i had a 1988 190e 2.3 automatic transmision us version i had a problem with the transmision oil pan it has a leak and i am having a hard time fixing it. i had the filter, oil and gasket replace but i can't stop the leak that coming from the pan (gasket) side

my question is that is there a technique on how to screw the pan how much tourque is neede to each screw, is there a squence on how to tighten the screws. let say screw no.1 is the pasenger side front, screw no.2 passenger middle, screw no.3 passenger rear, screw no.4 driver side rear, screw no.5 driver middel, screw no 6 driver front.
