- Check ATF level and check ATF cooler lines for leakage and loose connections. If necessary, flush ATF cooler lines.
- Check for a loose shift cable on the shift lever and the transmission control shaft.
- Improper alignment of ATF pump and torque converter housing may cause ATF pump seizure. The symptoms are mostly an rpm-related ticking noise or a high pitched squeak.
- Measure line pressure.
- If the strainer is clogged, find the damaged components that caused debris.
- Inspect the differential pinion shaft for wear under the pinion gears. If the differential pinion shaft is worn, overhaul the differential assembly, replace the ATF strainer, thoroughly clean the transmission and flush the torque converter, cooler and lines.
- 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.
- 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.

- Check for a loose shift cable on the shift lever and the transmission control shaft.
- Inspect the mainshaft and 1st clutch assembly for wear and damage.
- Inspect the clutch piston, clutch piston check valve and O-rings. Check the spring retainer for wear and damage. Inspect the clutch end plate-to-top disc clearance. If the clearance is out of tolerance, inspect the clutch discs and plates for wear and damage. If the discs and plates are worn or damaged, replace them as a set. If they are OK, adjust the clearance with the clutch end plate.
