Engine Runs, but Vehicle Does Not Move In Any Gear

Engine runs, but vehicle does not move in any gear

Transmission range switch broken or out of adjustment

Shift cable broken or out of adjustment

Connection between shift cable and transmission or shift lever is worn

Drive plate defective or transmission incorrectly installed

Torque converter clutch piston defective

Torque converter defective

Low ATF level

ATF pump worn or binding

Main regulator valve stuck or spring worn

Foreign material in separator plate orifice

Manual valve defective

ATF strainer clogged

Torque converter regulator valve defective

Mainshaft worn or damaged

Countershaft worn or damaged

Final gears worn or damaged

Park mechanism defective

Selector control shaft worn or damaged

Notes

Inspect the transmission range switch. If the transmission range switch fails the inspection, replace the switch. If the inspection is OK, check for proper transmission range switch installation, and adjust the shift cable.

Notes

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

Notes

Check for a incorrectly installed transmission, and check the drive plate for wear and damage. Replace the drive plate if it is worn or damaged.

Notes

Replace the torque converter.

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 the stall speed A/T Stall Speed Test.

Notes

Check the line pressure A/T Pressure Test.

Notes

Improper alignment of 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.

Notes

Check the main regulator valve in the regulator valve body for free movement. If the valve does not move, replace the regulator valve body.

Notes

Check for a clogged orifice in the separator plate. If the orifice is clogged, remove it and clean the separator plate orifice.

Notes

Check the manual valve in the manual valve body for wear and damage, and check the manual lever guide pin for wear and damage. Replace the manual valve body if the manual valve is worn and damage.

Notes

Check the ATF strainer for debris. If the strainer is clogged, find the damaged components that caused the debris. If no cause for contamination is found, replace the torque converter.

Notes

Check the torque converter regulator valve in the regulator valve body for free movement, and check the valve spring for wear and damage.

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 ATF cooler lines.

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 cause ATF pump seizure, 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

Inspect the mainshaft and the countershaft for wear and damage.

Notes

Inspect the park mechanism at the park lever link and park gear.
