Often the "POP" is when the flywheel and torque convert kinda straighten themselves out whien you are tightening th transmission bolts (let's hope that's your case). Other times that 'POP" is when the transmission case breaks. Check the area around each transmission bolt to see if the case is cracked.
If no crack (yeah!), Now see if you can turn the torque converter by hand. It should be easy to spin. If so, the flywheel and torque converter are aligned. If not, remove the transmission bolts and slide the transmission back (away from the engine) enough to align them by turning the engine or flywheel. Let me know how it goes.
