Just performed a fresh rebuild following the ATSG manual, everything kept as stock as possible, just trying to help a family out with a daily driver. It's an '04 suburban, with 100,000 miles. Rebuilt because of slipping 4th that's all I know. The problem is when I reinstalled I'm getting a slight clicking noise at about 150+ PSI line pressure. I'm using a snap-on scanner to engage the boost control. Sounds more like the front of the tranny. it also makes this clicking in reverse, but I haven't driven it in fear of ruining the rebuild. The only thing I missed was TC install on the pump, but fixed it before running, also took it back out to check for cracked oil pump after I heard clicking, but no problems there. Also, line pressure across the range was a little low, planning on adjusting the boost control, pressures using the scanner were: 1-50 idle, 2-60, 3-80, 4-90, 5-110, 6-130, 7-150, 8-160, 9-170, 10-180-190max Most of the other posts cover broken parts that I just inspected/replaced. Any ideas what I could've missed or should I risk the drive and see if there are more symptoms? Thanks for any help you can offer.

forgot to mention, but with no shavings in the pan and to save cost I reused the torque converter, not sure if this could contribute to that.

I would drive to see if you have any other problems and go from there.
