Do you have an idea on the maximum torque input for the AL80F trans?

Toyota doesn’t publish a hard “max torque input” number for the AL80F, and anyone quoting a specific figure is guessing.
In the real world, it’s less about a single torque number and more about heat, shift management, and how the torque is delivered. Smooth, controlled torque is what keeps them alive — not chasing a peak spec.

I get it, just hoping that the trans is up to holding the torque if we can keep it cool enough and if the pressure can be increased enough to keep clutches alive.

I would love to find a decent core trans and torque converter to inspect and check out for improvements/mods.

A transmission with a “shift kit” will last longer than a transmission in stock form. That cushy shift that every car has is actually more damaging. The clutches are slipping, which causes heat and wear to achieve a comfortable gear change. I prefer to feel my shifts. I found these guys a long time ago when I had my Tundra. I never pulled the trigger though. https://www.importperformancetrans.com/

yes that comfort is intentional slip. With tuning have full control of shift behavior for each gear, and each mode (normal, sport)
