In 2004 and 112k on engine I flushed trans oil with Redline C+ATF. No problems with tranmission. In 2008 and 138k on engine I flushed trans oil with Mobil1 Synthetic ATF - Multi-Vehicle, so far no problems and 8000mi on oil. The Mobil1 label on the back reads:

"Mobil1 Synthetic ATF is formulated for use in most North American, European and Asian vehicles."

"Also suitable for use in automatic transmissions for the following applications..... Mitsubishi Diamond SP-II, SP-III.."

I'll let you know if my trans fails.
