OBD 2 Codes

[JJAB]

I am having an issue with my swap. When driving the vehicle, it shifts out fine until you get to fourth gear going into overdrive where the truck then begins to jerk constantly. This only happens going from fourth gear to overdrive. The code retrieved is P 0357, Malfunction/Ignition Coil G. Once this code pops up , the truck does seem to run a bit rough, almost like it is missing or misfiring.

FYI:

C12 is hook to the brake switch as it should

The 4L60E is newly rebuilt with new tourque converter( Actually this is second tranny because I had tranny builder go back through it because I thought it was a tranny issue)

Cylinders 5 and 7 both have new coil packs.

Any help would be appreciated!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
