• Q: How to Service and Repair the Automatic Transmission Filter for the 3T40 on 2001 Chevrolet Cavalier?

  A: The 3t40 automatic transmission fluid/filter requires servicing by first supporting the vehicle at a raised position. Position a drain pan beneath the transmission Oil Pan and remove the bolts at the front and sides first before lightly loosening the bolts fitted at the pan's rear by four turns. Careful downward prying of the Oil Pan needs to happen before damage occurs to transmission case or Oil Pan sealing surfaces but not enough to strain the rubber mallet contact point. Start by removing the remaining Oil Pan bolts before removing both the Oil Pan with its gasket. Remove the Oil Filter then its o-ring seal from the case before checking the o-ring seal for debris clinging inside. First clean both transmission surfaces and the Oil Pan gasket areas with solvent until no traces of old materials remain while allowing the components to dry naturally. Check the Oil Pan for leakage potential because any broken or damaged areas require replacement. The installation process requires j36850 (J36850) or its equivalent to coat both new filter components before placing them into the case with its new Oil Pan gasket. The Oil Pan installation requires inspection of bolts with washers while using adhesive and sealant compound gm p/n 12345382 (12345382) or equivalent. Drive the vehicle to a low position while tightly torquing Oil Pan bolts to 10 nm (89 inch lbs.). The transmission requires dexron iii oil filling to a specific level but keep away from excessive fluid because it leads to foam production and fluid loss and transmission complaints as well as possible transaxle damage. End the inspection by checking the Oil Pan gasket for possible leakage.
