No 150 is not that hot for the gearbox. It will tolerate a lot more. It is entirely normal and expected for the temperature to rise and to get an input hot caution with a single pump failure and the throttle in the fly position, so the other indications are all linked. Normal actions require retarding the throttle on the side of the failed pump to offload the input. It can then be set again to fly for landing. It is, as quite correctly stated a "land asap" situation, not immediately as there is no immediate danger to the aircraft. The redundancy of double pumps has done its job and maintaining normal pressure, which is the most important thing. Pressure still at 49 psi is still in the green range. It is not a land immediately unless less than 5 psi and this will not happen if one pump is still working.
The crew did entirely the correct thing and did not prolong flight for longer than necessary and landed at the nearest suitable safe landing site.
