Thanks, Matt.
So when they do the scan, will it track down which of these errors may exist, or do the technicians need to check all of these conditions (that sounds time consuming)...
When they connect a scanner - it may indicate a possible trouble code...
ie. DTC P0741 displayed as a stored code would point them to:
DTC P0741
Circuit Description
The transmission control module (TCM) uses data from the engine speed sensor and the input speed sensor to calculate torque converter slip value. The TCM then compares this calculated slip value to a preset value in the TCM calibration.
Diagnostic Aids
Inspect the wiring for poor electrical connections at the TCM. Inspect for the following conditions:
A bent terminal
A backed-out terminal
A damaged terminal
Poor terminal tension
A chafed wire
A broken wire inside the insulation
When diagnosing for an intermittent short or open, massage the wiring harness while watching the test equipment for a change.
You may have to drive the vehicle in order to experience a condition.
