I've noticed this in my car as well. Not very often, but their has definitely been a few times where I've been frustrated thinking wtf
. I've only noticed it at high rpm shifts (6,000 or higher) from 1 to 2 along with that horrible grinding sound. I've had it also pop outta gear into nuetral one time. 13,xxx miles on the car. I'm hoping it's nothing to serious, but if it continues in spring once i pull my car back out i may have to have it checked out.
