Hi!

I have a problem with my tranny.
Some days ago, I did a kickdown at ~80mph and rpm increased very fast, like a clutch was not holding, then there was a loud *bang*, and I had no gears any more. No reverse, no drive gears, even though rpms decrease about 50-100 when a Drive gear is engaged.
Just one week ago I had my tranny serviced, new atf & filter.
Now, the ATF is dark brown but does not really smell burned, and you can hear a whining noise while the engine is running.

Anyone has an idea what went wrong?

In a couple of days i'll get that tranny out of my car and start the rebuild.
Hope it doesn't get too expensive :/
