Installation

1. Installation is the reverse of removal. CAUTION: If the oil seal on the transaxle case side is damaged and fluid is leaking, replace the oil seal with a new unit. When installing the new oil seal, use the specialized tool (oil seal installer, 09453-3L240). NOTE: After replacement or reinstallation procedure of the automatic transaxle assembly, must perform procedures below. Adding automatic transaxle fluid. Refer to «HYDRAULIC SYSTEM (FLUID)»(ref-429640-S06039938592011101500000) . After servicing the automatic transaxle or TCM, clear the diagnostic trouble codes (DTC) using the GDS tool. Diagnostic trouble codes (DTC) cannot be cleared by disconnecting the battery. When deleting diagnostic trouble code, use the GDS as possible. When replacing the automatic transaxle, reset the automatic transaxle's values by using the GDS. Perform TCM learning after replacing the transaxle to prevent slow transaxle response, jerky acceleration and jerky startup. Refer to «AUTOMATIC TRANSAXLE CONTROL SYSTEM (REPAIR PROCEDURES)»(ref-429641-S42222768972011101500000) .
