Hence, there are some problems that users have been facing with the 300M tranny. But I think I have some solutions for you.

 So, why don’t we get straight into them!

Problem 1: The Chrysler 300M Transmission Disengaged

The 2000 Chrysler 300M transmission suddenly got disengaged. All gears including the reverse seem to have stopped working. And the car keeps turning off at high RPMs. 

Reason 1: Faulty Speed Sensor

It is something to do with the speed sensors. You can tell by looking at the speedometers. Check if they’re working fine, or have stopped working completely.


You can try to replace the speed sensors. That should solve any issues if the problem was with the speed sensors. Here’s a list of some of the speed sensors that are compatible with 2000 Chrysler 300M-

Reason 2: Malfunctioned Transmission

If not the speed sensors, something is wrong with the transmission mechanically. 


You will have to rebuild the transmission. It’s the only way to fix the disengaging problem. And you can ensure your Chrysler runs smoothly again. 

Reason 3: High Altitude Issues

The disengaging could also be due to driving at high altitudes. Areas with rough climate areas than usual can also cause this.

Unfortunately, there’s not much to do in this case. Because the problem lies with the build. 

However, you could probably see if Chrysler is offering upgraded parts for your transmission. That might solve the high altitude issue. 

Problem 2: The Chrysler 300M Transmission Sticks in 2nd Gear

Your Chrysler keeps getting stuck in 2nd gear. And when you shift to auto-stick, it still remains stuck. But while the RPMs can increase, the speedometer still remains null. 

Reason: Corroded Wirings

The issue is actually electronic. Basically what happened is, the wires in your transmission have probably gotten corroded. That or the wires are messed up in there and not how they should be. 


It’s best to take this problem to Chrysler and have them repair or replace the parts. You can easily do that if you have the warranty. And the safest thing to do is rebuild your transmission.

Similar electrical problems are also faced with the Ford Mustang as well. 

Problem 3: The Chrysler 300M Transmission Clunking Noise

In this case, the transmission changes seem to work fine, and the gears don’t slip. However, there’s a clunking sound.

Reason: Ill Attachment of the Half Shaft and the Output Shaft

There seems to be a lot of movement at a certain portion for the clunking sound. Basically in the place where the half shaft is attached to the output shaft. 

Even replacing the half shaft doesn’t make the clunking sound go away.


You need to bring the whole transmission out of the vehicle first. Then you need to rebuild it based on the differential. As that is what’s causing the clunking noise.

Now if you happen to be facing problems with your 2004 mazda transmission, don’t worry! We’ve got you covered on that too!

Other Problems you Could Face with your 2000 Chrysler 300M

Problem 1: The 2000 Chrysler 300M Steering Problem

There are other issues that are being faced with the steering when driving the Chrysler.

While taking right turns, there seems to be some sort of a popping or clunking noise. And sometimes the steering feels loose or gets stuck while making turns. As a result, the tires remain straight while the steering wheel is turned. 

While driving, the car seems to have lost all steering functions. And no warning signs are available to make you aware of the situation. 


The popping or clunking noise issue lies with the rack and the pinion.  The popping noise is caused by a broken bolt in the rack assembly. And a piece of the bolt is probably stuck in the assembly.  Sometimes the rack and pinion bolts get loose and back out of position. And that causes the steering to feel loose.


For the popping noise, you will need to repair the rack assembly. Or better yet get a replacement for both the rack and the pinion. That should solve the issue with the popping noise. 

You’ll need to tighten the bolts on the rack and pinion for the loose steering wheel. Make sure to do that from time to time, and you should be good to go!

I’ve personally used these two wrenches while working in my personal workshop. So, you can try them out as well. I don’t think you’ll be disappointed.

Problem 2: The 2000 Chrysler 300M Airbag Problem

A crack seems to have appeared in the airbag cover on the front passenger side. Basically, the airbag storage is starting to slowly split open. 

Therefore, the airbag might not perform its job in case of an accident. 


This is usually caused due to extreme heat that causes the dashboard to crack. And that is usually where the airbag is stored and gets exposed to the sun. The crack might also cause the airbag to fail to deploy in emergencies. 


You could go to your local Chrysler dealer and seek a replacement for the cracked dashboard. But if your local Chrysler dealer can’t help you, get a vinyl repair done for the cracks.

However, keep in mind that still doesn’t rid your confusion regarding airbag deployment. And might have the opposite effect on the deployment, which may have been fine, to begin with. 

Nevertheless, occasional maintenance for your 2000 Chrysler 300M transmission should always come in handy. It and be helpful to prevent or at least identify these issues before accidents happen!
