My trans has started to slip and its not throwing any codes. It only does it every now and then and some times when it does, i let off and it locks back in hard. I'm not sure if it's the torque converter acting up or something in the valve body. Only reason I say valve body is because I've pulled it out to clean all the bores and trim bores also. What would need to be logged to show me what's going on? This is what I've got setup right now. Anything else need added? I'll post a video of it slipping shortly.
