Warnings:
- Since the automatic transmission is made up of precision-manufactured parts, these parts must be handled with great care during disassembly and reassembly to avoid damage or scratches. A rubber mat must be placed on the workbench, which must be kept clean at all times. During disassembly, do not use cloth gloves and rags. If necessary, use nylon products or paper napkins.
- Metal parts can be cleaned using common detergents followed by thorough air drying.
- The clutch disc, plastic pressure plate and rubber parts should be cleaned with automatic transmission fluid, being careful not to leave dust, dirt, etc. on them.
- If the transmission assembly as a whole is damaged, disassemble and clean the cooling system.
1. Remove sand, dirt, etc. from the surface of the transmission assembly.
2. Place the transmission assembly on the workbench with the oil sump facing down.
3. Remove the torque converter.
4. Measuring the input shaft end play before disassembly will usually determine if the thrust washer needs to be replaced (except when major parts are replaced).
- Standard value - 0.3-1.0 mm
Thrust washers are located between the shaft support and the front coupling holder. Install the hour indicator on the torque converter housing.
Make sure that the indicator probe rests against the end of the input shaft.
When checking the end play of the input shaft, move it back and forth using pliers. Do not scratch the input shaft when doing this. Record the indicator reading for use when reassembling the transmission assembly.
5. Summit pulse generators A and B.
6. Remove the manual control lever, then remove the transmission switch.
7. Remove the circlip and servo switch.
8. Remove 6 bolts using the special tool (09452-21100), and remove the oil pump assembly.
Note:
- When removing the oil pump assembly, observe the following procedure to prevent damage to the transmission.
- 1. Simultaneously and evenly turn both handles of the special tool, without tilting, into the "IN".
- 2. When unscrewing with a special tool from the side "A" oil pump, if necessary, can be easily obtained with a rubber or plastic hammer.
