2000 Olds Silhouette Ticking.......flywheel/flexplate??????
 

I just had my transmission, torque converter and speed sensor replaced in a 2000 Olds Silhouette. But now I have a ticking sound in engine compartment, I called to guy that did the work right away and he said have the oil changed. I had that done but still ticking sound! Another mechanic told me it may be flywheel/flexplate is cracked or the torque converter installed is no good...... if anyone has any insight let me know please!!!!
