Any ideas/help to find/fix this “Disappearing” fluid from the manual clutch reservoir - 2017 F3-S

BCNewell · 2026-10-07T20:37:09-0400

Looking for some help from those of you who have/had a manual shift Spyder. My ‘17 F3-S Daytona has been losing its manual clutch DOT4 fluid somewhere. I can find no sign of a leak. Park it on a concrete floor and nary a drop is seen under it. No leak at the reservoir lid. It will go anywhere from 500 to 1,500 miles or so before it is empty or near-empty. This has been going on for almost 2 years/~9K miles. I would like to find it myself and repair it, if it's not terribly involved or expensive. I DO still have remaining B.E.S.T. warranty on it through May of ‘27,

but I'm not sure of the competency of our local dealer - especially on a rare 10-year-old SM6. Thx in advance for any help.

I believe your brake fluid leak is going internal, that's not good!
Where did you buy a B.E.S.T. warranty that lasted 10 years?

Easy - I bought the 2017 new and untitled w/ only 82 miles on it in 2022.
