Ok so im still waiting on a response to one big question

Is the ATF with the oil change a permant solution for stopping leaky valve guide seals? or would i have to do this every year, or every 2 years?

Ok, so id like to give this a try, and i can use any full synthetic ATF, and for the 2 hundred miles i drive with the atf and new oil, can i just keep the old oil filter on there?
