Default 3rd gear grind

Just got my m6 swap in everything new besides the slave and t56. (new cltuch and master). It will grind 3rd gear when shifting it about 60% of the time. I was told that it has a bad syncro. I guess thats what i get for buying used **** online.

Very possible. It's also possible your clutch is dragging, so you should do the clutch test just to make sure it's not a disengagement issue. Being that it's only third gear and not any others, though, you're probably correct that it's an internal tranny problem. Just a thought.

the clutch test came out fine, theres no disengagement issue. im pretty sure its a syncro. i just want the guy to see who sold me this unit that something is wrong. it grind 3rd no matter how easy i shift it . it needs to be fixed before i ruin the gears in it correct ?

yea the whole point of me making this thread is to show the seller that the tranny is messed up from day one and to atleast split the cost of the rebuild with me before it costs even more money and then i will be forced to take legal action
