Does Dodge Rams have transmission problems?
Yes—some Dodge Ram pickups have had transmission problems, but reliability varies by model year and configuration. Modern Rams use newer 8-speed automatics and benefit from recalls and updates, though issues can still occur.
Historical context and model-year variations
Ram trucks have transitioned through several generations of automatic transmissions. Early generations relied on older four- to six-speed units that earned mixed reliability marks, while recent models have moved to modern eight-speed designs from suppliers like ZF. Each generation brought its own set of potential issues, and the likelihood of problems often correlates with age, mileage, heavy use (such as towing), and maintenance history.
Modern transmissions and reliability
In more recent years, Ram (the truck lineup under Stellantis) shifted toward updated eight-speed automatics and improved electronic control systems. This shift generally improved reliability and shift quality, though individual vehicles can still experience faults related to software, sensors, or cooling systems. Recalls and dealer service updates have addressed many common symptoms across model years.
Common problems by generation
Owners and watchdogs have documented a range of transmission concerns across Ram generations. The issues are not universal, but the following summarizes commonly reported problems by generation and era.
- Older Ram models (1990s–early 2000s) with 46RE/47RE/48RE and early 545RFE transmissions were often cited for torque-converter problems, harsh or shuddering shifts, slipping, and overheating in high-mileage applications.
- Mid-2000s to early-2010s Rams with the 545RFE or early 68RFE variants sometimes showed harsh or delayed shifts, rough transitions, and torque-converter shudder, with some cases improved by software updates or fluid changes.
- 2013–2018 heavy-duty Rams (2500/3500) equipped with the 68RFE automatic reported torque-converter faults, slipping, overheating, and erratic shifting under heavy loads; some updates and recalls were issued to address these symptoms.
- 2014–present Rams with modern eight-speed automatics (ZF 8HP family) generally perform well, but a subset of owners reported rough shifts, delayed engagement, or transmission electronics faults that were often resolved by software updates or recall work.
Concluding overview: Transmission problems have been notable in certain generations, but newer Ram trucks have benefited from advanced transmissions and improved control software. With proper maintenance and timely recall/service work, many Rams provide reliable long-term service.
Symptoms to watch for and how to test
When evaluating a Ram or diagnosing one you own, look for specific signs that may indicate transmission trouble. The following symptoms are commonly reported and warrant attention from a technician.
- Delayed or rough shifts, especially when moving between gears or under load
- Slipping gears or loss of drive, particularly at highway speeds
- Shuddering or surging during acceleration or deceleration
- Harsh engagement or a noticeable clunk when selecting Drive or Reverse
- Warning lights (transmission fault or check engine) or erratic shifting behavior
Concluding note: If you notice any of these symptoms, have the vehicle inspected promptly. Transmission work can be costly, and early diagnosis improves the odds of a successful repair.
What to check when buying or owning a Ram
Before purchasing a Ram or if you currently own one, use these checks to minimize risk and identify signs of transmission trouble early.
- Review the full service history, focusing on transmission fluid changes, pan drops, and any software updates or recalls addressed by the dealer.
- Check the VIN against NHTSA and Stellantis recall databases to confirm whether any transmission-related recalls have been completed or are outstanding.
- Test-drive to reproduce symptoms in a controlled setting (cold start, smooth acceleration, and under load). Note any delays, shudder, or slipping.
- Have a qualified mechanic inspect the transmission fluid condition (color, scent, particulates) and verify proper fluid level and type (Chrysler ATF+4 is common for many Ram transmissions).
- Assess cooling system health, as transmission overheating can contribute to failures, especially in towing or hot climates.
Concluding guidance: While not every Ram will have transmission problems, a cautious approach—verifying recalls, maintenance history, and conducting a thorough pre-purchase inspection—significantly reduces the risk of surprises down the road.
Summary
Transmission reliability in Dodge Ram trucks is a nuanced topic. Some older generations experienced notable issues with torque converters, harsh or slipping shifts, and reliability concerns in 46RE/47RE/48RE and early 545RFE/68RFE units. Modern Ram trucks use updated eight-speed automatics (ZF 8HP family) that generally offer improved reliability, with most problems resolved through software updates and dealer servicing. Buyers and owners should prioritize complete service histories, recall status, and professional inspections, especially for high-mileage or tow-heavy use. Overall, Ram transmissions can be dependable, but diligence matters to avoid or mitigate problems.
