• Q: How to Service and Repair the Transmission Pan, Gasket, and Filter of the 4R70W Automatic Transmission on 2001 Ford Expedition?

  A: Changing automatic transmission fluid becomes essential when servicing the fluid pan gasket filter and when major repairs such as clutch bearing replacements warrant transmission removal. A complete cleaning of both the torque converter and transmission cooler along with the tubes becomes necessary for the removal of dirt particles so the fluid requires replacement when contamination exists. The specified fluid is essential for transmission operation so always check the vehicle certification label at the door lock face panel or door pillar. The specified fluid capacity determines transmission filling procedures while you should verify the fluid level reaches its proper mark as well. The first operation starts with disconnecting the ground cable while supporting the vehicle in the air followed by placing a drain pan beneath the transmission fluid pan to drain out the fluid. You should loosen the bolts from the transmission fluid pan until all liquid drains out fully before removing them to take off the pan and gasket. First drain transmission fluid by removing the filter components and severely tighten the torque converter housing plug and drain plug. To reach the drain plug you may need to rotate the crankshaft. The technician should clean the fluid pan along with its gasket and magnet before flushing tubes from the fluid cooler system. Install a new torque converter drain plug followed by installation of the housing plug. When installing a new filter, extract the main control bore seal without harming it while replacing with new components unless there was no contamination present. In this case, the filter should be reused if it does not show major contamination. Install the pan magnet into the fluid pan then examine the gasket for breaks before mounting the pan with its gasket followed by the bolts. You should reconnect the battery ground cable to your vehicle but remember that adaptive strategy learning will cause abnormal driving symptoms which need up to 16 km (10 miles) of continuous driving to correct themselves. For those filling their dry transmission system start with 4.7 liters (5 quarts) of clean fluid before filling it to the required level.
