7B1-118 AUTOMATIC TRANSAXLE (M13 ENGINE)
Unit Repair
When repairing automatic transaxle, it is necessary to conduct the on-vehicle test to investigate where the
cause of the trouble lies first.
Then whether overhaul should be done or not is determined. If the transaxle is disassembled without such pre-
liminary procedure, not only the cause of the trouble would be unknown, but also a secondary trouble may occur
and often time would be wasted.
Precautions
As the automatic transaxle consists of high precision component, the following cautions should be strictly
observed when handling its parts in disassembly and reassembly.
• Disassembling valve body assembly is prohibited essentially. However, a few parts can be disassembled.
When disassembling valve body component parts, confirm whether their parts are allowed to disassemble or
not referring to “Valve Body Assembly” in this section.
• Make sure to wash dirt off from the transaxle so that no such dirt will enter the transaxle during dismounting
and remounting.
• Select a clean place free from dust and dirt for overhauling.
• Place a rubber mat on the work bench to protect parts from damage.
• Work gloves or shop cloth should not be used. (Use a nylon cloth or a paper towel.)
• When separating the case joint, do not pry with a screwdriver or such but tap with a plastic hammer lightly.
• Make sure to wash dirt off from the transaxle so that no such dirt will enter the transaxle during disassembly
and reassembly.
• Wash the disassembled parts in ATF (Automatic Transaxle Fluid) or kerosene (using care not to allow ATF or
kerosene to get on your face, etc.) and confirm that each fluid passage is not clogged by blowing air into it.
But use kerosene to wash the discs, resin washers and rubber parts.
• Replace each gasket, oil seal and O-ring with a new one.
• Apply ATF to sliding or rotating parts before reassembly.
• A new discs should be soaked in ATF at least 2 hours before use.
