What is the transmission problem with the ProMaster?

The transmission problem most commonly reported for the ProMaster is automatic transmission slipping, harsh or delayed shifting, and, in some cases, failure to engage. These issues have appeared across multiple model years and configurations, leading to recalls and service advisories from Stellantis (the parent company of Ram) and related service bulletins. This article outlines what owners are experiencing, possible causes, and steps you can take.

In more detail, drivers have described problems ranging from intermittent gear slipping and shuddering during takeoff to extended hesitation before the vehicle moves or shifts into higher gears. Some cases escalate to the point of the transmission not engaging at all or requiring costly repairs. The situation varies by model year, drivetrain, and maintenance history, and affected vehicles may be covered by recalls or software updates rather than a uniform defect across all ProMasters.

What owners are reporting

The following symptoms are commonly mentioned in owner reports and service notes. They help distinguish typical wear from broader transmission concerns.

• Slipping between gears or trouble maintaining steady acceleration


• Harsh, jerky, or delayed shifting, especially at lower speeds or when cold


• Delayed engagement when selecting Drive or Reverse from Park/Neutral


• Unusual noises, shuddering, or grinding during gear changes


• Warning lights or fault codes related to transmission control

These symptoms do not always indicate a fatal failure—many can be related to software updates, fluid condition, or sensor calibration—but they warrant prompt inspection to prevent further damage.

Causes and contributing factors

Service data and owner reports point to a mix of electronic, mechanical, and maintenance-related factors that can contribute to transmission issues in ProMasters.

• Electronic control software and calibration that governs shift timing and torque management


• Torque converter or clutch-pack wear in automatic configurations


• Transmission fluid quality and level, as well as cooling system performance


• Valve body or solenoid-related faults that affect hydraulic control

Because the ProMaster uses a family of transmissions that can vary by model year and drivetrain, the exact responsible component can differ from one vehicle to another. A diagnostic scan combined with fluid inspection often helps pinpoint the root cause.

What to do if you own a ProMaster

If you own a ProMaster and notice transmission-related symptoms, follow these practical steps to protect your vehicle and budget.

• Schedule a diagnostic check with an authorized service center as soon as you notice symptoms


• Ask for a transmission control module (TCM) calibration or software update if recommended by the tech


• Have the transmission fluid type, level, and condition evaluated and replaced if specified by maintenance guidelines


• Inspect cooling lines and the transmission cooler for leaks or blockages that can cause overheating


• Document symptoms, mileage, and driving conditions to help technicians reproduce the issue

Early action can prevent more extensive damage and may qualify the vehicle for any applicable recalls or service campaigns.

Recalls, service bulletins, and how to verify status

Recalls and Technical Service Bulletins (TSBs) related to transmissions are issued periodically. To determine if a specific ProMaster is affected, use the VIN and check official sources, and discuss with your dealer or a qualified shop.

• Check active recalls for your VIN on the NHTSA website or the manufacturer’s recall portal


• Ask the dealer for any applicable TSBs that cover transmission software updates or hardware diagnostics


• Request a comprehensive diagnostic report if the vehicle has recurring symptoms, even if a single fault code is not persistent


• Follow recommended service intervals for transmission fluid and cooling system maintenance

Staying current with recalls and service advisories can reduce the risk of unexpected failures and help ensure your ProMaster remains reliable for work and daily use.

Summary

Transmission issues for the Ram ProMaster most often present as slipping, harsh or delayed shifting, and occasional failure to engage. Causes can be software-related, mechanical wear, fluid or cooling problems, or valve/solenoid faults. If you notice symptoms, prompt diagnostic testing—ideally under warranty or a recall/service bulletin—can prevent further damage. Always verify recall status by VIN and work with an authorized technician to determine the appropriate remedy.

Do ProMasters have transmission problems?

Yes, Ram ProMasters have documented transmission problems, including a history of failures often linked to the vehicle's front-wheel-drive design and potentially undersized transmission. Common issues reported by owners include delayed or inconsistent shifting, fluid leaks, and even catastrophic failures like detached transmissions due to problems with mounts and bolts. Some older models have also had recalls related to transmission safety. 
Common transmission issues

• Shifting problems: Inconsistent gear shifts, hesitations, and the transmission getting stuck in neutral have been reported. 
• Fluid leaks: Transmission fluid leaks are a known problem. 
• Mounting and bolt failures: A significant failure point is the transmission mount and associated bolts, which can break or shear off, leading to the transmission detaching from the vehicle. This issue is particularly noted in earlier models, and while revised parts are available, the potential for failure remains a concern. 
• Other warning signs: Owners also report warning lights, strange noises or smells, and grinding sounds when shifting. 

Causes and contributing factors

• Front-wheel-drive (FWD) design: The FWD configuration can make transmissions more susceptible to failure and more expensive to repair when they do fail. 
• Underlying components: The use of an older, potentially undersized transmission has been cited as a reason for high failure rates. 
• Electrical faults: Issues like corroded electrical harness connectors can lead to loss of communication with the transmission control module, causing the transmission to shift into neutral unexpectedly. 

What to do

• Check for recalls: Ensure any recalls, especially related to the transmission, have been addressed. 
• Be vigilant about maintenance: Regular transmission fluid checks and changes can help prevent some issues. 
• Be aware of potential failures: If you own or are considering buying a ProMaster, be aware of the potential for mount and bolt failure and factor in the cost and time for repairs or proactive reinforcement. 

Is there a recall on the Ram ProMaster transmission?

2019-2021 Ram ProMasters have been recalled for a transmission issue that can cause a potential rollaway problem. Over 50 million vehicles in the U.S. have unrepaired safety recalls, according to the National Safety Council.

Which RAM ProMaster to avoid?

You should be wary of Ram ProMaster models from 2014-2016, 2018, and 2021 and older, as these years are more frequently associated with transmission issues. However, some 2022 models and newer have also received negative reviews for various mechanical and electrical problems. It is always best to research specific model years, especially those with major redesigns, and to prioritize a comprehensive pre-purchase inspection and service history check. 
Years to be cautious about

• 2014–2016: These early years have a higher number of reported transmission complaints. 
• 2018: Some owners reported issues with the transmission, serpentine belt, door hinges, and leaks. 
• 2021 and older: These model years are often cited as having potential transmission issues. 

Other concerns

• 2022: Despite transmission updates, some 2022 models have been associated with problems like starter issues and problems with the e-brake. 
• 2024: While some 2024 models are problem-free, some consumer reviews mention recurring issues like serpentine belt problems, door hinge failures, and potential leaks. 
• ProMaster City: This smaller model has also been reported to have issues such as oil consumption problems in some models, and a small gas tank. 

What to do when buying

• Perform a pre-purchase inspection: Get a professional inspection of any used vehicle you are considering, especially for commercial vans.
• Request maintenance records: Ask for the vehicle's service history to ensure it has been properly maintained.
• Test all electronics: Make sure the windows, lights, and all electronic features work properly before buying.
