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

Also check for:

- Check the ATF level and check the ATF cooler lines for leakage and loose connections. If necessary, clean the ATF cooler lines.
- Check for a loose shift cable at the shift lever and the transmission control lever.
- Check the line pressure.
- Check the ATF strainer for debris. If the strainer is clogged, find the damaged components that caused the debris.
- Improper alignment of the ATF pump and the torque converter housing may cause ATF pump seizure. The symptom is mostly an rpm-related ticking noise or a high pitched squeak.
