Sc300 Transmission Fluid Recommendations

[JDOwen2]

Has anyone had success with anything other than Dexron II in their automatic transmissions? I just turned 90,000 miles and the trans is shifting hard at times and shuttering at times.

For the SC300, stick with the Dexron family. That's what is recommended, that's what you should use. If you're talking about different types of Dexron ATF... I've used the Mobil 1 synthetic ATF and Valvoline MaxLife dino oil ATF. Both are Dexron II/III compatible oils. It seems to shift a little bit smoother with the Valvoline. I've been using their MaxLife motor oil and the valve sounds seem to have diminished a bit also. Change your tranny oil often...
