I have 2001 diesel 1 ton 4x4 with automatic transmission, rebuilt Trans with new torque converter about 15000 kilometers ago, this is my problem it will drop out of converter lock on an interment time this happens at around 55 miles per hour the cold reader said I had low voltage from three Tps replaced that also put in new camera sensor still doing through same time it feels like shuttle shifting but Trans shop said Trans is fine no engine codes has anyone had this problem and what is the Fix? THANKS
