14-13

Symptom | Probable cause(s) | Notes
Poor acceleration; flares on starting off in and positions: Stall speed high in , , and positions |

1. Low ATF level
2. Shift cable broken or out of adjustment
3. ATF pump worn or binding
4. Regulator valve stuck or spring worn
5. ATF strainer clogged
6. Torque converter check valve defective

- Check ATF level and check ATF cooler lines for leakage and loose connections. If necessary, flush ATF cooler lines.
- Check for a loose shift cable on the shift lever and the transmission control shaft.
- Improper alignment of ATF pump and torque converter housing may cause ATF pump seizure. The symptom are mostly an rpm-related ticking noise or a high pitched squeak.
- Be careful not to damage the torque converter housing when replacing the main ball bearing. You may also damage the ATF pump when you torque down the main valve body. This will result in ATF pump seizure if not detected. Use the proper tools.
