tranny filings

The gooey stuff is generally clutch disc/band lining material. To have that much in a 1 yr. old 3000 mile trans. is not good at all. Do you have the throttle pressure linkage hooked up and working properly? Does it have a shift kit in it? If so what brand kit?

One more question. When you had the trans done a year ago did they flush the cooler and torque converter? If not that may be where some or most of the garbage came from.
