Hey guys. I have my 4l80 in my truck with a 3200 circle d converter and transgo hd2 kit. I've got roughly 5000km on it and it decided to throw a p1810 and p1870 code today. When the tranny shop did the shift kit. They put a shift control manifold in while they were there. Been reading that sometimes these codes will come up if it sees too much slippage. But would that be caused by the converter? Can the computer actually differ between converter stall and slippage? Is there a possibility of my converter being pooched already? Or maybe a chance that the shift pressure manifold is actually gone bad after 5000km? Fluid is still red and clean. It was down a tiny bit. But no more than half a liter and its topped up now. Truck puts itself into limp mode until the engine light is cleared. Any ideas?

It was tuned after I made the switch from 4l60 to the 80. Stock 4l60 to stalled 4l80. There were a couple codes in that were shut off because it would send max line pressure to the shift and try to send you through the windshield. Would it be a safe move to have these two codes pulled from the computer? Just doesnt seem to make sense that it would do it after about 5000km
