🔧 Step-by-Step Diagnosis
- Note the gear behavior - Document exactly which gears engage and which do not. The pattern tells the technician whether SS-A or another solenoid is the real problem.
- Pull pan and inspect solenoid pack - Visible heat damage, burned wires, or debris on the solenoid screens confirm the failure mode. Replace as a complete pack on most modern transmissions.
