Not really, for 3 reasons.
1 - Engines and diffs are much hardier devices, they can go for much longer with out giving a thought to correct maintenance.
A diff in particular can go for several hundred thousand k's without breathing on it.
Engines only need a good sniff of oil now and again and they'll run for the same time.
Engines have been known to run for many years with out ever having an oil change, just top ups
Try that with an auto tranny sometime.
2 - Most people will do something about the engine, because we are more programmed to provide a good life blood for our engines. Transmissions are much more ignored, partly because the transmissions generally can't be serviced by the home DIY type (much to do with not having a dipstick), and secondly because they just continue to run without any problems right up until something serious goes wrong. Engines can often make odd noises which the owner will hear and have looked at. Or it will start missing and need plugs and/or leads. It is often a cheap fix at that point.
3 - Whilst an engine is more expensive to replace than a transmission (new or reco), it can most often be repaired quite cheaply. Second hand is also a good alternative with an engine as it is easy to bench test, whereas it's virtually impossible to bench test an auto, so can be unknown as far as second hand.
And diffs are just not that expensive. A full reco can be done for $1000, drive in - drive out. You can more than double that for an auto tranny.
