Synchros going bad?
 

Sometimes when changing from 4th to 5th the shifter gets stuck and doesn't want to move, and when I force it it makes a loud grinding noise.

Are synchros considered wear items? I'll take it to the dealership tomorrow.

Well it's not covered by warranty if that's what your asking

Doesn't it fall under powertrain warranty though? I have powertrain warranty until 100k miles.

If you can prove that it was defective then maybe, but they will just say you abused the clutch or grinded the gears and then won't cover it

I'd leave that part out when I explain the problem to the dealer.

Does it still do it when you double-clutch? Are you trying to power shift? Or speed-shift?

Yeah and no, just normal driving. It doesn't happen all the time though, just every now and then, but today it happened when I went from 1th to 2nd, and sometimes it doesn't want to go on 1th either. I'm taking it to the dealership tomorrow because my frs has been making a rattle noise when I'm on first and under 1.5k rpms, it started after I got my TOB replaced.

^^ Sounds like something is misaligned. The clue is that it started after the tob was replaced. Hopefully that hasn't caused undue wear on other parts.

I'll ask an obvious question ....... then refer you to @Ultramaroon

Do you have a short shifter installed .. ??

No. Everything is stock on this car.

Firs change fluid, drive for a while. Also at what rpms you are shifting?

Good point!

However, first off ...... check the fluid level to make sure the folks that installed the new TOB put oil back in the transmission........:popcorn:

***How many miles after your TOB replacement now?

Rattling noise at low RPM may or may not be normal. By itself I would say nothing wrong. Factory gear lube is super thick in an effort to keep it quiet.

If the transmission was under-filled That would make shifting more notchy and picky, especially after it gets hot.

I'm not an expert with dealer service interaction and I'm suspicious of other peoples' work. That said, If you have any intention of following up with a warranty claim, do... not... touch... anything.
