Can not stop oil from leaking.

not an option for me but i guess a700r4 is ok.if you puth the trans in and didnt use the factory dowel pins, how did you line up the input shaft on the trans? if it isnt within .001 or .002 it puts the input shaft in a bind and WILL break the flex plate, tear up the front pump bushing, and eventually wipe out the rear main, and the torque converter snout that runs the front pump in the trans. none of this is good. post more on this so we can help!
