• | Shift cable broken or out of adjustment |
• | Joint in the shift cable and the transmission, or body, worn |
• | ATF pump worn or binding |
• | Regulator valve stuck or the spring worn |
• | Mainshaft worn or damaged |
• | Final drive gears worn or damaged |
• | Park mechanism inoperative |
• | Transmission-to-engine assembly error |
|
• | Inspect the ATF level and ATF cooler lines for leakage and loose
connections. Flush the ATF cooler lines, if necessary. |
• | Inspect for a loose shift cable at the shift lever and transmission
control shaft. |
• | Improper alignment of the ATF pump and the torque converter housing
may cause an ATF pump seizure. The symptoms are mostly an RPM related ticking
noise or a high pitched squeak. |
• | Inspect the line pressure. |
• | If the filter is clogged, find the damaged components that caused
debris. |
• | Inspect the front differential pinion gears for wear. Replace
the front differential assembly, if the differential pinion gears are worn. |
• | Thoroughly clean the transmission, replace the ATF filter, and
flush the cooler and lines. |
• | Replace the torque converter. |
• | Do not damage the torque converter housing when replacing the
main ball bearing. Applying torque to the main valve body may damage the ATF
pump. Use the proper tools. This results in an ATF pump seizure, if not detected. |
• | Install the mainshaft front seal flush with the torque converter
housing. If the seal is installed down into the torque converter housing
until the seal bottoms out, the seal will block the fluid return passage and
result in damage. |
