Question

Quizplus · Accepted Answer

Both Tech A and Tech B could be correct. A failed limp home solenoid can prevent the vehicle from moving by not allowing the transmission to engage properly. Similarly, if the pump has failed and locked up, it can also prevent the vehicle from moving by not circulating transmission fluid, which is necessary for the transmission to function.
