I was going to removed the automatic transmission oil pan on a '01 PT Cruiser because of a leak. I guess I’ve lived a charmed life and never had to deal with getting something off that had formed-in-place gasket versus old style. How do I get it loose – try a knife blade ??
Yes, a large knife tapped in with a hammer will break the seal. Just use a little common sense about how much force you use…I would leave 3 bolts loose but in place so pan just doesn’t fall off when the seal is broken…This can be a VERY messy job…
And when putting the pan back on, here’s what to use. http://www.permatex.com/products/Automotive/automotive_gasketing/gasket_makers/auto_Permatex_the_Right_Stuff_Gasket_Maker.htm

A good gasket scraper makes the job easier. You can use it to pry the pan loose and then use it to clean up the mating surfaces.
