Any suggestions on what may be causing a hard shift from 2nd to 3rd gear? It's hard enough to jerk the car. Base on my observations, it only occurs when the trans temps are cool/engine not up to operating temp. It does not occur every day...maybe once/twice a week and I drive every day. With the car at operating temp and trans temps above 80 deg F, it has rarely ever occurred. I'm stumped on this one. Thanks for any input.
I just bought a jetta for a cheap price that had this same problem. i hooked up the vag.com and it said valve 6 (solenoid N93) short. I have been looking on here and reading a little bit about all the solenoids on the O1M tranny and it seems to be a common problem.

I know its not a O1M tranny he is referring to but it will give you an idea.
Hope it works for you
You could have a common problem where the TCM stops commanding pressure drop during a shift.
See this post...
The TCM will sometimes stop commanding pressure drop on a specific shift. The thread that I linked to shows how to test for this.
Auto trans fluid change or flush will not make a trans fail. Stop spreading the wives tale/urban myth.
