I have heard that AT 205 has caused paint on the inside of an oil pan to come off and clog the filter on the oil intake tube which causes the oil pressure to drop. Is that possible? In another forum a guy put it in his car to fix his valve seal leak (which it did work great for that) and after driving for a while the oil tube was clogged. He did let it sit overnight. Should he have put it in the engine just before driving the car instead? Just wondering if you have heard this issue before.
There is not paint on the inside of an oil pan. If a flushing fluid causes a clog its typically due to the solution lifting "sledge" from the bottom of the pan. This is possible in situations where the vehicle is already poorly maintained. Its debated in the car community if these solutions work at all and Scotty has a video explaining his thoughts on these products if you would like to review it.

There are painted oil pans, I have seen an used them including the oem lower pan for the 7AFE toyota engine. But I understand your answer regardless. Thanks
The outside of an oil pan is often painted. There would be no reason to paint the inside of an oil pan because there is nothing that prevents rust better than continuous storage of oil in one place. The oil itself acts as a rust inhibitor and paint is nothing but a rust inhibitor. Its possible that some oil pans are lined with a plastic PTFE but I have not seen it, at least not yet and I cant imagine what purpose it would serve other than to keep the oil from sticking to the pan (which only happens when a car is poorly maintained). Do you have pictures of an oil pan painted on the inside?
"I have heard that AT 205 has caused..." I'd definitely take that with a big grain of salt (ie, would just believe it) and wouldn't hesitate to put it in the trans (other than me being anal and just probably fixing it).
