don't know if it's just me, but i only use a 1/4" ratchet & just gently tighten pan bolts. i've never had luck at 150"lbs. seems the gasket smashes out or the pan bends up! just have to keep eye on bolts for staying tight. haven't found a sealer yet that would work and still allow pan removal. how come nobody makes a pan with a thick flange like the front drive trans? then you could use rtv with no gasket! just my 2 cents.
