Do Dodge Rams have transmission problems?
Yes—some Ram trucks have had transmission problems, particularly in certain model years and with specific transmissions; however, many owners report reliable performance, and improvements have been made in newer generations.
This article examines the history of Ram transmission issues, identifies which model years and transmission types have drawn the most attention, outlines common symptoms, and offers guidance on diagnosing and addressing potential problems. It aims to present an up-to-date, balanced view for current owners and buyers alike.
Transmissions used in Ram trucks and when problems appeared
Overview of the main transmissions in Ram trucks and the years when owners reported notable issues.
- Older Ram models used five- and six-speed automatics (such as the 545RFE/68RFE family). These units were known to exhibit harsh or delayed shifts, slipping, torque-converter problems, and overheating under heavy tow or load conditions.
- The eight-speed automatic family (ZF-based 8HP70/8HP45 and related variants) began appearing in Ram 1500s around 2013 and later expanded to heavier-duty trucks. These transmissions improved efficiency and performance, but some early and mid-generation units faced reports of harsh or shuddering shifts, torque-converter issues, and occasional calibration glitches that prompted software updates from dealers.
Conclusion: Transmission reliability in Ram trucks has varied by generation. While newer eight-speed designs generally offer improved performance, older five- and six-speed units in certain model years are more commonly associated with shifting and durability concerns.
Common symptoms to watch for
Before diagnosing a transmission problem, look for these telltale signs that have appeared in owner reports and service inquiries.
- Harsh, erratic, or delayed upshifts or downshifts, especially when accelerating or decelerating.
- Slipping out of gear, inability to hold a gear under load, or abrupt gear changes at low speeds.
- Torque-converter shudder or lock-up issues that accompany vibrations or unusual engine RPM behavior.
- Delayed engagement when shifting from Park or Neutral into Drive or Reverse, or unusual noises (whining, clunking) during operation.
Conclusion: If you notice these symptoms, it is advisable to have the vehicle inspected promptly. In many cases, issues may be addressed with software updates, fluid service, or valve-body calibration, but some conditions can require more extensive repairs.
What to do if you suspect a problem
Warranty coverage, recalls, and maintenance steps
Owners should start by checking for active recalls and Technical Service Bulletins (TSBs) that cover transmission concerns for their specific model year. Many fixes have been implemented under warranty or through service campaigns.
- Verify service history and confirm whether any transmission-related recalls or TSBs have been completed.
- Follow the manufacturer’s recommended transmission-fluid type and service intervals; towing heavy loads can accelerate wear and heat buildup.
- Ask the dealer about software calibration updates, which can address shifting behavior without needing a full component replacement.
- If the problem persists and the vehicle is under warranty or an extended warranty program, pursue diagnostic work promptly to determine whether a repair, rebuild, or replacement is warranted.
Conclusion: Engaging early with a dealership, keeping up with maintenance, and reviewing recall/TSB history can help owners obtain appropriate remedies and possibly reduce out-of-pocket costs.
Model-year guidance and buyer tips
For prospective buyers and current owners, understanding which transmissions were used in specific Ram models can help set expectations about reliability and potential service needs.
- Be cautious with older Ram trucks that relied on five- or six-speed automatics, particularly if they show shifting irregularities or overheating signs during heavy towing.
- When shopping for a used Ram, request records showing any transmission work, software updates, or recall completions, and consider a pre-purchase inspection focused on the drivetrain.
- Consider newer Ram models with the latest eight-speed transmissions and updated calibration strategies, which have generally improved efficiency and driveability.
Conclusion: Knowledge of the specific transmission type and model-year history helps buyers evaluate risk and plan maintenance or potential repairs accordingly.
Summary
Ram truck transmission issues have been more prominent in certain generations and with particular transmission families. The five- and six-speed automatics associated with older Ram models have shown shifting, durability, and torque-converter concerns, while the newer eight-speed transmissions generally deliver improved performance but have had their own calibration and shudder-related reports in some early deployments. Overall, transmission reliability is not uniform across the lineup, and proactive maintenance, timely software updates, and attention to recalls/TSBs play a crucial role in mitigating problems. For buyers or owners, the key is to identify the exact transmission in the vehicle, review its service history, and stay informed about any manufacturer-issued fixes.
