When the level drops too low or becomes dirty and degraded, your Ram may start slipping, hesitating, overheating, or producing odd noises. Whether you drive a newer Ram 1500 with a sealed transmission or an older model equipped with a dipstick, understanding how to verify fluid level and condition is essential.
This guide walks you through the steps, signs to watch for, and what to do if you find a problem.
How to Check Transmission Fluid Level Ram 1500
To check the transmission fluid level on a Ram 1500, warm up the truck, park it on level ground, keep the engine running, and use the transmission dipstick, if equipped, to measure fluid within the “HOT” range.
However, newer Ram 1500 models with sealed transmissions must be checked from the fill/check plug underneath the vehicle at a specific temperature, typically requiring a scan tool and proper equipment.
1. Warm the Truck Up
Transmission fluid expands as it heats. Drive for at least 10–15 minutes to bring the fluid to normal operating temperature. Park the truck on a level surface to get an accurate reading.
2. Keep the Engine Running
Most Ram models require the engine to be running and the transmission in “Park” or “Neutral” while you check the fluid.
3. Open the Hood and Locate the Dipstick
Look for a brightly colored handle marked “Transmission.” On many Ram models, it is located near the back of the engine bay.
4. Remove and Clean the Dipstick
Pull the dipstick out, wipe it clean using a lint-free cloth, and reinsert it fully.

5. Pull It Out Again and Read the Level
Remove the dipstick a second time and look at the fluid level. It should fall within the “HOT” range markings when the transmission is fully warmed up.
6. Check the Fluid Condition
Healthy transmission fluid should appear:
- Bright red or pink
- Semi-transparent
- Smooth in texture
If it appears dark brown, has particles, smells burnt, or looks milky (a sign of coolant contamination), the fluid may need to be changed immediately.
7. Add Fluid if Needed
If the fluid is low, add only the recommended ATF type for your specific Ram 1500. Add small amounts at a time through the dipstick tube and recheck until you reach the proper level. Do not overfill, as this can damage seals and cause foaming.
Why Checking Transmission Fluid Matters
The transmission in your Ram 1500 is a complex hydraulic system that depends on clean, properly-filled fluid to operate correctly. Low or contaminated fluid can cause erratic shifting, delayed engagement, shuddering, or overheating.
If not corrected early, these issues can lead to internal damage, burned clutches, or a complete transmission failure. Regular checks help your truck last longer, drive smoother, and avoid avoidable repair bills.

Do All Ram 1500 Models Have a Transmission Dipstick?
Your method for checking transmission fluid depends on the model year and specific transmission. Older Ram 1500 models, especially those from the early 2000s, typically come with a traditional transmission dipstick. However, most newer Ram 1500 trucks (2013 and newer) use a sealed transmission.
These sealed units do not have a standard dipstick under the hood. Instead, fluid inspection requires accessing the fill or check port underneath the truck, usually performed while the transmission is at a specific temperature. If you have a sealed unit, it is strongly recommended that the check be done by a certified technician unless you have the correct tools, scanner, and equipment.
How to Check Transmission Fluid in a Sealed Ram 1500
Many 8-speed and 6-speed Ram transmissions are sealed and require the following:
- A scan tool to verify transmission temperature
- Access to the transmission check plug
- A level lift or jack stands
- Proper safety equipment
The check plug is located on the transmission pan. The transmission must be at the correct temperature (usually around 85–120°F, depending on the model). With the plug removed, a small amount of fluid should drip out if it is at the correct level. Too much flow indicates overfill; no flow indicates low fluid.
Because this method requires precise steps and tools, most owners choose to have a shop perform the check.

Signs Your Ram 1500 Transmission Fluid Is Low
If you notice any of the following, it may be time to check your transmission fluid level:
- Slow, delayed, or harsh shifting
- Transmission slipping at high RPM
- Shuddering or vibration during acceleration
- Grinding or whining noises
- Overheating or a burning smell
- Visible leaks under the truck
Addressing low fluid early can prevent catastrophic failure.
When Should You Check Your Ram 1500 Transmission Fluid?
A good rule is to check the fluid at every oil change. If you tow heavy loads, drive in extreme heat, or off-road frequently, check it more often. Even sealed transmissions benefit from periodic inspection during scheduled service intervals.
FAQs
Does a Ram 1500 have a transmission dipstick?
Most older Ram 1500 models came with a transmission dipstick, but many newer models, especially those with 6-speed and 8-speed sealed transmissions, do not. If you have a newer Ram, the transmission is likely sealed and requires checking fluid from the fill/check port underneath the truck instead of a dipstick under the hood.
Do I check my transmission fluid while the engine is running?
Yes. On Ram 1500 models equipped with a dipstick, you should check the transmission fluid with the engine running, the truck warmed up to operating temperature, and the transmission set to “Park” or “Neutral.” This ensures an accurate reading because transmission fluid expands when hot and circulates through the system while the engine runs.
How to check transmission fluid level when there is no dipstick?
For sealed Ram transmissions without a dipstick, the fluid is checked through a fill/check plug located on the transmission pan. The truck must be lifted level, the transmission must be brought to a specific temperature (verified with a scan tool), and a small amount of fluid should drip from the check plug if the level is correct. If nothing comes out, the fluid is low; if too much pours out, it’s overfilled.
Where to add transmission fluid to a Dodge Ram 1500?
If your Ram 1500 has a transmission dipstick, you add fluid through the same tube where the dipstick sits, pour in small amounts at a time, and recheck the level. If your truck has a sealed transmission with no dipstick, fluid must be added through the fill port underneath the vehicle, which typically requires a fluid pump and should be done during the temperature-based level check.
What years to avoid for the 5.7 Hemi Ram 1500?
The 2009–2012 Ram 1500 models with the 5.7 Hemi are commonly noted as years to avoid due to significant issues like cam and lifter failures, dropped valve seats, and early MDS (Multi-Displacement System) problems. Later model years saw improvements in design, reliability, and overall engine durability.
