hello

I'd start by checking for worn mountings - check the tightness of the engine and gearbox mounts and their condition - this is best done by using a jack to take the weight of the engine off the mounts and seeing if any cracks or splits open up in the rubber.Also check the tightness of the mounts bolts

and I'd next check the gear linkage for any worn bushes or pivots as any lost motion means reduced effort at the gearbox and replace as necessary. Ideally have your assistant move the gear lever with you watching the linkage and see if you can spot where there is any excessive play or lost motion.
If its a cable type linkage check along the cable lengths for any damage or signs of heavy wear / fretting, if you find any replace the cable. There may be some adjustment on the cable tension at the gearbox end (depending on the year) and the cable should be tensioned so there is a minimum of slack but not so its taught
