Transaxle

CAUTION:To prevent dirt from entering the transaxle, it should be disassembled and kept in a clean area. Remove the torque converter, taking care not to spill the transmission fluid. Before disassembly, clean the outer surface of the transaxle by using steam, cleaning fluid, etc.

CAUTION:During disassembly, avoid using rags that can leave fabric particles on components as this can block passages and cause valves to stick. Clean the disassembled parts, and clean the oil passages with compressed air and check to be sure they are not clogged.

Note:The casings allow separate repairs to be carried out on either the automatic transaxle or the final drive section. When a problem exists that only requires work on one section, separate the transaxle. Cover the section not requiring attention to prevent foreign material from entering the assembly.
