This problem gives a cascade of faults, besides the PTU lost communication with the DTCM I was getting ABS faults, transmission faults. After it would give me the fault it would clear itself but the BCM would still have these other pending codes, this made the transmission really sluggish. Since I replaced the module it feels like a completely different car, after stopping at a stop sign it accelerates without the first gear banging it would frequently do.
