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 shift cable and transmission or shift lever is worn

Axle disengaged

ATF pump worn or binding

Regulator valve stuck or spring worn

ATF strainer clogged

Foreign material in separator plate orifice

Mainshaft worn or damaged

Countershaft worn or damaged

Final gears worn or damaged

Park mechanism defective

Selector control shaft worn or damaged

Drive plate defective

Torque converter defective

Transmission-to-engine assembly error

Notes

Check the ATF level, and check the ATF cooler line 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 transmission control lever.

Notes

Check the stall speed A/T Stall Speed Test.

Notes

Check the line pressure A/T Pressure Test.

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

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

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.

Notes

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 cause the 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 countershaft and the secondary shaft for wear and damage.

Notes

Inspect the park mechanism at the park lever link, park gear, and 2nd gears.

Notes

Check the drive plate for wear and damage, replace the drive plate if it is worn or damaged.

Notes

Check for a misinstalled transmission.
