Hello,

There are absolute maximum values given in the datasheet of mosfets for the Vgs voltage.
Going over this value, the mosfet will likely not survive.

Post a schematic with all the details.

is the mosfet gate damaged if it clamps to ~40% more than Vgs rating?
Most likely.

transients are typically short.
Any allowable overstress from transients will be listed in the datasheet. If it isn't, then you should assume that it isn't allowed; or contact manufacturer to see if it's characterized.
