So you lost me on the extra cooler. I dont have the extra cooler so the return line goes into the radiator. So if it is stock. Is it the top one or bottom one?
I think the previous owner just added water in the transmission reservoir. Oh man.. I hope its not that serious. What can I check before I have to get a new transmission? :/
So I got this 73 chevy c20 cheyenne 350 and I checked the tranny fluid and its a milky pink.. the radiator coolant was a rusty mess, so I'm wondering if rust might have gotten in there too.
My real question is how do I drain. Flush. And properly add fluid and exactly what type of tranny fluid...
