AUTOMATIC TRANSMISSION FLUID (ATF) K AUTOMATIC TRANSMISSION FLUID (ATF) ATF Inspection Level 1. Park the vehicle on level ground. 2. Apply the parking brake and position wheel chocks se- curely to prevent the vehicle from rolling. 3. Warm up the engine until the ATF reaches 60-70°C (1 40-1 58°F). 4. While depressing the brake pedal, shift the selector lever to each range (P-L), pausing momentarily in each range. 5. Shift back to P. Note In some cases it may be necessary to inspect the ATF in the cool range 15-25°C (59-77"F) before warm- ing up the engine. 6. Ensure that the ATF level is in the HOT (65°C) range. Add ATF to the specification, if necessary. ATF type: DexronQII or M-I11 Condition Determine whether the transmission should be disas- sembled by noting. 1. If the ATF is muddy or varnished. 2. If the ATF smells strange or unusual. Gartner Banana

TRANSMISSION TRANSMISSION UNIT (DISASSEMBLY) Preparation SST 49 H075 4958 Body (Part of 49 U019 OAOA) For disassembly of transmission For disassembly of transmission For disassembly of transmission 49 U019 OAOA Hanger set, transmission 49 U019 003 Holder (Part of 49 U019 OAOA) For disassembly of transmission For disassembly of transmission Precaution General notes: 1. The oil pan could contain small chips, shavings, and other particles helpful in checking the condition of the transmission and diagnosing certain problems. To ensure that all foreign particles stay in the oil pan, make sure that the transmission is never tipped completely over while the oil pan is still installed. L/ 2. Disassemble transmission in a clean area (dust proof work space) to prevent entry of dust into the mech- anisms. 3. Inspect the individual transmission components in accordance with the QUICK DIAGNOSIS CHART during disassembly. 4. Use only plastic hammers when applying force to separate the light alloy case joints. 5. Never use rags during disassembly; they may leave particles that can clog fluid passages. 6. Several parts resemble one another; organize them so they do not get mixed up. 7. Disassemble the control valve assembly and thoroughly clean it when a clutch or brake band is burned; or when the ATF has degenerated. Cleaning notes: 1. Clean the transmission exterior thoroughly with steam or cleaning solvents, or both, before disassembly. Warning Using compressed air can cause dirt and other particles to fly out, causing injury to the eyes. Wear protective eye wear whenever using compressed air. 2. Clean the removed parts with cleaning solvent, and dry with compressed air. Clean out all holes and passages with compressed air, and check that there are no obstructions. Gartner Banana

K TRANSMISSION LOW AND REVERSE BRAKE Preparation SST Preinspection Low and reverse brake operation 1. Apply compressed air through the oil passage as shown. 49 0378 346 Hex head wrench Air pressure: 392 kPa (4.0 kglcm2, 57 psi) max. For removal I installation of one-way clutch 2. Verify that the retaining plate moves toward the snap ring. If not, the seal ring or O-ring may be damaged or fluid may be leaking at the piston check ball. Inspect them, and replace as necessary when assembling. Clearance between retaining plate and snap ring 1. Measure the clearance between the retaining plate and the snap ring. Clearance: 0.8-1.05mm (0.032--0.041 in) i/ 2. Select and install the correct retaining plate when as- sembling. Gartner Banana
