shroud. Disconnect vehicle speed sensor connector. Disconnect O/D direct clutch speed sensor connector. Disconnect solenoid connector. Disconnect park/neutral position switch connector. Unbolt all wiring harness clamp bolts.
6. Disconnect electrical connections at starter. Remove 2 starter bolts and starter. Remove transmission-to-engine mounting bolts and ground cable (if equipped). Move transmission rearward, and lower from vehicle.
7. Before installation, measure torque converter mounting depth. See Figure. Measure distance between torque converter mounting surface and transmission case front surface. See TORQUE CONVERTER MOUNTING DEPTH table. If distance is less than specified, reposition torque converter until fully seated. On GS300, install Black torque converter bolt first, and then install remaining bolts.
8. To complete installation, reverse removal procedure. Tighten all nuts and bolts to specification. See TORQUE SPECIFICATIONS. Install NEW "O" ring on oil filler tube. Install NEW exhaust manifold gaskets, exhaust gaskets and exhaust pipe nuts. Refill all fluids to proper levels. Road test vehicle.
