Not sure that the above would suit the style of an engineering exam paper; a tad colloquial perhaps?
I think you'll find that the a/c hangs on the transmission, not the other way round, and there is a fifth mounting at the rear of the casing. As you say, the actual lift loads are passed through the lift link to the lift beam and then into the longitudinal I -beams. No idea where 'your' a/c is; slogging away in Nigeria no doubt and approaching the 30,000 hour mark.
