K MECHANICAL SYSTEM TEST LINE PRESSURE TEST This test measures line pressures for checking the hydraulic components and inspecting for oil leakage. Preparation d 1. Perform the preparation procedure shown in the STALL TEST. (Refer to page K-22.) 2. Connect a tachometer to the engine. Warning Removing the square-head plug when the ATF is hot is dangerous. Hot ATF can come out of the opening and badly burn. Before removing the square-head plug, allow the ATF to cool. 3. Connect the SST to the line pressure inspection hole(s). Procedure 1. Start the engine and check the idle speed in P range. (Refer to section F.) Idle speed: 750--850 rpm * 2. Shift the selector lever to D range and read the line pressure at idle. Caution If the accelerator pedal is pressed for longer than 5 seconds while the brake pedal is pressed, the transmission could be damaged. Therefore, do steps 3 and 4 within 5 seconds of each oth- er. 3. Depress the brake pedal firmly with the left foot and gradually depress the accelerator pedal with the right foot. 4. Read the line pressure as soon as the engine speed becomes constant, then release the accelerator .- pedal. 5. Shift the selector to N and let the engine idle for 1 minute or more to cool the ATF. 6. Read the line pressure at idle and at the engine stall speed for each range in the same manner. Gartner Banana

AUTOMATIC TRANSMISSION FLUID (ATF) K REPLACEMENT 1. On level ground, jack up the vehicle and support it evenly on safety stands. Warning When the transmission and the ATF are hot, they can cause burns to the skin. Allow the transmis- sion and the ATF to cool before doing this proce- dure. 2. Loosen the oil pan installation bolts, and drain the ATF into a container. 3. Remove the oil pan and gasket. 4. Clean the oil pan and the magnet. 5. Install the oil pan along with a new gasket. Tightening torque: 5.9-7.8 N-m (60-80 kgfecm, 53-69 in-lbf) 6. Add approximately 4.0 L (4.2 US qt, 3.5 Imp qt} ATF, and check the ATF level. (Refer to page K-35.) Specified ATF: DexronmII or M-I11 Gartner Banana

TRANSMISSION TRANSMISSION UNIT (REMOVAL) Preparation SST 49 0259 440 Holder, mainshaft For prevention of oil leakage 1. Shift the selector lever to N range. 2. Disconnect the negative battery cable. 3. On level ground, jack up the vehicle and support it evenly on safety stands. 4. 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. Warning When the transmission and the ATF are hot, they can cause burns to the skin. Allow the trans- mission and the ATF to cool before doing this procedure. 5. Drain the ATF into a suitable container. 6. Remove in the order shown in the figure, referring to Removal Note. 7. After removal, remove the oil pan to check condition of the transmission.

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 CONTROL VALVE BODY Disassembly / Inspection Caution 4 Denting or scratching these components will reduce the ability of the transaxle to shift proper- ly. When handling these components or the valve body that contains them, be careful not to drop or hit them. 1. Disassemble in the order shown in the figure, referring to Disassembly procedure. 2. Neatly arrange the removed parts to avoid confusing similar parts. 3. Inspect all parts and repair or replace as necessary. 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. 4. Clean the removed parts with cleaning solvent, and dry them with compressed air. Clean out all holes and passages with compressed air. I ( APPLY SPECIFIED ATF TO INDIVIDUAL PARTS Gartner Banana

K TRANSMISSION UPPER VALVE BODY Disassembly / Inspection / Assembly Caution d Denting or scratching these precisely machined components will reduce the ability of the transaxle to shift properly. When handling these components or the valve body that contains them, be careful not to drop or hit them. Caution Using a magnet in this procedure could magnetize the valve body inner components, reducing the ability of the transmission to shift properly. Note If a valve does not slide out under its own weight, place the valve body open-side down and tap on the valve body lightly with a plastic hammer. 1. Disassemble in the order shown in the figure, noting the proper reassembly direction of the valves and internal parts. 2. Inspect all parts and repair or replace as necessary. 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 3. Clean all parts and bores with compressed air and apply ATF to them immediately before assembly. 4. Assemble in the reverse order of disassembly, referring to Assembly Procedure.
