*rolls eyes* Common issue, remove the transmission oil pan, then remove the shift linkage then remove the valve body. Their is a metal gear with notches well their is a spring loaded ball sometimes the metal gear gets loose on the shift shaft and then the balls pops out and well the transmission can shift out of gear. The only reason it jumps gears when the engine is on is because the transmission can't be shifted unless their is hydraulic pressure to shift. Anyways you just need to remove the valve body and either replace this small gear or sometimes you can hammer the tangs that hold it to the shaft. Very small part I forgot the name of the part with the some odd hundred parts in a transmission lol I think it's something like crows gear something like that. But this is typically what causes the transmission to jump out of gear also have a loose shifter. If you check all this and everything seems fine then report back to me and then we can talk about more severe problems.
