sludge in coolant reservoir

We Installed an external transmission cooler to eliminate the chance of mixing trans. oil through trans. cooler in radiator. Fully flushed coolant system but are still getting a grey gelatinous build up in the reservoir. Recently oil pressure has decreased at idle to now 10-15 psi at idle when hot. No major loss of oil or trans fluid or change in fuel economy. Has anyone else had the same problem and if so what was the fix? thanks.
