This TriboDyn gear oil will be excellent for your 2015 Ford. Hypoid gears in trucks need strong load protection. This gear oils starts with a Full Synthetic oil base, then we add our patented TriboDyn additives. The result is a gear oil with extremely high cling rates, impressive shock and load protection, and extreme durability. Please let us know your results. Thanks **Q: Would this fluid work well in a g56 6speed in a dodge 3500 4x4 transmission?** A: A Dodge 3500 calls for 75W-140 in the front gearbox and 75W-140 with a friction modifier in the rear. Both must meet GL5 specs. TriboDyn 75W-140 meets GL5 specs. You would need regular TriboDyn 75W-140 for the front and TriboDyn 75W-140 Limited Slip for the rear. You will notice smoother shifting, a quieter ride, and lower gearbox temperatures. **Q: How does it perform in cold weather? What’s the coldest pour temperature?** A: The cold weather characteristics are similar to all 75W-90 full synthetics. The pour point is -9°C to -36ºC (15.8°F to -32.8°F ) (Typical or Target). The one difference you may see with TriboDyn is a much higher cling rate. Check out our videos which show how much better TriboDyn clings without increasing drag. This is critical in cold start up protection. **Q: Is this recommended for my 2014 Audi S4 with rear sport differential?** A: Your vehicle calls for 75W-90 gear oil for both the main transmission (3 liters) and the rear differential (2 liters). It has an electronic differential control so you do not need limited slip gear oil. Heat is usually an issue in transmissions and differentials so our regular TriboDyn 75W-90 Full Synthetic Gear Oil is would be excellent for your car. BTW, great car! ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Bright color *by A***R on Reviewed in the United States on September 5, 2021* You will know if you ever have a leak because of the blue color. Time will tell on how good it is. Can't rate performance until it has been used for many miles. Should be fine, developed in NASCAR country. If not, they won't survive there. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars The best V-twin transmission oil I’ve used in my Baker 6 speed *by A***. on Reviewed in the United States on January 28, 2022* Interesting intense blue color. Made shifting easier, less clunk going into first, also finding neutral is way easier. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Amazing product!!! *by V***D on Reviewed in the United States on July 7, 2020* The product was delivered fast.
