Auto trans fluid change or flush will not make a trans fail. Stop spreading the wives tale/urban myth.

I just did this on my 05 Jetta TDI which has been shifting odd since I bought from my sister. She never had a problem so hopefully this takes care of the "missed" shifts, slamming into gear, coming out of OD at 76mph, etc. No codes either!! I will find out on the drive home!
