small leak trans pan gasket. said need thicker gasket. Tighten bolt order. .

Have found four or five bolts have rubber washers on them and others do not. Those with rubber washers do not leak, so I guess, duh, I need to put on new gasket and put rubber washers all all bolts and they do all tighten up good very snug. Leak isn't blowing to other things such as exhaust, it's only after parked. Leak leaves spot about 4" dimeter. When putting bolts on they should be tighten in a cross pattern right? I live in a highly populated mixed nationalities. Been ripped. Dealership or high cost shop is only option. One wanted 225.00 to change.
