Just got my 4l60e trans freshened up.

The vig 3 dish 3600 converter worked great so I didn't send it in for anything. The trans shifted fine before just would slip at high boost athe track.

This was just a normal refresh, nothing was broken and fluid was perfect before.

It's very strange as this noise for no reason at all will totally disappear. I can drive it all day with no noise, stop some where start it up and noise is there. Only in drive and reverse,not neutral or park.

I know converter is the usual suspect but keep in mind it never made this nois before. The converter is exactly the same.


Thanks
Alex
