Transmission Pan leak

I failed at replacing the transmission gasket the first time and maybe a second time.

Hey Scotty, i replaced the fluid and filter on my nissan last year, about 1000 miles of driving ago. I noticed some leaks coming from around the bolts which got bigger over time, starting to leak from the sides of the pan, even after i tighted them when i found some to be loose. I didnt do a good job the first time and the gasket got in the way of some of the bolt holes. The second time i followed your method of letting the gasket dry on the pan for about 30 minutes before putting it back on, using a few dots of RTV to hold it in place and the bolts went in fine by hand before being made snug. Its been 100 miles since and today i noticed a few drips on the pan in the same places but around different bolt holes. I checked the bolts, the pan holes and the holes on the transmission and they were clean and undamaged. What did i do wrong?

I used the gasket shown on the left which is a thick, rubber type gasket that is wide and sticks out the side of the pan after torquing. Should i use the gasket shown on the left? I tried doing it in a criss-cross way but unsure if that has effected it. Could you number the torque pattern if you think that would help?

Cheers.

both pan and bottom of tranny must be whisper clean, I use scrubs to knock all that stuff off and not gouge holes that may leak
