Customer Review
works as advertised
Put this in my '00 Audi S4 and the car shifts alot smoother. Probably will buy the 12 pack to get older stuff out but there IS noticable improvement in the transmission. It does meet Audi esso LT71141 requirements so you should be ok putting it in the Audi ZF transmissions.

Red Line D4 Automatic Transmission Fluid
I have been using the Red Line D4 for all my automatic vehicles, past and present. It has provided smooth shifting and protection for the vehicles I have used. Even my current 218k+ '97 Honda Accord. Huge difference from what was in the car when I bought it used til I used the Red Line.

I Use D4 in my 2 Previas and my Mustang
I've been using D4 in my 1970 Ford Mustang Mach 1 since upgrading to an AOD from the original FMX. I had a stock of Valvoline Dexron/Mercon ATF originally for my 1991 Toyota Previa LE and changed the fluid frequently as possible. I then bought my uncle's (who is now deceased) 1995 Previa LE S/C and knowing him he never changed the fluid in the 16 and half years (from when it was new). In the 95 Previa I initially used the stock of Valvoline ATF I have and within two weeks it started to shudder because it circulated the fluid around and turned black in the pan. I changed the fluid again this time with 1 quart of Redline D4 and my remaining 2 quarts of Valvoline. The transmission feel has improved but I have to check periodically if the fluid has turned black from my uncle's poor maintainance.

Product Description
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. Top to learn more
