Well I ordered a bulk roll of Dayco transmission coolant line and am waiting for the stainless worm clamps to get here. I am getting ready to replace the tranny coolant lines from hell that I was lucky enough to find were leaking during my last oil change. My question is 'how many quarts are needed when draining the tranny pan?' I know I've lost some fluid and I've bought 3 quarts of the new Nissan S fluid to do a poor mans tranny fluid change while I replace the hoses, but I know I'll need a few more. Any ideas?
