Hello,
I asked this over on the Mitsubishi group, but didn't get a very big response. I have an 03 Mitsubishi Outlander. I recently got the transmission flushed at 30k. When I went in, the recommended fluid that showed on their computer was Diamond SP III, which is what the manual calls for. I asked the guy if that was in fact what he would use, and he told me yes. Then as I'm getting the car, I see his guy putting an additive in. Turns out he just used a more standard fluid, and then put in the additive to get it to the right spec. I don't trust this... Especially since the guy came running out at the last minute and popped the hood to add more of the additive. I have no idea if they even got the ratio right. I use to do this stuff myself, but I am currently not in a position to be working on cars very much. I could possibly do something myself if it doesn't involve having the car jacked up. I'm interested to hear what my best option is for getting the stuff they put in totally flushed out, and the SP III put in. I'm leery about going to the dealer, because I know they'll want some outrageous amount of money, and they also log everything you do... I don't want to deal with an argument about this voiding the warrantee or something someday. I'm not going to bother going back to the original place, because they don't have the right fluid anyway. It's amazing that simply changing a fluid can be such a pain now days.
Thanks for any help,
