tranny question

My car smokes quite a bit if I get on the gas hard to pass someone or when I launch.

I know the oil pan gasket has a small crack in it which has probably got worst. <This is what I think it is....Someone else told me its probably a cracked bellhousing gasket...which didn't make any sense to me
 
nope. the engine's rear main seal and the tranny input shaft seal contain their respective fluids. so there is no need for a seal (most bells dont mate air tight to eachother). also, if there was a seal, the dust boot on the shift fork would spew fluid. :)
