Engine Runs, But Vehicle Does Not Move In Any Gear

Engine runs, but vehicle does not move in any gear

Low ATF level

Shift cable broken or out of adjustment

Connection between the shift cable and transmission or shift lever is worn

ATF pump worn or binding

Torque converter defective

Regulator valve stuck or spring worn

ATF strainer clogged

Mainshaft worn or damaged

Final gears worn or damaged

Transmission-to-engine assembly error

Axle disengaged

Notes

Check the ATF level and check the ATF cooler lines for leaks and loose connections. If necessary, clean the ATF cooler lines.

Notes

Check for a loose shift cable at the shift lever and the selector control lever.

Notes

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.

Notes

Check the line pressure A/T Pressure Test.

Notes

Check the ATF strainer for debris. If the ATF strainer is clogged with particles of steel or aluminum, inspect the ATF pump. If the ATF pump is OK, find the damaged components that caused the debris. If no cause for contamination is found, replace the torque converter.

Notes

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.

Notes

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.

Notes

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.

Notes

Check for a incorrectly installed transmission
