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.
