Yes but you can't compare a honda tranny to a drag cars tranny. An auto will hold up to a certain point if taken care of and treated properly. Like Mteg said, no neutral droping and no sport-shifting, you should not downshift your auto, it will severly decrease it's life, the tranny is made to downshift on it's own and you will screw up the valves in there if you try to do it yourself. As for being strong, they're not, they're actually very weak, as i've stated before many times, honda trannys are weak like most import automatic trannys, they are not made for large power, they are made small and light, the plates and gears are thin and weak, not like domestic autos which are big and bulky and they have room to beef them up, they use heavier stronger materials, but they were also made to handle larger engines, V8's with more than 300hp. Your talking about a tranny that was made to handle 100hp maybe a little more but you get the idea, so yes the limit is small when your doing upgrades. I've seen them last to 200hp, but like Mteg said, you have to take care of them, a tranny cooler, upgraded torque converter, keeping the fluid clean, and making sure you run good fluid, preferably Honda ATF. They won't hold that much power tho, I won't put a max limit on them but I would imagine that 250 is pushing it and after that your going to be looking at rebuilds much sooner than usual.
