Yes to the fluid. There's really no way to flush the trans.

 

alright,
i have the royal purple in there now,
(is it just me or does tranny oil stink?)

the RP synchromax was actually purple...
looked like thick kool-aid.
but i noticed as soon as i took it for a spin 3quarts later,
that the 3rd gear downshift was much smoother,
but i said great things about M1S when that was fresh in the tranny,
lets see if it stays working nice.

 

Yes, it does. Most kinds, anyway.

 

i smelled it the first time
but this time it was worse,
and then the brake cleaner,
i was pretty much high off fumes,
and i smelled like something i cant describe...
its like sulphur.

 

That sounds like an extended Haiku

 

hahaha,
ill make millions with my writings.

 

Synchromax doesnt have a rating but works just fine, I had the same doubt you do. Erased when changed the oil. A little note of help, buy a wrench that can fit the drain plug, since its so damn close to the front suspension, a ratchet and the 20-ish mm will not fit nicely.

Also dont even think about doing it with an impact hammer, as it can strip the drain plug a bit, and if you ever take your mitsu to warranty for tranny, Youll have a bit of explaining to do....that was my personal experience

 

looking to doing this myself. is it pretty straightforward? like a basic oil change?
