This is somewhat related to the problem. do you guys ever have the Reverse gear grind when your driving, stop, and switch to reverse? Happens to me when I'm about to park reverse numerous times.

when you put it in reverse you need to go into 1st gear first bc or the safety the trans has on it so if your not going 1st then reverse thats why it grinds

Reverse doesn't have synchros in the gearbox, all cars will grind going into reverse if the countershaft in the trans is still spinning. Every stick car I've ever driven will do the same thing, doesn't matter whose it is.

when i first got my car it was grinding in reverse but i was to that if you go into 1st then reverse it wont grind thats what i do and now it dont grind lol but that is true most car will grind into reverse but not all do

My tranny's fine. *crosses fingers*

Now for those with the reverse-crunch, if your synchro's aren't aligned when you try to shift into reverse, you'll get resistence...and a crunch if you pull too hard and force it. Simple solution for this common problem across all manufal transmission cars.

Just reset the clutch - and try again.

2 questions. Does this only affect the 2009 corollas? And at what mileage did people start to notice the 3rd gear grind?

The TSB only applies to some 2009 models produced before the vin showed at the bottom, however, the OP has a 2010 and is experiencing a 3rd gear grind issue.

I noticed the problem on the first test drive at 11k miles. I chocked it up to being unfamiliar with the car. My car only does it on the 1st or 2nd 3rd gear shift on sub 40 degree days. If I shift super slow in to third gear, it doesnt grind. Shifting at a NORMAL speed, however, produces a nice crunch. If ya' cant find it, grind it, right?! lol.

I wonder if it could be a tranny fluid viscocity issue, since you said its worse when its cold. Meaning when the fluid warms up it goes away or is better. If it was strictly a syncro issue i would think it would happen all the time.
