I have a c4 built by Jay at Broader performance. Was built 3 years ago but was just installed a couple of months ago. Once at operating temp the 1-2 shift will hang till late in the rpm' during normal easy driving. Take off in D and it will stay in 1st until I stomp the throttle then it will shift to 2nd and shifts to 3rd as normal with no problems. If a don't stomp it, it won't shift into 2nd, it will stay in 1st at 3000 rpm's all day until I stomp the throttle then it will shift into 2nd. If I manual shift it it will shift great. It's not a modulator adjustment issue. I tried that. It will just make my 2-3 shift change but 1-2 is still hanging. Anyone have any idea what would cause this?
