Hi all, recently my 6MT 2006 TL 156km grinds during low gear up shifts, but is smooth when I wait a couple seconds before shifting, or when I'm going down a hill. There's also a bit of resistance when trying to go out of gear right away after the clutch has been depressed. I recently changed my transmission fluid to GM synchromesh and the clutch was replaced within 20k km. Do you think this could be a clutch hydraulics issue, or something different?

Thanks in advance.

Did you use ACDelco Synchromesh OR ACDelco Synchromesh Friction Modified?

There is a HUGE difference between the two when it comes to shift quality and transmission smoothness.
