just started expiriencing a bad slippage while trying to accelerate. My truck will shift hard to second, and then the rpms will shoot up at about 25mph. Engine light came on as well. The truck popped the P0742 code for the [Torque Converter Clutch Circuit Stuck On]. Could it be a problem with the torque converter itself, or just the switch? I only have about 90k on my truck. With some towing through mountains. Its a 2004 1500. Any help would be appreciated. Ive searched for a while on the internet, and havent come up with anything worth sticking to.
