Usually, if an auto is beginning to slip, you might expect to see rpm flares when driving, especially when changing gears. A standard torque converter would usually stall and drive through the brakes at a fairly low rpm (like 1250 to 1500) if the trans is slipping you would likely have higher rpm and not feel the vehicle pushing forward hard when stalling the torque converter. Also worth checking the fluid condition and level (usually check hot and in drive) If the fluid is dark /burnt and / or low, this is a red flag and can cause issues with shifting and possibly clutch/band slip. Any noises or harsh shifting would also suggest the auto needing attention. Hope this can help!
A240L Toyota transmission. Is It's torque converter upgradable?
Not anywhere I can see, only option would be to replace with an aftermarket unit like a high stall, if one exists for the A240 series
how can we test if torque converter slip or gearbox slip
