Basic rule of thumb on transmission long-term surviving towing with compact SUVs:
If you have any vehicle with a CVT like Honda CRV & thinking about towing or hauling, just give yourself some breathing room from an instant-destroyed transmission, trade it in for another compact SUV with a clutch-plate automatic. CVT towing CAN be done, but the same way that you could travel 5 miles across a 1 foot wide ledge on a cliff.
(#1 would be manual transmissions if someone still made compact SUVs with them)
( I would put "mild hybrid" as #2 but they only exist on pickup trucks & large SUVs like Chevy Tahoe, Ford F-150 & RAM 1500 hybrid, which is electric-assisted clutch-plate transmissions)
1) clutch-plate automatic (Toyota, Ford, GM, FCA, etc ) - toughest towing in stock factory form
2) hybrid-electric - can be upgraded to tow heavier loads over short distances or slower speeds than clutch-plate.
3) CVT automatic (Honda CRV, Nissan, Subaru SUVs) - make 1 mistake, your tranny is unrepairable
Yeah this is gonna upset some people but it is what it is.
The CVT automatic is lighter than the other 2, cheaper to make, & is capable of infinite gear-ratios to theoretically set a perfect fuel efficiency ratio for engine rpm - unlike clutch-plate automatics which can only pick from 3-5 gear-ratios max.
So CVTs win the #1 clutch-plate tranny on cost, weight, fuel-efficiency -- but they are a comparative HORRIBLE design for towing or hauling anything heavy.
While clutch-plates rely on a hydraulically clamped clutch-plates & disks that are either clamped or unclamped not slipping, CVTs get all their torque from just the grip of a belt in-between 2 metal cones & the cones move in & out, in is squeezing the belt to the cones outside for a larger "gear" ratio, out is letting the belt drop to closer to the center of the cone for a smaller "gear" ratio.
So the belt is by design, slipping on the cones during "gear-changes" which is continuously as in "Continuously Variable Transmission" but only just enough to not be spinning on the same part of the cone.
CVTs can about last forever with proper fluid changes & keeping the loads & throttle use within design limits, however if you stress a CVT too much to wear the squeeze of the pulleys isn't enough to grip the belt & the belt slips & spins under load, it basically cuts grooves in the pulleys & at that point the CVT cost more in parts & labor than a new one & is scrap.
Clutch-plate automatics can typcially tow above their ratings without wearing out the clutch-plates, at slow speeds, and if you do overload a clutch-plate automatic towing to heavy a load so the clutch-plates slip, it simply reduces transmissions remaining life before a rebuild, & clutch-plates are cheap its economical to replace worn clutch-plates in a transmission rebuild .
If you overload a CVT & the belt slips & spins just once, you have wrecked your transmission, not worn out for a rebuild, wrecked. CVT's have a protection torque-sensor that hydraulically cuts power to the CVT to protect it, this may or may not work as expected so don't count on it, you can get away with a lot more overloading a clutch-plate than a CVT.
Then there's hybrid-electric, which is similar in operation to CVT trannys for infinite gear-combinations for fuel efficiency, but unlike CVTs they "couple" or connect the drive wheels to motor through non-contact electric fields instead of mechanical pulleys & belts so no pulleys to "wear out" from slipping.
Electric drives provide massive instant torque they should be amazing for towing then, the problem is that electric drive systems are much more sensitive to high heat than other systems, & while occasional quick high torque electric loads dont generate much heat, over time the heat-load increases exponentially as heat causes more resistance to pulling the current so voltage drops causing higher current draw which generates more heat exponentially which will destroy motor windings & inverter components in very short order. Any type of high torque load for more than short durations requires a massively oversized cooling system.
Side note this is why the "mild hybrid" or hybrid-assist of using an electric generator-motor to assist a clutch-plate transmission is currently the most common hybrid-electric towing system
