Intermittent fault
Check the wiring between transmission control module (TCM) terminal #A52 (#A52) and transmission connector terminal #D3. Check the wiring between control module terminal #B10 (#A70) and transmission connector terminal #D4. Check for an intermittent short-circuit to supply voltage. See Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Hint: Check solenoid SLT. Measure the resistance between terminals #D3 and #D4 on transmission connector D. The resistance should be 5-5.6 ohms at 20°C.
Remedy as necessary.
