Are RAMs known for transmission problems?
Yes, RAM trucks have had transmission problems in certain generations, especially with older heavy‑duty models that used earlier automatic transmissions. Reliability has generally improved in newer RAMs, but issues can still surface, particularly under heavy towing or high mileage.
This article examines the history, which models were affected, common symptoms, and practical steps for owners or prospective buyers to assess and address transmission concerns in RAM vehicles.
Historical overview of RAM transmissions
Below is a snapshot of generations and transmissions most frequently cited in reports and owner feedback for problems.
- Older heavy‑duty RAMs that used the 46RE/47RE/48RE transmission family. These units are well documented in vintage owner forums and reliability reviews for issues such as valve body wear, timing of shifts, and overheating under heavy towing conditions.
- The 68RFE transmission (a six‑speed unit used in many RAM 2500/3500 builds over a wide span) has been the subject of numerous complaints, particularly related to harsh or delayed shifts, slipping, and torque‑converter behavior when towing heavy loads.
- Some newer RAMs adopted eight‑speed automatic transmissions (including models that share some components with other brands). Early software calibration and transmission control module updates were common, with improvements typically implemented through dealer service bulletins and recalls. These units tend to be more reliable after updates, but early production runs saw quirks that prompted owners to seek fixes.
Summed up, RAM transmission reliability has varied by generation. The pattern seen in industry feedback is a deterioration in reliability during older, heavy‑duty configurations, followed by improvement as newer eight‑speed designs were introduced and refined through software updates and recalls.
Common symptoms to watch for
The following signs are frequently reported by RAM owners as potential transmission trouble. Not every symptom means a full failure, but they warrant inspection by a qualified technician.
- Harsh, delayed, or slipping shifts between gears, especially under load or during acceleration.
- Unusual noises ( whining, clunking, or grinding) coming from the transmission area.
- Transmission warning light or check engine light activating with related fault codes.
- Overheating symptoms or a noticeable burnt‑fluid smell, sometimes alongside reduced transmission performance.
- Rough engagement into gear, or the transmission failing to upshift or downshift smoothly in certain driving conditions.
- Torque‑converter related issues such as shudder or poor towing performance.
Owners facing these symptoms should prioritize a professional diagnosis, as early interference can prevent more serious damage and expensive repairs.
What to do if you suspect RAM transmission problems
If you notice signs of transmission trouble, follow these steps to protect your vehicle and your investment.
- Check for open recalls and service bulletins for your exact model year and transmission type. Contact the dealer or use official recall databases to verify status.
- Review maintenance history and ensure the correct transmission fluid and service intervals have been followed. Use the fluid type recommended by RAM for your transmission family, and avoid DIY shortcuts that can cause harm.
- Have a qualified technician perform a diagnostic scan, including live data and transmission-specific fault codes, to pinpoint whether the issue is electronic, hydraulic, or mechanical.
- Assess the need for warranty coverage or extended service plans. If symptoms emerged under warranty or during a known recall, factory coverage may apply.
- Be prepared for diagnostic road tests and potential component inspections (valve body, solenoids, torque converter, and seals) if a failure isn’t immediately evident from codes alone.
Addressing transmission issues promptly can prevent more extensive damage and help you determine whether repair, rebuild, or replacement is the best long‑term solution.
Bottom line
RAMs have a mixed reliability record when it comes to transmissions. Older heavy‑duty configurations (notably 46RE/47RE/48RE and 68RFE variants) are the most frequently cited sources of problems, particularly under strenuous use. Newer eight‑speed units have shown improved reliability after software updates and refinements, but potential owners should verify model‑year specifics, maintenance history, and recall status before purchase. For current owners, routine maintenance and prompt professional diagnostics are key to avoiding costly failures.
Summary
In short, RAM transmission problems are not universal across the lineup, but they have a documented history in several generations—especially older heavy‑duty models. Buyers and owners should stay informed about the exact transmission type in their RAM, review recall and service bulletin data, and maintain proper fluid and service intervals. When problems arise, early diagnosis and professional repair decisions are the most reliable paths to keep RAM trucks performing as intended.
