I think your asking "can an automatic be push started?" The answer is No, a manual transmission can be push started by popping the clutch. ...

Rob, assuming this is a 4X4? Sounds like a bearing. They can vibrate, snap, clunk, all kinds of terrible noises or vibrations.
Axle u joints will also do this. Is it all wheel drive?

You have a leak and you have air in the system. More than likely the slave cylinder is leaking, the slave is a direct acting one and as with all direct acting slave cylinder it is located inside the transmission bell housing on the transmission input shaft collar. The transmission must be removed to replace it.

The only fix for a manual trans, is to replace the clutch

If the vehicle is almost brand new,then you diagnose
throw out brg & hydraulic system

how old is the clutch and who else do you let drive it?? inspect all pieces from clutch pedal to the clutch it's self. never speed in reverse!

The problem is in the transmission with the shifting mechanism or possibly with the linkage. I would suggest that you take it to a transmission shop. This can be a big job .

It sounds like your clutch may not be releasing full. Does it shift easily if you match the speed of the engine and transmission shaft closely? Does the clutch feel normal?
