I have a1992 dodge caravan 3.3 se. engine ran fine, but transmission was failing after approx. 100 ft. all gears where disengaged including reverse. Turning off the engine for a minute or so and starting again the same thing happened over and over again. The next day the battery was dead and would not hold a charge. I replaced the battery but still had the same result. Is this a sensor, or what, problem? Help.............., Bill
