Chrysler 300M / 300C Transmission Recalls

Recall 05V460000 / E14 – Transmission may not hold in the park position
2005 – 2006 Chrysler 300 – 2005 – 2006 Dodge Charger – 2006 Dodge Dakota – 2005 Dodge Durango – 2005 – 2006 Dodge Magnum – 2005 – 2006 Jeep Liberty – 2005 – 2006 Jeep Wrangler
Summary – In November 2005, Chrysler recalled 256,409 vehicles equipped with the 42RLE transmission, because the cup plug that holds the park prawl anchor shaft may not have been properly installed. If the shaft moves out of position, the vehicle may not be able to achieve the Park position.
Consequence – If this occurs and the parking brake is not applied, the vehicle could unexpectedly roll away, causing serious injury and damage.
Remedy – Dealers were instructed to install a bracket to ensure that the 42RLE parking prawl anchor shaft will stay in the proper position. Concerned owners may call Chrysler customer service at 1-800-853-1403 or NHTSA at 1-888-327-4236.

Chrysler 300M / 300C Technical Service Bulletins (TSB)

TSB 21-003-06 – Transmission shudder or buzzing noise due to water contamination
2005 – 2006 Chrysler 300
2005 – 2006 Dodge Magnum
2005 – 2006 Dodge Charger

-Note: This W5A580 transmission TSB is intended to supersede TSB 21-011-05 which included the 2005 Jeep Grand Cherokee

Problem – Owners may experience a shudder vibration and/or a high-frequency buzzing sound. This W5A580/NAG1 transmission problem may be most noticeable during light acceleration where partial application of the torque converter clutch happens in 3rd, 4th, or 5th gears. The reason this happens is because water has gotten past the transmission oil fill tube/dipstick seal. Contaminated transmission fluid can cause the TCC to stick and/or slip.

Solution – If the contaminated transmission fluid has not caused a lot of damage, the transmission and torque converter may be able to be flushed to cure the problem. However, if the contamination is severe, the torque converter will need to be replaced, and the transmission inspected for signs of other damage. The transmission fill tube seal will also need to be upgraded.

Can I drive with a transmission problem?

If your Chrysler 300 / 300M can still make it up and down the road, you might say “It’s fine, I’ll just drive it until I can get it fixed”. But that is not always a good idea, depending on the symptoms. You see, there are a lot of (very expensive) moving parts inside of a transmission, and if something isn’t right, continuing to drive with a transmission problem could damage something else.

How often does a Chrysler 300 / 300M transmission need to be replaced?

The overall lifespan of a Chrysler 300 / 300M transmission largely depends on how well it was maintained. Factory design flaws also factor into this equation, along with how/how hard you drive. But on average, we’ve seen the Chrysler 300 / 300M transmission last for between 130,000-180,000 miles. A high quality replacement transmission however, can last considerably longer if all of the factory design flaws have been addressed and the vehicle has been maintained.

How are Chrysler 300 / 300M transmission issues diagnosed?

It is fairly easy to guesstimate what the root cause of your Chrysler 300 / 300M transmission problems might be, but you won’t truly know unless you have the right tools and experience. A good mechanic or transmission repair center will be able to connect your truck to a computer and find out which diagnostic trouble codes (DTC’s) have been stored. Once they know what to look for, they can perform a visual inspection to verify the problem.

How is a Chrysler 300 / 300M transmission replaced?

In order to replace your Chrysler 300 / 300M transmission, the truck has to be lifted from the ground in order to gain access to all of the parts that will need to be unbolted. Then the transmission can be lowered to the ground (typically with a transmission jack), so the new transmission can be installed.

Recommendations for Chrysler 300 / 300M transmission issues?

To save time and get back on the road faster, have your 17-digit VIN# handy and you can get an online quote for a reman Chrysler 300 / 300M transmission here, then find a local shop using our Find a Shop guide to install it for you.

How to Solve Chrysler 300 / 300M Transmission Problems

Solution A: Buy a Used Chrysler 300 / 300M Transmission

The quickest way to fix your transmission problems is to simply buy a used transmission or used transmission. These can be found at most junk yards, and they often come with a 30-90 day warranty. However, there’s no way to determine the actual condition of the internal components, so you could be spending a bunch of money to have the exact same problems. Plus, that warranty only covers the transmission if it’s defective, not the labor costs that you’ll have to pay.

Solution B: Buy a Rebuilt Chrysler 300 / 300M Transmission

Another option would be a rebuilt transmission or rebuilt transmission. A local repair shop will remove your transmission, then install a bunch of new parts during the rebuild. The problem here is, the skills and experience of each transmission rebuilder will vary widely from shop to shop, so you could have problems from something that wasn’t adjusted properly. And the 1-2 year warranty might only cover you at certain transmission repair shops, in a specific geographical area.

Solution C: Buy a Remanufactured Chrysler 300 / 300M Transmission

Many owners depend on their vehicle to commute and get things done. Their gasoline engines are designed to go 100’s of thousands of miles, so it makes sense to invest in a remanufactured transmission.

Chrysler 300 stuck in park. Do you service?

Awanda Quick

I have a 2006Chrysler 300 and it says the tramission rally alway off what does that mean

James Quick

I have 2001 Chrysler 300 M I think it’s 42LRE trans. Iv had this prob for about 2 years. I’m a little embarrassed to say. But it goes into limp mode after it warms up about 15 miles In winter time. About 7 miles in summer time. Drives fine before that. shifts good No prob. After it warms up my rpm will drop to 0 and not move and can only go around 25 mph cuz it’s in 2 nd gear I guess. When I drive it like this some times it will pop out and start working again. Usually until the next stop then back in limp mode. My wife won’t drive it like that. But I will drive with hazard lights on in the right hand lane to get where I need to go. And yes about 2 years. Crazy and it’s my only Means of transportation. Can you help.
