Remanufactured Ram 1500 Transmissions 


From its looks and features, to its classleading performance, the Ram 1500 is possibly the most Murican of American full-size trucks. However, Ram 1500 transmission problems with the 545RFE or 65RFE can certainly hurt its sterling reputation. So let’s see if installing a remanufactured Ram 1500 transmission can restore its ram tough” reputation. 


Common Ram 1500 545RFE Transmission Problems  


Delayed and/or harsh 3-4 or 4-5 shifts 

Problem – Owners may experience an unusually delayed or harsh 3-4 or 4-5 gear change, where the transmission doesnt seem to want to go into that particular gear. 

Solution  This issue is related to valve body problems where the material used to make one of the checkballs has broken down to the point that fluid is able to get past and engage the underdrive clutch during those shifts. An upgraded #2 checkball will be needed to solve the issue. 


Solenoid Pack: With no transmission bands, the electronically controlled 545RFE relies on a solenoid switch pack to direct fluid to the correct clutch pack for gear engagement. If the solenoid pack goes bad, youll experience no gear engagement, engine stalling, limp mode, or failure to engage overdrive. 


Slipping and Delayed Gear Engagement: The transmission pump has a little valve mechanism inside it, which controls the fluid pressure being transferred from the torque converter. If it goes bad, youll have delayed gear engagement, transmission/torque converter overheating, stalling, slipping, and reduced fuel economy. 


Common Ram 1500 65RFE Transmission Problems  


Slipping, Erratic Shifting, Harsh Forward or Reverse Gear Engagement 

Some of the most common 65RFE transmission problems are slipping between gears, erratic up or down shifts, or a hard slam when the 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 Ram 1500 Transmission Problems 


Solution A: Buy a Used Ram 1500 Transmission  

Going to the local junkyard and picking up a used Ram 1500 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 Ram 1500 Transmission  

Getting a rebuilt Ram 1500 transmission would probably seem like a better idea. However, a lot of mechanics and transmission shops will only rebuild your Ram 1500 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 Ram 1500 Transmission  

If you want to get the most service life out of your vehicle as possible, then you really should consider a remanufactured Ram 1500 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.
