We are talking about a totaly different trans! Use regular ATF, change it every 25k miles or whatever they call for. I prefer Mobil 1 ATF I think it makes these old trans shift a bit better.

Interval on the 90 is 30K, and use any fluid that states that it is DexronIII/Mercon. The synth already recommended is OK as long is it states that it "is" or is compatible with DexronIII/Mercon.

You guys can change fluid all you want, but I'll be flushing mine with a flush machine. on my 300E, look at the crappy paper filter. What is that going to catch??? When you are talking microns...very little. Several shops that know what they are doing are now hooking a flush machine into one of the cooler lines and give a complete flush. They have a sight glass and can watch the fluid go from black to bright red. Most will use 16 quarts or more during the flush. And just because it looks red on your finger when you pull out the dipstick, doesn't mean anything. Pull out a sample and fill a test tube! That red on your finger, will look quite black in a test tube. My opinion....flush it! don't drain it.

Now I can't speak for those late models with no dipsticks, but most transmissions, even the late autos, have a plug somewhere for level check, even if there is no stick. GM and Ford did so, when they got the stupid idea to save a few bucks and delete your dipstick.

Only an opinion, but doing nothing, not changing or flushing, is about as stupid as not changing your oil.

Yes what you say is true, unless you have a 722.6 or newer trans.

Good for them. Meanwhile, I'd rather weight the dice and throw a 6 every time by changing the fluid regularly.
