any manual transmission viehicle can be push started. I've pop started a tri-axle dump truck, with the help of a loader pulling it of course.
The higher the gear the more leverage the drive wheels will have on the engine. Too high of a gear and the engine won't turn fast enough to start.
second gear should be fine.
Usually it might take a few cranks of the engine during a push start to prime the engine to start. Usually it takes 2 tries.
