## Honda Multi Matic Transmission/CVT

#### Symptom Troubleshooting Index (cont'd)

14-243

Symptom | Probable cause(s) | Notes
No shift to higher ratio or lower ratio |

1. Intermediate housing assembly worn or damaged
2. Pulley pressure feed pipe damaged or out of round
3. ATF pump worn, binding, or foreign material in ATF pump
4. Low ATF level
5. ATF strainer or ATF filter clogged
6. Valve body assembly defective
7. CVT pulley pressure control valve assembly defective
8. CVT speed change control valve assembly defective
9. Solenoid harness worn or damaged
10. Drive and driven pulley speed sensors defective
11. CVT speed sensor or vehicle speed sensor defective
12. PCM defective

- Check the drive and driven pulley pressure and lubrication pressure. Measurement of the pressure is low or no pressure, check the ATF pump, chain and sprocket.
- Inspect the differential pinion shaft for wear under the pinion gears. If the differential pinion shaft is worn, overhaul the differential assembly, replace the ATF strainer, thoroughly clean the transmission and flush the torque converter, cooler and lines.
- Check ATF level and check ATF cooler lines for leakage and loose connections. If necessary, flush ATF cooler lines.
- If the strainer is clogged, find the damaged components that caused debris.
- Check the indicator light indication and check for loose solenoid harness connector.
