5th gear "crunching" with shift

Auston

How many miles is everyone having these issues? As reported, mine was at 10k

I first noticed it at probably 500 miles and by about 3000 miles it was to the point where I can't skip 5th if I don't want to grind 6th and I have to shift slowly. My car is at 8500 miles now.

Very good question.. I started noticing problems at 8-10k.. didn't take it in until about 19k when I couldn't NOT shift 5th without grinding..

Then I was obviously aware.. had issues at 12k.. replaced.. then 15k.. kept taking it back.. took a couple visits before they would warranty on each occasion.. but ultimately it was evident that it wasn't me doing something wrong.

Now I'm technically out of warranty at 98k.. but I will say I have no issues.. and it's been probably 35k..

It's weird that most don't have issues.. but some do.. almost like it's an on-off switch to whether you'll have problems or not.

I'm hoping I now have a 'good' transmission.. and won't have to worry about it.

i first noticed it around 12k, but I'm only having the problem when I downshift to 5th, anyone else experiencing this? no problems upshifting, just when I downshift from 6th.

I have the exact same problem. I have to go from 6th to 5th VERY slow to not grind.
