How to Fix Hard Shifting
Experiencing hard shifting in your 2018 Dodge Ram can be frustrating. While the provided data doesn't explicitly detail hard shifting causes, it does bring up related issues and general maintenance concerns that could indirectly influence transmission performance. One owner highlighted the importance of preventative maintenance, saying, "Well guys I just picked up my first Ram! went for a 2018 1500 SLT loving it only 89,500 miles no ticks yet… praying😂😂 got some big plans for it!!!" (source). This underscores the need to stay vigilant about your truck's overall health.
Symptoms
Given the data available, which focuses on other potential problems, connecting directly reported symptoms to hard shifting is difficult. However, owners frequently discuss general operational issues that could contribute or be perceived as related. For instance, a reduction in overall engine performance might manifest as rougher gear changes.
Owners mention seemingly unrelated electrical issues that could potentially impact the electronic control of the transmission. The report of a 115V outlet randomly shutting off could indicate a broader electrical system problem. One owner experienced this issue, stating, "Went tailgating last night after a quick test run with my pellet grill plugged into the 115 outlet on the dash of my 2018 1500. The startup process (which draws the most power) went perfectly fine, started climbing into the 270 range no problem, then shut off." (source). While not directly related to shifting, this shows the type of unexpected malfunctions owners face.
Another area of concern, though not directly linked to hard shifting in the provided data, is engine maintenance and potential lifter issues. A properly functioning engine is essential for smooth transmission operation. An owner seeking advice on this said, "Hemi 5.7L Maintenance Watchouts: What are the non-negotiable inspection points? I've heard the usual noise about lifters/MDS—how big of a problem is it really on the 2018?" (source). This suggests that paying attention to engine health is critical.
While seemingly unrelated, the mention of a "musty smell" could indicate moisture intrusion that, in extreme cases, might affect electrical connections linked to the transmission control system. Although the link is tenuous, it's an example of how various issues can indirectly influence vehicle performance. The presence of a musty smell could point to other underlying problems needing attention.
Most Likely Cause
Given the limited data, pinpointing a single most likely cause for hard shifting in your 2018 Dodge Ram is challenging. However, considering that owners are concerned about general maintenance, and the interplay of electronics within the modern vehicle, it’s plausible that underlying electrical issues could potentially affect the transmission's performance. Although no direct connection can be made between the provided data and hard shifting issues, the discussions around electrical faults suggest paying attention to electrical problems if they exist.
How to Diagnose
While no owner provided a direct diagnostic procedure for hard shifting, a general approach involves assessing your truck for any active warning lights. Use an OBD-II scanner to read trouble codes. Note down any codes related to the transmission, engine, or electrical system.
Visually inspect the transmission fluid level and condition. Low or dirty fluid can contribute to shifting problems. Check for leaks around the transmission pan and lines.
Next, check the health of your battery and charging system. A weak battery can cause erratic electrical behavior, potentially affecting the transmission control module. Use a multimeter to test the battery voltage and alternator output.
Lastly, if you have access to a more advanced scan tool, monitor live data from the transmission control module while driving. Observe parameters such as transmission temperature, gear selection, and solenoid activity. This data can provide valuable clues about the cause of the hard shifting.
Step-by-Step Fix
Because we are limited to the provided data, a direct step-by-step fix isn't possible. However, based on the general concerns raised by owners, consider these steps.
- Address any identified fault codes: Using the OBD-II scanner, research each fault code to determine the appropriate repair procedure.
- Check and correct transmission fluid level: If the fluid is low, top it off with the correct type of transmission fluid. Refer to your owner's manual for specifications.
- Replace dirty or contaminated transmission fluid: If the fluid appears dark, smells burnt, or contains debris, perform a transmission fluid and filter change.
- Inspect and clean electrical connections: Check the wiring harness and connectors going to the transmission control module. Look for signs of corrosion or damage. Clean the connections with electrical contact cleaner.
- Check battery and charging system: As mentioned, a weak battery can cause a variety of problems. As one owner shared, "Well guys I just picked up my first Ram! went for a 2018 1500 SLT loving it only 89,500 miles no ticks yet… praying😂😂 got some big plans for it!!!" (source). This emphasis on preventative maintenance includes ensuring your battery is healthy.
- Address any other identified engine or electrical problems: Rectify any underlying issues, such as the 115V outlet problem or potential lifter problems, as these can indirectly affect transmission performance.
- Test drive the vehicle: After performing any repairs, test drive your 2018 Dodge Ram to see if the hard shifting has been resolved.
Parts and Tools Needed
Given the limited data, providing a precise parts list is difficult. However, a general list includes:
- OBD-II scanner
- Multimeter
- Transmission fluid (check your owner's manual for the correct type)
- Transmission filter (if performing a fluid and filter change)
- Electrical contact cleaner
- Basic hand tools (sockets, wrenches, screwdrivers)
Real Owner Costs
Based on the limited data, direct costs related to hard shifting repairs for the 2018 Dodge Ram are unavailable. However, an owner mentioned a key replacement costing "$500 per key" (source. This highlights the potential expense of dealing with modern vehicle systems and can inform expectations regarding repair costs. Therefore, for transmission-related repairs, expect a wide range of costs depending on the severity and the chosen repair method (DIY vs. professional).
Prevention
Preventing hard shifting in your 2018 Dodge Ram involves adhering to a strict maintenance schedule. Regularly check and maintain your transmission fluid level, and change the fluid and filter according to the manufacturer's recommendations.
Address any engine or electrical problems promptly, as these can indirectly impact transmission performance. Perform regular inspections of your truck's electrical system, looking for signs of corrosion or damage. As one owner stated "Hemi 5.7L Maintenance Watchouts: What are the non-negotiable inspection points? I've heard the usual noise about lifters/MDS—how big of a problem is it really on the 2018?" (source, highlighting the need to stay ahead of possible issues.
Avoid aggressive driving habits, such as hard acceleration and sudden braking, as these can put undue stress on the transmission. Ensure the truck is not overloaded, since carrying excessive weight can also cause shifting problems.
