Jus got trans and diff oil changed 300 miles ago everything was fine til last night. Today it's fine to I don't get it

Hmmmm, try a lengthy drive maybe thirty minutes or so.

With launches and high rpm driving

i drove for like 45 min today. then i took it to the dealership where i know a buddy thats been working on z's for 6 years. hes a close family friend. he took it out and drove it hard for a good 10 min he said the clutch is fine all the gears are smooth synchro is good and he even did the 3rd gear test where he puts it in 3rd then lets go of the clutch...the car stalled so the clutch is good. csc is fine. only thing is he said in the future change or bleed the clutch...but even though the fluid isnt golden or new looking right now he says its nothing to worry about at all . he drove it and he said "no offense james but if this is your first mt car these things happen lol" maybe hes right...maybe im jus dumb

Yeaaaaa that was my initial thought ;) I kid op

but yo that that ***** crazy..theres no way i mis shifted 12 damn times in one night lol it was bad...today i didnt mis shift at all...
