Using diesel fuel to clean transmissions is not recommended. While it may be an old trick to desludge engine oil, modern trans fluids already contain a fluid package with cleaners. Therefore, it is not necessary to add diesel fuel to the transmission for cleaning purposes.
There are alternative products available specifically designed for flushing transmissions, such as those from WYNN's, BG, and Sea Foam. These products can be purchased from auto dealers or parts stores and are a better option than using diesel fuel.
It is worth noting that some people have used diesel fuel in their fuel tanks to clean injectors, particularly in older vehicles with mechanical injection pumps and injectors. However, this practice is not recommended for newer systems, as it may void warranties and cause damage due to the high-pressure sensitivity of modern engines.
Additionally, it is important to avoid using water-based solutions or certain solvents, such as gasoline, diesel fuel, paint reducer, alcohol, and kerosene, when cleaning automatic transmission components like solenoids, friction plates, and bands, as they can cause damage and affect performance.
In conclusion, while using diesel fuel to clean transmissions may have been a traditional practice, it is not advisable due to the availability of specialized cleaning products and the potential risks associated with using diesel fuel in modern vehicles. It is always best to consult a professional or refer to the manufacturer's recommendations for safe and effective cleaning methods.

Trans fluid already has a fluid package that includes cleaners
While some people suggest using diesel fuel to clean a transmission, there are alternative methods and products that can be used to clean your transmission.
Transmission fluid, also known as "TRanny fluid", is a hydraulic fluid that already has a fluid package that includes cleaners. It is a mild detergent with significant amounts of detergents and additives that can clean injectors and sustain normal operation for up to 30,000 miles. However, it is important to note that this may not be suitable for newer systems and it is recommended to seek advice from a professional before proceeding.
There are also dedicated ATF cleaners available in the market, such as LIQUI MOLY ATF Cleaner, which can be added to your existing fluid to clean out any residue or deposits that have built up inside your transmission. These cleaners are especially useful for older vehicles that are more prone to transmission problems.
Another method is to use a transmission flush product, such as Seafoam's TRANS TUNE, which can be added to the transmission fluid before a transmission flush or fluid and filter change. This will help to clean the transmission valves and parts.
It is important to note that before attempting any cleaning or maintenance on your transmission, it is always recommended to consult a professional or refer to your vehicle's manufacturer recommendations.

Automatic transmission fluid (ATF) is a mild detergent and can clean injectors
It is not recommended to use diesel fuel to clean your transmission. This is an old trick to desludge engine oil, but it is not effective. Trans fluid already includes a fluid package with cleaners. If you want to flush your transmission, you should use products specifically designed for this purpose, such as those from WYNN's, BG, or Sea Foam.
Automatic Transmission Fluid (ATF), on the other hand, is a mild detergent and can be used to clean injectors. This technique is commonly used in older vehicles with mechanical injection pumps and injectors, such as the 1986 VW diesel with a Bosch system. The process involves filling the fuel filter with ATF during a change, which helps to clean the inside of the mechanical pumps and injectors. While this method may not be suitable for newer systems, some people suggest that filling the secondary filter housing with ATF could be beneficial.
One suggestion is to run your fuel tank down to about a quarter full and then add around two gallons of ATF. Run the vehicle for a few minutes to allow the ATF to reach the injectors, then turn it off and let the ATF soak overnight. The next day, the vehicle may sputter and smoke, but it should eventually run smoothly. However, it is important to note that adding ATF to your fuel tank may void your warranty, as it can affect fuel pressures and injector O-rings.
While ATF can provide some cleaning benefits, it is not necessary to let the injectors soak in it. Simply adding a small amount of ATF to your tank during a fill-up and running it through can help keep your injectors clean. This method is safer and less likely to cause any potential damage to your vehicle.
In conclusion, while diesel fuel should not be used for cleaning transmissions, ATF can be an effective and mild detergent for cleaning injectors, especially in older vehicles with mechanical injection systems. However, it is always recommended to consult a professional mechanic or refer to the manufacturer's guidelines before attempting any cleaning or maintenance procedures on your vehicle.

ATF is an old-school technique from the days of mechanical injection pumps
Using ATF (Automatic Transmission Fluid) to clean fuel injectors is an old-school technique that was common in the days of mechanical injection pumps and injectors. This method involves filling the fuel filter with ATF during a change, as ATF is a strong detergent that effectively cleans the inside of mechanical pumps and injectors. While this technique may still work for older vehicles, it is not recommended for newer systems, as it may void the warranty.
The use of ATF as a cleaning agent is based on its detergent properties, which can help remove sludge and deposits from fuel injectors. However, it is important to note that modern fuel injectors may not require such intensive cleaning methods, and there are now dedicated products available specifically designed for this purpose. These products include offerings from WYNN's, BG, and Sea Foam, which can be purchased from auto dealers or parts stores, respectively.
Additionally, it is worth noting that transmission fluid itself already contains a fluid package that includes cleaners. Therefore, a simple fluid exchange may be sufficient to clean the transmission without the need for additional additives. This is especially important to consider when dealing with automatic transmissions, as certain substances can cause significant damage. For example, water-based solutions can cause electronic components to malfunction permanently, and paper-based materials in friction plates and bands can be compromised.
While ATF may have been a go-to solution for older diesel engines, it is always recommended to consult a professional or refer to the manufacturer's guidelines before attempting any cleaning or maintenance procedures on modern vehicles. The use of ATF may not be necessary or advisable for newer models, and there are alternative products available that are specifically designed for cleaning fuel injectors and transmissions without risking potential damage or voiding warranties.

Biodiesel is thicker and will gel faster, but it can clean fuel tanks
Biodiesel is a type of diesel fuel that is derived from renewable sources, such as vegetable oils or animal fats. While biodiesel offers several advantages over traditional diesel, there are also some important considerations to keep in mind when using it. One key difference is that biodiesel is thicker in consistency compared to regular diesel. This higher viscosity can have an impact on fuel injection systems and engine performance. Additionally, biodiesel tends to gel faster, particularly in colder temperatures, which can lead to issues with fuel filters and fuel lines.
Despite these challenges, biodiesel possesses inherent cleaning properties that can be beneficial for fuel tanks. Over time, fuel tanks can accumulate deposits and contaminants that affect the performance and efficiency of the engine. Biodiesel has the ability to effectively dissolve and remove these built-up residues, improving the overall cleanliness of the fuel tank. This cleaning action can help optimize fuel delivery and restore the engine's power and responsiveness.
The cleaning capability of biodiesel extends beyond just the fuel tank. It can also help clean fuel lines, injectors, and pumps, ensuring that the entire fuel system operates more efficiently. This is because biodiesel acts as a strong detergent, containing various cleaning agents and additives. By periodically using biodiesel, you can maintain a cleaner fuel system and mitigate the negative effects of fuel system deposits.
However, it is important to approach the use of biodiesel with caution. While it can provide cleaning benefits, the higher viscosity and gelling tendency of biodiesel can pose challenges, especially in certain climates or with specific engine designs. Therefore, it is recommended to consult with a qualified mechanic or automotive specialist before introducing biodiesel into your fuel system. They can advise you on the compatibility of biodiesel with your vehicle's engine and guide you on the appropriate frequency and concentration for optimal cleaning results without compromising performance or fuel efficiency.
