2014 Silverado 5.3 4x4 P06DD code

Hello,

I have a 2014 Chevy Silverado 5.3 4x4 158k on the clock. Torque converter was going out so I replaced that. Everything was going great then I noticed my oil pressure would rise to almost 70psi on acceleration. Upon stopping at a red light in gear it would drop to about 17 psi. CEL triggered and P06DD came up. I replaced the oil pressure sensor, oil pump and solenoid harness. Drove it around for like 3 days and CEL came back on. Anyone ever run into this issue. Just curious before I dump more money into this truck..
