Dodge Challenger Transmission Recalls

Recall 08V458000 – Park/neutral start switch
2008 – 2009 Dodge Challenger SRT
2009 Dodge Challenger SE
2009 Dodge Challenger R/T
Summary – Chrysler recalled 6,636 copies of the Dodge Challenger fitted with the W5A580 transmission and the Keyless Go pushbutton ignition option. It seems the stop/start button can be pressed and held, turning off the engine even when the shifter is not in the Park position.
Consequence – If the transmission is not in Park when the engine is turned off, the car could unexpectedly roll away, causing serious injury and property damage.
Remedy – Dodge dealers were instructed to reprogram the wireless ignition node module so that the engine can only be turned off when the transmission and gearshift are in the Park position. This we called was issued in September 2008. Concerned owners can contact Chrysler customer service at 1-800-853-1403. Refer to recall H29. You can also contact the National Highway Traffic Safety Administration at 1-888-327-4236

Can I drive with a transmission problem?

If your Dodge Challenger 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 Dodge Challenger transmission need to be replaced?

The overall lifespan of a Dodge Challenger 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 Dodge Challenger 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 Dodge Challenger transmission issues diagnosed?

It is fairly easy to guesstimate what the root cause of your Dodge Challenger 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 Dodge Challenger transmission replaced?

In order to replace your Dodge Challenger 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.

How to Solve Dodge Challenger Transmission Problems

Solution A: Buy a Used Dodge Challenger 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 Dodge Challenger 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 Dodge Challenger 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.
