Remanufactured Dodge Challenger Transmissions 


Launched for the 2008 model year, the Dodge Challenger is one of the most iconic and popular models in the Mopar lineup. It could be had from mild-to-wild, thanks to a number of available engines. As far as Dodge Challenger transmissions go, there were several offered; the 42RLE transmission, and the W5A580 transmission (NAG1). These are fairly reliable gearboxes for the most part. However a number of transmission problems may require the installation of a remanufactured Dodge Challenger transmission. So let’s find out if that’s what you need to do. 



Common Dodge Challenger 42RLE Transmission Problems  


Poor Shifting Quality 

If you experience poor shifting quality with your 42RLE transmission, you may need to check the fluid levels. If low levels are not the problem, you may have a solenoid or valve stuck in the valve body, a computer malfunction, or a pump that is starting to fail. 


The Transmission is Stuck in Second Gear 

Typically, if you have noticed the transmission is stuck in second gear, it is likely that the transmission has gone into limp home mode. This mode is a safety measure that Chrysler built into the transmission that allows you to continue to drive your vehicle to a service station without completely destroying the transmission. If you experience this problem, it is likely that it can be traced back to a defective sensor. 


The Transmission Randomly Downshifts without Engaging Properly 

This is a common problem that can be traced back to a defective lower or upper speed sensor. 


The Transmission Starts to Experience Harsh 1-2 Shifts 

Many times, a filter and fluid change will correct this issue. You should always use the correct fluid in your 42RLE transmission to prevent further damage to it. It is recommended that you have a power flush performed to ensure all old debris and fluid is removed from the transmission. 


The Transmission is Overheating 

This is a common problem in most automatic transmissions, but the 42RLE does seem to experience it more often. It is recommended that you install an aftermarket transmission cooler to combat the problem. 


Shifting problems and solenoid/pressure switch DTCs – 42RLE transmission 
Problem – Drivers may experience 42RLE transmission problems that include slipping and harsh shifts. The check engine light may also be illuminated with the following codes stored in the ECU: P0750, P0755, P0760, P0765, P0846, P0871, P0841. 
Solution  The problem may be caused by corrosion in the 10 pin solenoid harness connector. This may also be caused by a wiring issue between the TCM/ECU and the transmission harness connector. A new design 42RLE 10-pin connector will need to be installed and/or wiring issues repaired. 



Common Dodge Challenger W5A580 Transmission Problems  


Slipping, Erratic Shifting, Harsh Forward or Reverse Gear Engagement: Some of the most common W5A580 transmission problems are slipping between gears, erratic up or down shifts, or a hard slam when the W5A580 transmission engages Drive or Reverse. There are a number of design flaws in this transmission, and any one of them could be causing these symptoms. 


Another common problem is overheating. This happens when the moving parts inside the transmission are creating more friction heat than the ATF can remove. The most common cause of this condition is towing heavy loads, driving in stop/go traffic, or on mountain roads where the transmission has to shift a lot. 


How to Solve Dodge Challenger Transmission Problems 


Solution A: Buy a Used Dodge Challenger Transmission 

Going to the local junkyard and picking up a used 42RLE transmission or W5A580 transmission might seem like the cheapest and fastest option. But you need to consider the fact that you don’t know what the actual shape of the internal components are. It could very well be on the verge of transmission problems of its own, which would leave you in the exact same predicament that you’re in now. And that 30 – 90 day junkyard warranty probably won’t cover labor charges to install the replacement transmission if something goes wrong. 


Solution B: Buy a Rebuilt Dodge Challenger Transmission 

Getting a rebuilt 42RLE transmission or W5A580 transmission would probably seem like a better idea. However, a lot of mechanics and transmission shops will only rebuild your Dodge Challenger transmission back to its original factory specifications. Which means that all of those factory design flaws are still going to be inplay. And that rebuilt transmission warranty might only be good at certain shops, which could do you no good if you have transmission problems while you’re traveling. 


Solution C: Buy a Remanufactured Dodge Challenger Transmission 

If you want to get the most service life out of your little luxury SUV as possible, then you really should consider a remanufactured Dodge Challenger transmission from Street Smart Transmission. Each one is completely disassembled and re-remanufactured, so nothing is left to chance. Theyre also modified to correct the factory design flaws, which will greatly extend the service life. Plus, you get a 3-Year/Unlimited Mile Nationwide Warranty. This will cover parts and labor charges at any licensed repair shop in the Continental United States, giving you a lot more flexibility and coverage.
