I bought my transmission that came out of a Cadillac that had 55,000 miles. It had been sitting awhile. When I installed it, I put new fluid and filter in it. I filled it with new Royal Purple transmission fluid. I ran it around 200 miles. The gasket was leaking so I replaced the filter, gasket, and fluid. I kept the fluid I drained out. Is there a way to strain this fluid, I drained out, to use it?
