Product Details

Red Line Oil 30504 D4 Automatic Transmission Fluid - 1 Quart

Red Line Synthetic Automatic Transmission Fluids are designed to provide excellent low-temperature shiftability and improved thermal stability over petroleum ATFs. These fluids provide a much lower viscosity at cold temperatures for quicker shifting and their balanced frictional characteristics provide smooth and consistent shifts over extended drain intervals. The superior stability compared to petroleum ATFs also allow high-temperature operation without varnishing valves and clutches, which leads to transmission failure.

  • Provides a lower viscosity
  • Allows high-temperature operation without varnishing valves and clutches
  • Provides excellent low temperature shiftability

It was very good

Fast shipping


My satisfaction level literally could.not be higher! I ordered some tires online on a Saturday afternoon, and received a Shipping Notice, complete with a FedEx Tracking No., a short time later. And hat's off to their preferred shipper, FedEx, too!. Even though I placed my order only a couple of weeks before Christmas, I had my tires show up a day EARLIER than FedEx's original Delivery estimate! Product was exactly as ordered, and arrived in factory-new condition. So, no complaints ther, either... As I said, I would highly recommend to anyone!

Good shopping experience and customer service, but I need to return one item. I started the "return process" on Ebay a few days ago but have not heard back from yet about how to return the item. Can someone please respond to my email with the answer to my question? Thank you. WM Lovelock
