Hint: Use a descriptive title for your new message
If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your G70, please post in the G70 section - and so on... This message can be closed by clicking the X in the top right corner.

After differential fluid change

I have a 2019 G70 2.0 rear wheel drive. Was hearing a slight whine from the differential so I changed the fluid with red line fluid(the 75w) with the 4 ounces of redline sliplock. Still makes the same noise. Is it a automatic differential change? Not sure if it matters or not but the only time it makes any noise is when I'm at 35 mph or above and only when I just barely touch the gas pedal or when I let up on the gas pedal.
