ON-VEHICLE SERVICE
23100090374
ESSENTIAL SERVICE AUTOMATIC TRANSMISSION FLUID CHECK Caution When the transmission has been replaced or overhauled, or driving has been carried out under the severe condition, the transmission fluid cooler line flushing should always be carried out and also, the transmission fluid and oil filters (special filters for transmission only) should always be replaced. 1. Drive the vehicle until the fluid temperature rises to the normal temperature (70 - 80_C). 2. Park the vehicle on a level surface. 3. Move the selector lever through all positions to fill the torque converter and the hydraulic circuits with fluid, and then move the selector lever to the N position. 4. After wiping off any dirt around the oil level gauge, remove the oil level gauge and check the condition of the fluid. NOTE If the fluid smells as if it is burning, it means that the fluid has been contaminated by the particles from the bushes and friction materials, a transmission overhaul and flushing the cooler line may be necessary. 5. Check that the fluid level is at the HOT mark on the oil level gauge. If the fluid level is lower than this, pour in more fluid until the level reaches the HOT mark. Automatic transmission fluid: Dia Queen ATF SP II, ATF SP II M or equivalent NOTE If the fluid level is low, the oil pump will draw in air along with the fluid, which will cause bubbles to form inside the hydraulic circuit. This will in turn cause the hydraulic pressure to drop, which will result in late shifting and slipping of the clutches and brakes. If there is too much fluid, the gears can churn it up into foam and cause the same conditions that can occur with low fluid levels. In either case, air bubbles can cause overheating and oxidation of the fluid which can interfere with normal valve, clutch, and brake operation. Foaming can also result in fluid escaping from the transmission vent, in which case it may be mistaken for a leak. 6. Securely insert the oil level gauge.

AUTOMATIC TRANSMISSION FLUID REPLACEMENT 23100100411
Caution When the transmission has been replaced or overhauled, the transmission fluid cooler line flushing should always be carried out before installing the transmission fluid cooler hose. If you have a fluid changer, use this changer to replace the fluid. If you do not have a fluid changer, replace the fluid by the following procedure. 1. Disconnect the hose shown in the illustration which connects the transmission and the oil cooler (inside the radiator). 2. Start the engine and let the fluid drain out. Running conditions: N range with engine idling Caution The engine should be stopped within one minute after it is started. If the fluid has all drained out before then, the engine should be stopped at that point. Discharge volume: Approx. 3.5 L 3. Remove the drain plug from the bottom of the transmission case to drain the fluid. Discharge volume: Approx. 2.0 L 4. Replace the oil filters. (Refer to P.23-47.) 5. Install the drain plug via a new gasket, and tighten it to the specified torque. Tightening torque: 32 Nm 6. Pour the new fluid in through the oil filler tube. Adding volume: Approx. 5.5 L Caution Stop pouring if the full volume of fluid cannot be poured in. 7. Repeat the procedure in step 2. NOTE Drain the fluid from the cooler hose 7 lit. at least. Then drain the fluid a little and check the fluid for dirt. If it has been contaminated, repeat the steps 6 and 7. 8. Pour the new fluid in through the oil filler tube. Adding volume: Approx. 3.5 L
23-46
AUTOMATIC TRANSMISSION - On-vehicle Service 9. Reconnect the hose which was disconnected in step 1 above, and firmly replace the oil level gauge. 10. Start the engine and run it at idle for 1 - 2 minutes. 11. Move the selector lever through all positions, and then move it to the N position.
12. Check that the fluid level is at the COLD mark on the oil level gauge. If the level is lower than this, pour in more fluid. 13. Drive the vehicle until the fluid temperature rises to the normal temperature (70 - 80_C), and then check the fluid level again. The fluid level must be at the HOT mark. NOTE The COLD level is for reference only; the HOT level should be regarded as the standard level. 14. Firmly insert the oil level gauge into the oil filler tube.
AUTOMATIC TRANSMISSION FLUID COOLER LINE 23101300070 FLUSHING Caution When the transmission has been replaced or overhauled, or automatic transmission fluid is contaminated, the transmission fluid cooler line flushing should always be carried out. 1. Disconnect the hose shown in the illustration which connects the transmission and the oil cooler (inside the radiator). 2. Start the engine and let the fluid drain out. Caution The engine should be stopped within one minute after it is started. If the fluid has all drained out before then, the engine should be stopped at that point. Discharge volume: Approx. 3.5 L
AUTOMATIC TRANSMISSION - On-vehicle Service
23-47
3. Pour the new fluid in through the oil filler tube. Adding volume: Approx. 3.5 L Caution Stop pouring if the 3.5 lit. of fluid cannot be poured in. 4. Repeat the procedure in step 2.

DRIVE GEAR BACKLASH CHECK Check the drive gear backlash by the following procedure: 1. Place a dial gauge on the drive gear teeth. With the drive pinion locked in place, check if the backlash is within the standard value range at four points or more by turning the drive gear. Standard value: 0.11 - 0.16 mm 2. If the backlash is outside the standard value, adjust using the side bearing spacer. 3. After adjustment, inspect the contact of the drive gear. DRIVE GEAR RUNOUT CHECK Check the drive gear runout by the following procedure: 1. Place a dial gauge on the back of the drive gear, and check if the runout does not exceed the limit by turning the drive gear. Limit: 0.05 mm 2. If the runout exceeds the limit value, check that there is no foreign material between the reverse side of the drive gear and the differential case, or that there is no looseness in the drive gear mounting bolt. 3. If step (2) is normal, change the assembly position of the drive gear and differential case, and then take another measurement. If adjustment is impossible, replace the differential case or the drive gear and drive pinion as a set.

DIFFERENTIAL GEAR BACKLASH CHECK Check the differential gear backlash by the following procedure: 1. Lock a piece of wood between the side gear and the pinion shaft to hold one of the side gears in place. Then place a dial gauge (through a suitable extension) on one of the pinion gears, and check if the backlash is within the standard value range. Repeat this check for the other pinion gear. Standard value: 0 - 0.076 mm Limit: 0.2 mm 2. If the differential gear backlash exceeds the limit, adjust the backlash by installing thicker side gear spacers. If adjustment is impossible, replase the side gear and pinion gear as a set.
DRIVE GEAR TOOTH CONTACT CHECK Check the drive gear tooth contact by the following procedure: 1. Apply a thin, uniform coat of machine blue to both surfaces of the drive gear teeth. 2. Insert a special tool between the differential carrier and the differential case, and then rotate the companion flange by hand (once in the normal direction, and then once in the reverse direction) while applying a load to the drive gear, so that the revolution torque [approximately 2.5 - 3.0 Nm] is applied to the drive pinion.
