Engine Runs, But Vehicle Does Not Move In Any Gear

Engine runs, but vehicle does not move in any gear

Diagnostic Procedure:

1. Low ATF level

2. Shift cable broken or out of adjustment

3. Connection between shift cable and transmission or body is worn

4. ATF pump worn or binding

5. Regulator valve stuck or spring worn

6. ATF strainer clogged

7. Mainshaft worn or damaged

8. Final gears worn or damaged

9. Park mechanism defective

10. Transmission-to-engine assembly error

11. Axle disengaged

Also check for:

- Check the ATF level and check the ATF cooler lines for leaks 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.
- Improper alignment of the ATF pump and the torque converter housing may cause the ATF pump seizure. The symptoms are mostly an rpm-related ticking noise or a high pitched squeak.
- Check the line pressure.
- Check the ATF strainer for debris. If the strainer is clogged, find the damaged components that caused the debris.
- Inspect the differential pinion gears for wear. If the differential pinion gears are worn, replace the differential assembly, replace the ATF strainer, thoroughly clean the transmission, and clean the cooler and lines. Replace the torque converter.
- 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.
- Install the main seal flush with the torque converter housing. If you push it into the torque converter housing until it bottoms out, it will block the fluid return passage and result in damage.
