How to Choose the Right ATF
Because ATF specifications differ widely across manufacturers, selection should always start with your vehicle manual. Here’s a quick checklist:
- Match the exact OEM requirement (DEXRON, MERCON, WS, T-IV, DW-1, etc.)
- Use low-viscosity or conventional viscosity, based on the manufacturer’s design
- Avoid mixing unrelated ATF types, as friction characteristics vary significantly
- For older or high-mileage transmissions, consider a conditioner like BG ATC Plus
- Change fluid at proper intervals, especially under towing, in hot climates, or during heavy commuting
Understanding BG Automatic Transmission Fluid
BG automatic transmission fluid and additives are formulated to improve performance in both older and modern gearboxes. Their products include full synthetic ATFs and conditioners such as BG ATC Plus, commonly used by professional mechanics to eliminate rough shifts, reduce torque converter shudder, dissolve deposits, and rejuvenate worn seals.

What BG ATF Products Are Designed To Do
- Improve thermal and oxidation stability to reduce sludge and varnish formation
- Maintain proper friction characteristics for smooth shifting
- Reduce shuddering and slipping, especially in high-mileage transmissions
- Condition seals to prevent leaks and restore pliability
- Protect internal components from wear under high temperatures
- Enhance fluid longevity in heavy-duty or severe-service environments
BG products are popular in workshops because they can restore lost performance without the risks associated with harsh flushes or generic additives. For drivers, this often translates into smoother operation, fewer leaks, and prolonged transmission life.
When You Should Consider Using BG ATF
You might benefit from BG ATF or BG conditioners if:
- Your transmission is experiencing delayed shifts, rough engagement, or shuddering.
- You notice small leaks due to shrinking seals.
- You want to reduce friction and temperature buildup in a high-mileage transmission.
- You want a full synthetic alternative that meets or exceeds many OEM requirements.
- You’re maintaining a vehicle used for towing, hauling, or stop-and-go city driving.
