Yo,
been trolling through the posts, cant make sense of which fluid to replace mine with. 102k on the tranny, 1st and 2nd is a hard shift. Leveled the car, tranny is pretty dry. Read something about synthetic motor oil? Can anyone reply with a link to some good options.

 

My other car is an older Miata and it's 5speed was trashed by the previous owner I tried 5 different fluids all synthetic and the best was redline MTL. It's thin but worked the best. My CF is an auto just thought I'd chime in.

 

I tried a lot of trans fluids and got the best result with factory MB gear oil from Needswings.

Thanks y'all!!! I'm hoping it's just a dry issue since i only started noticing hard shifts a few months ago. I never noticed the 1-2 hard shifts before like everyone talks about with our transmission. Knowing my luck though that's probably it :'D

 

Royal Purple Gear Oil 75/90 WT. expensive but works great in manual transmissions and rear diffs.

Start with the Owners Manual recommendations, then cross reference with the specifications, then get whatever you want after seeing that information. The 'minimum' is a 'baseline'. Your choice after that will be based of who and what convinces you on what to install in it. Good luck!
