Maybe you can also remember at least one transmission that was ruined as its owner fruitlessly tried to “rock” his car out of a snow bank. Smelly, burned transmission fluid, scorched clutch plates-you get the picture.
proper battery voltage and clean, tight connections in both the voltage supply and ground circuits of any car experiencing driveability problems. My own experience tells me that these factors are especially important when diagnosing any Porsche driveability complaint.
