Ram 1500 Transmission Recalls & Known Problems
Recall 14V-161 / P13 – Failed Park engagement
2014 Ram 1500 5.7L Hemi and 8-speed automatic transmission
Summary – According to the recall, some 125 copies of the 2014 Ram 1500 equipped to with the 8HP transmission may have had improperly machined Park rod guide plate mounting surfaces inside of the transmission case, which could cause the fasteners to loosen, preventing the Park prawl from fully engaging.
Consequence – If the above condition occurs, the transmission may slip out of the park position and unexpectedly roll away, causing serious injury or property damage.
Remedy – The transmission will have to be replaced. Concerned owners can contact Chrysler customer service at 1-800-853-1403. You can also contact the National Highway Traffic Safety Administration at 1-888-327-4236
Ram 1500 Technical Service Bulletins (TSB)
TSB 21-010-12 – Clunk noise when shifting from drive to neutral – 65RFE transmission
2011 – 2012 Ram 1500 – 2011 – 2012 Ram 2500 – 2011 – 2012 Ram 3500 Cab Chassis – 2011 – 2012 Dodge Durango – 2011 – 2012 Jeep Grand Cherokee
Problem – Drivers may notice a pronounced clunking noise when shifting from drive to neutral. This may be particularly evident when the vehicle is hot or at normal operating temperatures.
Solution – These 65RFE transmission problems may be caused by the underdrive clutch releasing too quickly. To correct the issue a revised spacer plate will need to be installed inside of the valve body.
TSB 21-004-17 – Low/reverse solenoid failure – 65RFE transmission
2016 – 2017 Ram 1500 – 2016 – 2017 RAM 2500 – 2016 – 2017 Ram 3500 – 2016 – 2017 Ram 3500 Cab Chassis
Problem – Drivers may experience extreme difficulty and/or the inability to engage Drive or Reverse.
Solution – These 65RFE transmission problems could be due to the premature failure of the low/reverse solenoid assembly.
Common Ram 1500 Transmission Problems
Delayed and/or harsh 3-4 or 4-5 shifts – 545RFE Transmission
Problem – Owners may experience an unusually delayed or harsh 3-4 or 4-5 gear change, where the transmission doesn’t 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.

Can I drive with a transmission problem?
If your Ram 1500 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 Ram 1500 transmission need to be replaced?
The overall lifespan of a Ram 1500 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 Ram 1500 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 Ram 1500 transmission issues diagnosed?
It is fairly easy to guesstimate what the root cause of your Ram 1500 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 Ram 1500 transmission replaced?
In order to replace your Ram 1500 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 Ram 1500 Transmission Problems
Solution A: Buy a Used Ram 1500 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 Ram 1500 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 Ram 1500 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.
