I pretty certain it's 72 inch pounds; some aftermarket gaskets might recommend 100-120 inch pounds. I would recommend using a genuine Nissan trans pan gasket. Also, Nissan recommends replacing all of the pan bolts as they have a sealant applied to them. These bolts can be purchased from Nissan; sometimes they are sold individually and sometimes they are sold in a bag under one part number. Re-using the bolts without sealant on them can also cause leaks. Nissan transmissions typically don't have the screen (aka "filter") serviced. If there's enough debris to clog the filter, then it doesn't need a service, it needs an overhaul. Also, be careful of what transmission fluid you use. If it came with Nissan-Matic Type "D" ATF, do NOT use Dexron III, as it's thicker viscosity can make the valves stick in the valve body. Stick with either Type "D" or a transmission fluid recommended for Dexron/Dexron II applications, which most synthetics do. Some good aftermarket options are Valvoline Maxlife ATF and Castrol Transmax J Multi-import ATF.
