The GTS is at 35k miles, so its due for a transmission service. What is the best fluid to put in? I've heard a lot of people say to only use the Mitsu Diaqueen fluid. Is that true? I noticed Redline has some CVT fluid, but I don't want to risk getting that and screwing the trans up.

 

unless your in canada or run your car in harsh conditions, your tranny fluid change shouldnt be for another 35k miles or so.

 

Stick with OEM fluid.

 

Thanks

 

Some people have had very adverse effects using non-OEM trans fluid. Get the Diaqueen.
