DIAGNOSIS AND TESTING > DIAGNOSTIC STRATEGY > PINPOINT TESTS
The pinpoint tests are divided by component or system. Each test is a series of circuit checks to verify the integrity of the wiring harness between the PCM/ TCM and the solenoid or sensor.
DIAGNOSIS AND TESTING > DIAGNOSTIC STRATEGY > COMPONENT TESTS
The component tests are divided by system. Each test lists the possible symptoms the system can exhibit. For each symptom is a list of components that could cause the symptom. The components are listed in least intrusive to most intrusive order.
DIAGNOSIS AND TESTING > DIAGNOSTIC STRATEGY > PERFORM REPAIR
There are over 400 individual components in an automatic transmission. All of these parts must be in good working order. Many repairs are fairly straight forward. In these repairs you will:
Clean and inspect all parts removed
Attempt to determine root cause of the failure
Identify and repair/replace any related damaged parts
Carefully document findings on the repair order
In the case of clutch failure where the transmission fluid is heavily contaminated with friction material, the transmission needs to be overhauled. The repair will require complete disassembly and cleaning of the transmission. All seals and gaskets (except the reusable pan gasket) should be replaced.
DIAGNOSIS AND TESTING > DIAGNOSTIC STRATEGY > COMPLETE REPAIR
After reassembling the transmission, several steps are required to properly restore the vehicle before returning it to the customer.
Initial transmission fluid fill - this may be completed before the transmission is installed in the vehicle
Clear adaptive tables - required for overhaul and when the solenoid body has been replaced
Reset misfire monitor - required whenever the transmission has been removed
Road Test until the transmission fluid is up to operating temperature, this is required to make sure transmission fluid cooler is full of transmission fluid
Perform adaptive drive cycle - required if the adaptive tables were cleared
Set transmission fluid level - transmission fluid is now at the correct temperature and that the
