2005 e250 transmission won't change to 4th speed

Depending on your transmission it should be mounted on the tail shaft. I attached a picture of a 4wd transmission. I hope this helps.

05 Chrysler pacifica is a 4 speed automatic, next time buy a car with a 5 speed automatic

When did you last replace trans filter and fluid? Dirt may be causing shift valve to stick.

EASY ONE.... Your VSS (Vehicle SPEED SENSOR) stopped working and it is this Sensor that gives the PCM/ECM the information to change gears. Once you change your VSS, and get it working, the Transmission will start working again...

I am Assuming that the Transmission stopped working at the same time the Speedometer did? Is that right?

If it is, then this is a easy fix. 1 bolt and one Wire Connector and DONE....

This transmission is electronically shifted via solenoids controlled by a computer, so you need to have that tested for fault codes that may be in memory.

your shifter cable is going bad.

Check transmission fluid. If that is full, try changing the fuel filter. It could be starving for gas, and trying to shift but can't. It could also be the speed sensor, or shift solenoid.

Give it a transmission tune-up, Dexron III oil, Lucas for transmission and transmission filter. Check the fluid level, restart the computer go for a ride. Check the fluid level again and continue to drive, it'll get better when the computer sets. I suggest you change the air filter, engine oil and filter, fuel filter etc. Just give it a tune-up!

First thing to do is check the fluid level if that ok you may want to think about having the transmission filter and fluid changed, there are other possibilities but check these first
