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. Transmission-to-engine assembly error

10. Axle disengaged

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 selector control lever.
- Check the line pressure. A/T Pressure Test
- Improper alignment of the ATF pump and the torque converter housing may cause ATF pump seizure. The symptoms 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 cause ATF pump seizure.
- Install the main seal flush with the torque converter housing when replacing the main seal. If you push it into the torque converter housing until it bottoms out, it will block the fluid return passage and result in damage.
- 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 ATF cooler and the cooler lines.
- Replace the torque converter.
- Inspect the countershaft and the secondary shaft for wear and damage.
