What does the P0733 code mean?
The P0733 code is a diagnostic trouble code (DTC) that indicates that your vehicle’s transmission is slipping. Specifically, it means that the third gear ratio is incorrect. This can cause your vehicle to shift poorly, lose power, and even stall while driving. If left untreated, this issue could cause serious damage to your transmission, resulting in costly repairs.
This mostly reflects in highway driving as it can manifest in the form of poor acceleration and performance while stepping on the throttle right after a gear shift. The vehicle may simply not act the way you are used to, and that leads to safety hazards, which is why it’s so important to deal with the code right away.
What causes the P0733 code?
There are many reasons that could potentially be behind the code P0733 and we think it’s crucial for you to know a bit more about these. This way you can make sure that the code won’t affect your car for the worse, so here’s our list of the most common culprits behind the code:
Over time, the clutches in your transmission can wear out, causing slippage and incorrect gear ratios. This is a common cause of the P0733 code.
Low transmission fluid
If your transmission fluid is low, it can cause the transmission to slip and lead to incorrect gear ratios. This can trigger the P0733 code.
Faulty shift solenoid
The shift solenoid is responsible for controlling the flow of transmission fluid in your vehicle’s transmission. If it’s faulty, it can cause incorrect gear ratios and trigger the P0733 code.
If there’s a problem with the wiring that connects your vehicle’s transmission to the onboard computer, it can cause the P0733 code to appear.
Which car models does the P0733 code affect the most?
The P0733 code can appear in a range of car models, but it’s most common in vehicles with automatic transmissions. Some of the car models that are most commonly affected by this issue include:
- Chrysler PT Cruiser: The 2001 to 2010 PT Cruiser models have experienced quite a bit of issue with the transmission system’s components that affected the code P0733 to be manifested.
- Audi A4: Transmission slipping is the main cause of the code P0733 appearing in some older Audi A4 models.
- BMW 7 Series: The E65 BMW 7 Series is often reported to be affected by the code P0733 due to frequent transmission fluid leaks and issues with the gearbox that led to rough shifts.
How to diagnose the P0733 code
Diagnosing the P0733 code can be tricky, but it’s important to identify the root cause of the issue. Here are the steps you can follow to diagnose the issue:
Check the transmission fluid
The first step is to check the transmission fluid level and condition. Low fluid levels or dirty fluid can cause the transmission to slip and lead to incorrect gear ratios.
Use a diagnostic scanner
A diagnostic scanner can help you identify the specific problem that’s causing the P0733 code to appear. This tool can read the code and provide additional information about the issue.
Inspect the clutches
If the transmission fluid is at the proper level and the diagnostic scanner doesn’t identify any issues, the next step is to inspect the clutches. Worn clutches can cause the P0733 code to appear.
Test the shift solenoid
If the clutches appear to be in good condition, the next step is to test the shift solenoid. This involves measuring the resistance of the solenoid and checking for proper function.
How to fix the P0733 code
Once you’ve identified the root cause of the P0733 code, you can take steps to fix the issue. Here are some potential fixes based on what you’ve found through the diagnostic phase and figuring out the cause of the problem:
Replace worn clutches
If the clutches are worn, they will need to be replaced. This can be a costly repair, but it’s essential for fixing the issue.
Add transmission fluid
If the transmission fluid level is low, adding more fluid can help fix the problem. Be sure to use the type of fluid recommended by your vehicle’s manufacturer.
Replace faulty shift solenoid
If the shift solenoid is faulty, it will need to be replaced. This is a relatively simple repair that can be done by a professional mechanic.
Check the wiring and connections
If there’s a problem with the wiring, it will need to be repaired or replaced. This is a complex repair that should be done by a professional mechanic.
How to prevent the P0733 code
To prevent the P0733 code from appearing in the first place, it’s important to take good care of your vehicle’s transmission. Here are some tips:
- Regular maintenance accordingly to the manufacturer’s specifications
- Transmission fluid and filter changes
- Avoiding sudden stops or harsh acceleration that may leave a mark on the transmission
- Taking your car to a mechanic regularly for transmission system inspections
Regular inspections by a professional mechanic can help identify potential issues before they become major problems. so you should follow a servicing schedule and do some of your own checkups to avoid having to deal with this code.
Ultimately, we can only say that the code P0733 can be pretty bad, but seeing the code on a scanner device doesn’t come close to experiencing transmission slips while driving. We want to help you avoid such a scenario at all costs, so we hope it won’t be a problem for you after going through our guide.
Make sure to pay attention to properly servicing the transmission system’s components to make your car last longer and avoid having to deal with the code.
Can I still drive my vehicle if I get the P0733 code?
While it is possible to continue driving your vehicle if you get the P0733 code, it is not recommended. Continuing to drive your vehicle with a faulty transmission can cause further damage and lead to more expensive repairs down the line.
How can I fix the P0733 code?
The best way to fix the P0733 code is to have your vehicle diagnosed by a qualified mechanic. The root cause of the issue may be a faulty solenoid or valve body, low transmission fluid levels, or a damaged torque converter. Once the underlying issue has been identified, the mechanic can perform any necessary repairs to get your vehicle back in working order.
How much will it cost to fix the P0733 code?
The cost of repairing the P0733 code will depend on the underlying cause of the issue and any necessary repairs. In some cases, simply replacing a faulty solenoid or valve body may be enough to fix the issue. However, more extensive repairs such as replacing a damaged torque converter can be more expensive.
