Metric tools will be required to service this transmission. Due to the large number of alloy parts used in this transmission, torque specifications should be strictly observed. Before installing capscrews into aluminum parts, dip the bolts into clean transmission fluid as this will prevent the screws from galling the aluminum threads, thus causing damage.
Metric fastener dimensions are very close to the dimensions of the familiar inch system fasteners. For this reason replacement fasteners must have the same measurement and strength as the original fastener.
Do not attempt to interchange metric fasteners for inch system fasteners. Mismatched or incorrect fasteners can cause damage to the automatic transmission unit and possible personal injury. Care should be taken to reuse fasteners in their original locations.
