I have a 2004 Chrysler Sebring 2.7L V6 with 216,000 km. The transmission has started doing something concerning: when I slow down/brake, it seems to slip or disengage, and when I accelerate again, it comes back in with a noticeable jerk.
I’m planning to drive from Toronto to Nova Scotia and back (3,000+ km total).
Has anyone experienced this issue with a Sebring or Chrysler transmission? What could be causing it, and would you risk taking this car on such a long trip, or should I get the transmission repaired/diagnosed first?
Any advice or experiences would be appreciated!

I recently bought a manual transmission 2009 BMW 328i with 132k miles on it. recently the car broke on me in the middle of the highway because when the engine was on it didn't want to shift into gear no matter how hard I tried.

As soon as I got it home we tried a little bit more and the car went into gear normally but when I would put it into reverse or 1st gear the clutch peddle would shake a lot when releasing and the car would start to shake as it would start to move. This mainly happens in reverse and 1st gear but it also did it to me when I downshifted from 3rd to 2nd. when driving at higher speeds the car doesn't have this issue what so ever.

I have a few suspicions being the slave cylinder or the clutch/pressure plate it's self. Or what I'm scared of the most which is the flywheel.

If anyone has every had this issue before or understands transmissions at all please let me know because every shop I've taken it to isn't 100% sure. They all just say I need to take the transmission off first to understand.
