Mike, 1.) To me this is likely what occurred here. When you were driving it, all of a sudden the issue with it revving up and down is because the engine protects it self while in drive and reverse from revving to high. The engine computer limits engine rpms and when it hits a limit the ecm will kill the fuel and let it rev down to reduce the speed so it does not blow up. Us technicians call that the rev limiter. So when you were driving something lost the drive to the transmission likely causing that to disconnect the torque converter from connecting the engine torque to the transmission. 2.) Wont move, but someone said your oil was overfull. When transmission levels are checked they are always done in park, or if you consult the owners manual it may also say neutral with the Ebrake on. Regardless if you checked the transmission level and it was overfull it is likely something is not making the pump spin. The torque converter is bolted directly to the engine, and on the back side of that is a 2 teeth hub. Anytime that engine is spinning because the converter is connected to the flexplate of the engine, it spins a oil pump in the trans. That oil pump drops the level to the oil dipstick you check when it is running properly because it pushes the trans level to the parts that are responsible to make those gears occur it also circulates the trans fluid to the converter. All that drops the level to push it to the cold or hot range depending on the temp that your checking it. And there is a level on the dipstick to tell you that. Always check dipstick 3 times for consistency and always go with the lower fluid trace when doing so not the top one. If the pump broke or something internally to the pump gear broke no fluid can be pumped from the filter to pull it to the transmission oil pump. This would raise the level in the pan and when you check it on the stick to someone who may not know that, appears to be overfull. If you dropped the level to the normal range it means it is likely underfilled. To check that, check the level with the engine off 3 times for consistency... then start the engine in park and recheck the level, in EVERY case, it should drop EVERYTIME... if it is not the pump is not rotating and is not pumping pressure to the transmission converter and clutches to make it move forward. If this all of a sudden did that like you say depending on the severity of it, it may have not damaged your transmission internally as far as clutches are concerned, but the pump rotor sure seems like what possibly broke to me which is why your vehicle did, what it did.
