My question is: What kind of fluid is the best value for the L400 transmission? I know that the manual suggests Diaqueen SP-2 ATF fluid, and I want to treat my transmission like a baby so that it lasts a long time. What brand/type do you use?
Chrysler ATF+ is a recommended replacement for Diaqueen SP-2+
Redline ATF D4 is the equivalent to SP-3
I found this thread, which the listed ATF meets the requirements:

Flush every 30-35000 km and not break the bank

And this thread, but Redline is $$$ from what I remember

In the interior or place that hit below 20 throughout the winter, D6 is the fluid to use.VanVonVan wrote:So you flush your transmission every spring and fall I thought a tranny flush was once every 2 years?jfarsang wrote:For winter use Redline D6 ATF and summer ATF D4.
You'll be pleasantly surprised at how much smoother your auto will shift after using this fluid. It's amazing stuff.
Redline D6 is what the SARS/ambulance rigs use in northern BC and if you ask around, the Toyo/Cummins crowd in AB/SK as well.
Just like going from a low quality 15w40 to a synthetic 5w40 in the winter does to your engine, going from Dex to Redline is similar for your transmission and transfer case.
Any suggestions or additional info would be greatly appreciated!
