2004 2500hd Sierra

I will drive about 3 miles then it feels like it falls out of gear and stall once it died and threw a code(p0700 I think it was) but haven’t got it since then. It will die if you don’t press the throttle down but it won’t throw a code. It has 220,000 miles. Replaced the filter head, batteries, and the cp3 sensor. What is wrong with it we need to get it to work please help thanks.

The P0700 is a generic code telling it to set the MIL, need a better scanner to read the other tranny codes that it should have also.
