On my 1990 Voyager, the transmission has a "safe," or "limp" mode. If something is wrong with the trans, it will not shift out of second gear. This is supposedly to allow you to drive to the repair shop at a reduced speed.
depends, what kind of trans is if, if its a 3speed then that's as far as it should go. Have the engine and trans computers checked for trouble codes. The 4 speed will not shift when the computer detects a problem and sets a code.
The crankshaft positioning sensor is located between the engine and the transmission about one third way down looking from inside top of engine. It is not easy to find. You are looking for a connector wire with the sensor, it is bolted onto the transmission with a 10MM bolt.
The 2000 Plymouth Voyager 2.4 liter engine radiator cooling fan relay switch can be found in the fuse box. The relay switch will be in the third column, fourth from the top.
If your transmission is not shifting into third gear and overdrive it could be a parking pawl. This prevents the transmission from rotating.
Could be low fluid,a bad sensor or transmission going bad.
The transmission shift solenoids are bad!!
it maybe the alternator... warranty will cover you
check fuses check for 12v supply at transmission-- wire @ 12 oclock on trans connector
Damaged/broken shift forks
Are you sure that it's third it's not shifting into, and not fourth? The transmission is designed to not permit shifts into fourth (overdrive) until the engine and transmission have warmed up a bit.
The Third Shift was created in 2004.
Is there a button to activate the overdrive on the transmission. If the button is activated and not in overdrive mode the car will never shift into 4th gear.
