Cleaning After Disassembly

CAUTIONDo not clean the following parts, otherwise foreign matter or degreaser may penetrate the oil passage or internal part: Control valve body (including the following parts:) ON/OFF solenoid Oil pressure switch A Oil pressure switch B Coupler component
  1. Clean the torque converter. (See «TORQUE CONVERTER CLEANING»(ref-537680-S05942292462013032500000) .) CAUTION: To prevent damage to the parts, do not clean the inside of the torque converter using degreaser.
  2. Clean the oil cooler. (See «OIL COOLER CLEANING»(ref-537680-S32814902912013032500000) .) CAUTION: To prevent damage to the parts, do not clean the inside of the oil cooler using degreaser.
  3. Flush dirt on the surface of the drive plate with ATF (ATF FZ). CAUTION: To prevent damage to the parts, do not clean the drive plate using degreaser.
  4. Clean the disassembled parts using degreaser and dry them using an air compressor. In addition, clean the oil passage using the air compressor. WARNING: Always wear protective eye wear when using the air compressor. Otherwise, ATF or dirt particles blown off by the air compressor could get into the eyes. CAUTION: To prevent damage to parts, do not clean aluminum and rubber parts using alkaline agent. To prevent damage to parts, do not clean rubber parts using white gasoline and kerosene.

  1. Remove the ATF or foreign matter adhering to the outside of the transaxle using degreaser or the air compressor. WARNING: Always wear protective eye wear when using the air compressor. Otherwise, ATF or dirt particles blown off by the air compressor could get into the eyes. CAUTION: If foreign matter, water, or degreaser penetrates the transaxle and connector, it could cause a malfunction. Before cleaning the outside of the transaxle, plug the position shown in the figure with the packing tape. (Scheme 1465): Identifying Breather Pipe, Control Valve Body Connector, Oil Cooler And Seal
  2. Verify that there is no ATF or foreign matter on the connector shown in the figure. Control valve body connector If there is ATF or foreign matter on the connector shown in the figure, remove it. (Scheme 1466): Identifying Control Valve Body Connector

Disassembly Procedure

CAUTIONDisassemble the control valve body and replace the malfunctioning part only if there is a malfunction in the control valve body determined by the troubleshooting procedure and using the vehicle diagnostic tester (M-MDS). However, if there is a malfunction in the parts other than the following, replace the control valve body with a new one because the parts other than the following are not shipped from the factory as a single component. ON/OFF solenoid Oil pressure switch A Oil pressure switch B Coupler component Do not drop or apply an impact to the control valve body. Replace the control valve body with a new one if it was dropped or received an impact. Placing the TCM side pointed downward on a workbench directly could damage the TCM. If the TCM side is placed pointed downward, place the control valve body on an impact-absorbing material so that the TCM does not contact the workbench directly. A: TCM B: Impact-absorbing material
