What I’m not understanding though is its an intermittent problem. If it we’re clutches, wouldn’t I lose 1st all together? It sill works perfect when placing it in manual mode. Remember, I’ll start to accelerate under moderate throttle and it will go into neutral at around 1,200 rpms, too early to be going into 2nd.

It almost feels as if the pressure relief valve is opening and dumping all the line pressure. Or it’s beginnging to duty cylce and just dumping. I’ve done stall tests and it holds around 2,200 rpm. I’m going to hook up a scan tool and see what the Tcm is interpreting from all this when I have a chance.
