For the past 2000 miles i noticed that whenever i start my car and proced to do foward my bonnie makes a grinding noise going into 2nd gear only once after i start my car after that it does not do it at all until i turn off my car then turn it back on and procede to go foward again, my tranny fluid is full and clean, it drives and shifts smoothly but their is a very slight unsmooth transistion from 1st to 2nd, not bad but from a drivers satndpoint noticed slightly any body have any clue to what this minor problem might be.

my 95 LeSabre (4T60E tranny) does the same exact thing... makes that little grindy noise then shifts into 2nd... i got no idea what it is either

::whew::

My car does that too! I thought it was the tranny slipping, but that'* good news to hear. Man, I love this place. Everybody knows something.
