Intermittent fault

Check the cable between transmission control module (TCM) #A50 and transmission connector A #21 for an intermittent open-circuit according to Open-circuit, intermittent faults and contact resistance and oxidation according to Contact resistance and oxidation .

HINT: Check solenoid S1 by measuring the resistance between transmission connector #21 and the transmission housing. Resistance should be 12-18 Ω (at 20◦C) 

Remedy as necessary.
