As a car owner, staying informed about your vehicle’s health is crucial. Modern cars are complex machines, and diagnostic tools like OBD2 scanners have become indispensable for both professional mechanics and DIY enthusiasts. Among these tools, BlueDriver OBD2 scanner has gained popularity for its user-friendliness and comprehensive features. However, when it comes to specific functionalities like reading transmission codes, particularly transmission fluid temperature, it’s essential to understand its capabilities and limitations.
This article delves into whether the BlueDriver OBD2 scanner can effectively read transmission codes, focusing on the crucial aspect of transmission fluid temperature (ATF temp) readings. We’ll explore user experiences, discuss alternatives, and provide a clear picture of what you can expect when using BlueDriver for transmission diagnostics.
Can BlueDriver OBD2 Read Transmission Temperature? User Experiences
A common question among BlueDriver users revolves around its ability to monitor transmission temperature. Online forums and communities, like the ih8mud forum, are valuable resources for real-world user experiences. In a discussion on this forum, several users inquired specifically about BlueDriver’s capability to display live transmission fluid temperature data.

One user, kcjaz, initially sought confirmation on whether BlueDriver could provide ATF temperature readings, expressing surprise at not finding it within the app’s live data options. Another user, FrazzledHunter, shared their direct correspondence with BlueDriver support from January 2020. The response from BlueDriver explicitly stated: “Unfortunately transmission temperature is not part of the OBDII standard live data set and is not currently supported by BlueDriver.”
This direct confirmation from BlueDriver support clarifies a key limitation. While BlueDriver is a powerful OBD2 scanner capable of reading a wide range of data, it does not inherently support transmission temperature readings as part of its standard OBD2 functionalities. BlueDriver’s response also mentioned ongoing Research and Development into displaying ATF temperature for Chrysler & Toyota vehicles, indicating a potential future update, but with no firm ETA.
Further discussion in the forum thread highlights that BlueDriver’s limitation seems to stem from its adherence to the standard OBD2 data set. Competitor devices and apps are mentioned as being able to display transmission temperatures, suggesting that the data might be available within the vehicle’s system, but not accessible through BlueDriver’s current standard parameter set.
Why is Reading Transmission Temperature Important?
Monitoring transmission fluid temperature is crucial for several reasons, particularly for vehicle longevity and performance:
- Preventing Overheating: Excessive transmission fluid temperature is a primary cause of transmission damage. Overheating degrades the fluid, reduces its lubricating properties, and can lead to premature wear and failure of transmission components.
- Towing and Heavy Loads: Vehicles under heavy load, such as when towing, experience increased stress on the transmission, leading to higher fluid temperatures. Monitoring ATF temp in these conditions allows drivers to adjust driving habits to prevent overheating.
- Fluid Level Checks: Some vehicle manufacturers specify a specific transmission fluid temperature range for accurate fluid level checks. Knowing the ATF temp is essential for ensuring correct fluid levels, which is vital for transmission health.
- Identifying Potential Issues: Abnormally high transmission temperatures can be an early indicator of underlying issues within the transmission system, such as low fluid levels, failing torque converter, or internal leaks.
Alternatives to BlueDriver for Reading Transmission Codes and ATF Temperature
While BlueDriver may not natively support transmission temperature readings for all vehicles, there are alternative OBD2 solutions that do. The forum thread and broader automotive community suggest several options:
-
OBD Fusion with Enhanced PIDs: OBD Fusion, paired with a generic ELM327 OBD2 adapter, is frequently recommended as a reliable alternative. Crucially, OBD Fusion supports “Enhanced PIDs” (Parameter IDs), which are manufacturer-specific data points beyond the standard OBD2 set. By purchasing and installing Enhanced PID packs for specific vehicle brands like Toyota, users can access transmission temperature data, along with other advanced parameters like oil temperature.

Carista: Carista is another OBD2 app and adapter combination that is mentioned as offering transmission temperature monitoring, along with advanced diagnostics and customization options for various car brands.
-
Torque Pro (Android App): Torque Pro is a popular Android OBD2 app known for its customization and extensive plugin support. With the right plugins and PIDs, Torque Pro can also be configured to display transmission temperature and other advanced data.
-
Generic ELM327 Adapters: Many users report success using inexpensive generic ELM327 OBD2 adapters (Bluetooth or WiFi) in conjunction with apps like OBD Fusion or Torque Pro. These adapters act as the interface between the vehicle’s OBD2 port and the smartphone app.
It’s important to note that accessing transmission temperature and other non-standard OBD2 data often requires using apps and adapters that support Enhanced PIDs or manufacturer-specific protocols. BlueDriver, in its current form, primarily focuses on standard OBD2 diagnostics and may not offer this level of in-depth data access for all vehicle makes and models.
Conclusion: BlueDriver and Transmission Temperature Monitoring
In conclusion, while the BlueDriver OBD2 scanner is a robust tool for general vehicle diagnostics and reading standard OBD2 codes, it currently does not natively support reading transmission temperature for all vehicles as part of its standard feature set. User experiences and direct confirmation from BlueDriver support corroborate this limitation.
For car owners specifically needing to monitor transmission temperature, especially for towing, fluid checks, or performance monitoring, alternatives like OBD Fusion with Enhanced PIDs, Carista, or Torque Pro paired with ELM327 adapters are recommended. These solutions offer access to manufacturer-specific data, including transmission temperature, providing a more comprehensive view of vehicle health.
While BlueDriver may introduce transmission temperature monitoring in future updates for certain brands like Chrysler and Toyota, as of now, users requiring this specific functionality should consider exploring alternative OBD2 tools to meet their needs. Understanding the capabilities and limitations of your diagnostic tools ensures you have the right information for maintaining your vehicle effectively.
