Clutch and Band Charts
Application charts are used to quickly pin point the area of an automatic transmission that’s causing a shifting problem. Through a process of elimination the faulty component can be located using this handy tool.
The vehicle’s transmission slipped and neutralized in second gear and seemed to have no overdrive. After a test drive the technician retrieves the solenoid, clutch and band charts to find which devices are applying or holding in the gear or gears associated with the problem. Notice a slipping 2-4 band would certainly result in a slip in second and forth gear.
