transmission/torque converter

Hi, i'm back. I have a 91 ford tempo that we just replaced the tranny on about a week ago. and the car is doing the same thing before we put the tranny in, so with further investigating we beleive it the torque converter that we did not replace. So my question is how do you remove the torque from the flexplate that goes to the engine. there no room to get to the bolts is there a special tool or trick. if anyone knows please help, Thank you
