By Ezra Lane If you're encountering the P0735 Nissan code, this indicates an issue with gear 5 showing an incorrect ratio, highlighting potential transmission problems. Key causes often include low or dirty transmission fluid, faulty shift solenoids, or worn gear components. You'll likely notice symptoms such as RPM fluctuations, difficulty accelerating, and the activation of the check engine light. It's crucial to use an OBD-II scanner for diagnosis, check the transmission fluid, and inspect the shift solenoids. Addressing this promptly avoids further damage and ensures safer driving. A deeper exploration into this could reveal additional preventive measures and insights into maintaining your vehicle's transmission health.
P0735 Nissan Code Meaning
The P0735 Nissan code indicates a problem with shifting into fifth gear due to an incorrect gear ratio detected by the transmission control module.
Possible causes include worn gear components, transmission fluid issues, or faulty shift solenoids, requiring a thorough diagnostic to prevent further damage.
Error Code P0735 Symptoms
When your Nissan has trouble getting into 5th gear, you might notice some warning signs that affect how your car runs and uses fuel.
Here are some things to look out for:
- Engine Stops: The car might stall when shifting because the transmission isn't working right.
- Odd Engine Speeds: The RPMs may jump around, especially when moving to higher gears. This means the gears aren't matching up well.
- Slow to Speed Up: If your car isn't speeding up like it should, especially at high speeds, the transmission might be slipping or not hitting fifth gear.
- Check Engine Light On: If this light comes on, there could be a problem with the transmission, like the P0735 code.
These issues can make your car run louder and use more fuel.
It's a good idea to check things out and fix any problems.
Causes of Nissan P0735 Fault Code
When your Nissan shows a P0735 code, it often means there's a problem with shifting into 5th gear. The issue usually comes from the transmission system.
Here are some possible reasons:
- Low transmission fluid: Not enough fluid can make gear shifting hard because there's not enough pressure.
- Dirty transmission fluid: If the fluid is dirty, it can't help gears move smoothly.
- Bad shift solenoids: These parts help control the fluid. If they're not working, getting into 5th gear can be tough.
- Worn or damaged gears: Gears that are worn out or damaged can mess up how they work together.
Knowing these causes helps you fix the problem correctly. You might need to add or change the fluid, fix solenoids, or do big repairs on the transmission.
Tools Needed to Diagnose
To figure out the P0735 Nissan code, you need a few key tools. Make sure you have these on hand:
- OBD-II Scanner: Use this to read the P0735 code and see live data from your car's transmission control module.
- Multimeter: This helps check if the shift solenoids are working and measures electrical resistance. It can reveal electrical problems causing the code.
- Dipstick or Fluid Level Gauge: Check how much transmission fluid you have and its condition. Low or dirty fluid might cause issues.
- Torque Wrench: Useful for removing or adjusting parts like the transmission pan. It helps you tighten things correctly.
Also, keep a repair manual for your Nissan model. This will give you diagrams and details, making the process easier.
Having these tools helps in diagnosing the problem and preparing for any needed repairs.
How to Fix P0735 Nissan Error Code – Step by Step
Step 1:
Begin by checking the transmission fluid level and condition. If the fluid is low or appears dirty, top it off or change it, as this might resolve the P0735 Nissan error code.
Step 2:
Inspect the wiring harness and connectors thoroughly. Look for any visible damage or corrosion that could impair the electrical circuitry. Repair or replace any damaged parts to ensure proper functionality.
Step 3:
Test the shift solenoids. These components are essential for managing gear transitions. If they aren't functioning correctly, the transmission won't shift into 5th gear properly. Replace any faulty solenoids if they're identified as the root cause of the error.
Step 4:
Examine the transmission hydraulic control circuit for any leaks or mechanical issues that could affect gear shifting. Addressing these problems can help restore proper transmission operation.
Step 5:
If the P0735 code persists after completing these steps, consult a professional mechanic. They can provide a more in-depth diagnostic assessment and carry out repairs based on manufacturer guidelines to ensure your vehicle is back to optimal performance.
Common Diagnosis Mistakes
Many people skip checking the transmission fluid when they see the P0735 Nissan error code. This mistake can lead to wasted time and money.
Here are some things to keep in mind:
- Check Fluid Quality: Look at the fluid's color and clarity, not just the amount. Bad fluid can mess up how the transmission shifts.
- Mechanical vs. Electrical: Before thinking it's an electrical problem, look at the mechanical parts. A broken part can seem like an electrical issue.
- Wiring and Connections: Check all the wires and connectors. Sometimes, what looks like a transmission problem is really a wiring issue.
- Follow Manufacturer's Steps: Use the steps given by the carmaker. Skipping them can lead to wrong guesses and missed simple fixes.
P0735 Nissan Repair Cost
Fixing a P0735 error code on your Nissan can cost different amounts.
First, diagnosing the problem may cost between $75 and $150, depending on where you live.
If you need to fix the issue, costs can vary. Changing the transmission fluid might cost around $200.
If it involves more complex parts like shift solenoids or mechanical issues in the transmission, costs can be higher. These repairs might exceed $1,000 and sometimes reach up to $1,500 or more.
Related Error Codes on Nissan
If you see a P0735 error code on your Nissan, you might also come across codes like P0730, P0731, P0732, and P0733. These codes all relate to problems with gear ratios, pointing to potential issues in your car's transmission system.
Here's what each code means:
| Code | Description | What It Might Mean |
|---|---|---|
| P0730 | Wrong Gear Ratio | General transmission issue |
| P0731 | 1st Gear Wrong Ratio | Problem with first gear |
| P0732 | 2nd Gear Wrong Ratio | Problem with second gear |
| P0733 | 3rd Gear Wrong Ratio | Problem with third gear |
To fix these issues, you need to look into the transmission fluid, solenoids, or mechanical parts. Check whether the problem is electrical, hydraulic, or mechanical. Addressing all these codes together can help prevent more damage and expensive repairs. Clearing the codes won't solve the problem; it's important to find and fix the issue to keep your Nissan running well.

People Also Ask
Does Weather Affect the Likelihood of Encountering the P0735 Error?
Yes, weather can affect car problems like the P0735 error. When it's very hot or cold, the fluid in your car can change, making it hard to shift gears. Wet weather can also mess with electrical parts, causing more problems.
Can Aftermarket Modifications Trigger a P0735 Code?
Yes, adding aftermarket parts to your car, especially for the transmission or powertrain, can make it more likely to show a P0735 code. This happens because the new parts might change how the car's computer sees things compared to the original factory settings.
How Does P0735 Impact Fuel Efficiency?
If your car has the P0735 code, it won't shift into overdrive. This means the engine works harder and uses more fuel, especially on highways. So, you'll get fewer miles per gallon, making your car less fuel efficient.
Are Certain Nissan Models More Prone to the P0735 Code?
Yes, some Nissan cars like older Altimas, Maximas, Pathfinders, and Sentras can have more problems with the P0735 code. This happens because of how the cars are taken care of and the quality of the transmission fluid used in them.
Does Resolving P0735 Improve Vehicle Resale Value?
Fixing the P0735 error can make your car worth more when you sell it. It shows that the transmission is in good shape, making your car more appealing to buyers. This can help you sell it faster and for a better price.
