98 Plymouth Voyager gets stuck in gear until I turn it off and on
if it gets stuck into second, on a dodge this is called limp mode. two sensors on the front of trans accesible by removeing the air box only. they have a black/cream colers face with 2 wires on each. the one by the engine is the input speed sensor(turbine rpm) the one towards the wheel is the output. if the output fails the speedo will stop working and trans will slam into second. if input goes will fault the same but no indicators. the pigtail wires break after yeas of flexing also. pigtails and sensors are avail anywhere sensor is about 20 bucks just specify in or out put. u can test too by unplugging test the sensor w a ohm meter on lowest avail scale, if any reading-its good, if overload-its pooh. this is if its a A604 4speed trans, pans is square w engine side of pan has a squiggle in it. and that trans buzzes when put into gear(normal) now if its a A670 3 speed trans, which is all mechanically controlled, there is a cable/linkage that goes from the engine throttle body down to the trans. on the trans shifter input shaft, its hollow, there is another shaft inside. this moves w the gas pedal to tell the trans how long to wait to shift and how hard to shift. the shaft on the trans get rusty and seized all the time on these. wd-40 the heck out of it and work it back and forth untill it moves freely independent of the shifter linkage. it only is moved by the throttle one way so the spring cant return it on its own when it starts rusting up... pheww- i hate typing this trans has a perfectly rectangular pan. good luck and let me know what you come up with!
