Operational Test Description

DESCRIPTION
Operational test procedures serve as pre-road test checks. Procedures are conducted in the service facility using minimal time and less effort than the road test. These procedures determine causes of (and provide corrective actions for) the most likely transaxle malfunctions. These include torque converter, friction elements (clutches and bands), hydraulic system, and associated regulating valves and controls.
