Nissan Altima shifts into gear but won’t move? Whether an automatic car or equipped with a stick shift for those who prefer a manual transmission, offers a unique driving experience.
The transmission system in these cars, especially the continuously variable transmission (CVT), is designed for smooth shifting gears and excellent fuel economy.
Understanding Why Nissan Altima Shifts Into Gear But Won’t Move
Nissan Altima models, especially those equipped with an automatic transmission or a continuously variable transmission (CVT), are known for their smooth shifting gears and fuel economy.
However, even the most fuel-efficient cars can run into transmission problems.
Manual vs. Automatic Transmission
- Manual Transmission: Requires a more engaged driving experience.
The clutch pedal must be pressed down to disengage the gears while the driver manually selects the appropriate gear using the stick shift.
Manual transmissions typically use gear oil rated at 75W-80 to 75W-90, depending on the manufacturer’s specifications.
- Automatic Transmission/CVT: Nissan Altima’s equipped with CVTs use a special type of transmission fluid, often referred to as NS-2 or NS-3 fluid, specific to Nissan vehicles.
This fluid is designed to reduce friction and wear within the continuously variable transmission, which does not use traditional gears but rather a belt and pulley system to provide a seamless range of gear ratios.
Common Causes Why Nissan Altima Shifts Into Gear But Won’t Move
Clutch and Gear System Complications
- Planetary Gears: In automatic transmissions, these gears can suffer from wear or damage, leading to issues with shifting, especially into reverse gear or higher gears.
The intricate design requires professional attention for repairs.
Transmission Fluid Problems
- The recommended interval for changing the transmission fluid in a Nissan Altima is typically every 30,000 to 60,000 miles.
However, this can vary based on driving conditions and the type of transmission fluid used. Dirty or low fluid can lead to increased friction and heat, causing the transmission to perform poorly or even fail.
Transmission Control Module (TCM) Failures
- The cost of replacing a faulty transmission control module can range from $900 to $1,000, including parts and labor.
This module’s proper functioning is crucial for interpreting electrical signals from the transmission’s sensors and executing gear shifts.
Nissan Altima Shifts Into Gear But Won’t Move : Clutch and Gear System Complications
- For manual transmissions, replacing a clutch pedal assembly might cost between $500 to $800, depending on labor rates and parts.
In automatic transmissions, repairing or replacing planetary gears can be significantly more expensive, potentially exceeding $2,000 for a complete overhaul.
Fuel System Faults
- Low Fuel Pump Pressure: Insufficient fuel pressure affects the engine’s performance, indirectly impacting the transmission system.
This can make the car struggle at higher speeds or when trying to engage higher gears.
- Fuel pressure regulators and pumps are critical for maintaining the engine’s performance, which indirectly affects the transmission.
A replacement fuel pump for a Nissan Altima can cost between $300 to $1,200, including parts and labor, depending on the model year and engine type.
Nissan Altima Shifts Into Gear But Won’t Move: Air and Fuel Delivery Issues
- A failing fuel pressure regulator means your car isn’t getting the right amount of fuel.
- Clogged fuel injectors block fuel flow, making the engine run rough.
- Weak fuel pumps can’t supply enough fuel, leading to poor performance.
- Dirty fuel filters restrict fuel from reaching the engine.
- If throttle bodies and air filters are dirty, your car won’t perform well.
- Damage to the air intake system can cause engine problems.
Exhaust System Problems:
- A damaged muffler can restrict exhaust flow, which can affect engine performance.
- Clogged catalytic converters prevent exhaust from exiting the engine, which can lead to reduced power.
- Any issues with the exhaust pipes can cause performance problems.
Engine Mechanical Issues:
- A damaged head gasket can lead to overheating and power loss.
- Problems with pistons, cylinder walls, or rings can reduce engine efficiency.
- Issues with valves or the timing chain can disrupt the engine’s operation.
Ignition System Faults:
- A faulty distributor can throw off the engine’s timing.
- Worn or damaged spark plugs can prevent the engine from starting or cause misfires.
- Bad ignition modules, wires, or coils can lead to poor engine performance.
Module and Sensor Failures:
- Problems with the car’s computer can affect the transmission’s ability to shift gears.
- If sensors fail, they can send incorrect signals that can cause various driveability issues.
- Issues with the transmission control module can lead to shifting problems.
Transmission Troubles:
- Clogged transmission filters can lead to shifting problems.
- A bad valve body or faulty shift solenoid can cause erratic shifting.
- Worn-out clutch parts in manual transmissions can make shifting difficult.
- Damaged gears can cause noise and shifting issues.
- Problems with hub sleeves can lead to difficulty in shifting gears.
- Low or contaminated transmission fluid can cause transmission failure.
- Lack of clutch fluid in manual transmissions can prevent shifting.
- Problems with the synchronizer ring can make it hard to shift into gear.
- Damaged or misaligned shifter cables can make it difficult to select gears.
Diagnosing Nissan Altima Shifts Into Gear But Won’t Move
Warning Signs and Symptoms
- A check engine light that comes on due to transmission issues might generate specific diagnostic trouble codes (DTCs) such as P0700 (Transmission Control System Malfunction) or P0730 (Incorrect Gear Ratio).
These codes can help pinpoint the issue more accurately.
Professional Diagnosis
- Diagnostic fees at a dealership or an independent mechanic can range from $75 to $150.
This initial cost is often applied toward the repair bill if you choose to have the work done at that facility.
Nissan Altima Shifts Into Gear But Won’t Move: Solutions and Repairs
DIY Fixes vs. Professional Repairs
- Changing your Nissan Altima’s transmission fluid at home might cost between $50 to $100 for the fluid and new filters, compared to $150 to $250 at a service center.
Understanding Repair Options
- Transmission Including Repairs: When considering repairs, it’s essential to understand that the transmission system might need a comprehensive check, including the planetary gears, dual clutch transmission, or the semi-automatic transmissions mechanism, depending on your Altima’s specific setup.
- A complete transmission replacement for a Nissan Altima can range from $1,800 to $3,500, significantly impacting your decision on whether to repair or replace the vehicle, especially if it’s older.
Preventative Measures and Maintenance Tips
- Regularly checking your transmission fluid level and condition can help catch issues early. For CVTs, using the correct type of fluid (NS-2 or NS-3) is crucial, as using the wrong fluid can cause damage and lead to costly repairs.
FAQs: Nissan Altima Shifts Into Gear But Won’t Move
How does the brake pedal affect my transmission?
Using the brake pedal smoothly and consistently helps manage your car’s speed without putting unnecessary strain on the transmission system, especially when downshifting or coming to a stop.
Can I improve my fuel economy by how I use my transmission?
Yes, by utilizing higher gears at appropriate times and avoiding aggressive acceleration, you can maintain a better fuel economy.
This is because the engine works more efficiently at steady, higher speeds without over-relying on the transmission to adjust the power.
What does the steering wheel have to do with the transmission?
While the steering wheel mainly controls the direction of your car, it also plays a part in how you use the transmission.
For example, when turning sharply, you might need to downshift to give your car more power.
Smooth steering and smart gear use can help prevent wear and tear on your transmission.
How can I prevent transmission failure when Nissan Altima Shifts Into Gear But Won’t Move
Regular maintenance is key. This includes checking your transmission fluid regularly and being mindful of how your car feels and sounds when you drive.
If something feels off, especially with how your car shifts gears or responds to the steering wheel, it’s time for a check-up.
