The transmission is not causing the engine to die.
Some old cars don't like to go over 27 without a tune up. It could be a
fuel or electrical problem, but your husband will need to take/bring
the car to someone with equipment to diagnose it. People here could
help perhaps, but that would require information from you that we could
not hope to obtain in this lifetime.
