How do I flush transmission cooler lines and trans cooler???
I am about to start the swap out of my 4l60e after it died a couple of months ago. Apparently the pump went out. The tranny pan had a lot of gray sludge (metal particles) in it.
I am going to be replacing the tranny and converter.
I need to know what is the best way to make sure I get all the junk out of the tranny cooler lines and tranny cooler. I have the stock tranny cooler lines and a B&M Supercooler.
THANKS

I used an old fuel pump off of a 4.8L truck that worked great. I flushed a jug of mineral spirits through until it came out clear, and then flushed two quarts of tranny fluid through until the mineral spirits were flushed out. This was all done at the recommendation of Vince at FLT. FWIW, the junk that initially came out was black and about as nasty as anything I've ever seen. Unfortunately, a lot of folks skip this vital step when adding a new tranny.
