The main problem is the rapid wear of the clutches and especially the torque converter.
Vibrations caused by wear of the GTF clutch break the oil pump bearings
Further along the chain, the oil pump itself and the planetary gearbox are usually destroyed
Wear products clog the valve body solenoids and there are shocks and jerks of the automatic transmission
The electrician delivers a lot of trouble, the speed sensors are buggy and the wiring burns out
