My '83 245 auto trans. leaks pretty constant where I have to add a quart about every oil change (3K miles). There's a decent amount of oil also leaking from the front area of the trans. that I suspect is the rear seal going out as cleaning the flame trap doesn't seem to help. So before I pull this trans. out which I plan on replacing that rear seal which other trans. seal(s) do y'all recommend I replace to get these leaks to stop? which ones are most prone to fail? I only want to do this once. Thanks, Charles
