I'm glad you survived. You need to flush your ATF and replace it now, though. Once you hit 230 you oxidized it and now it's going to degrade very, very rapidly and not protect your transmission or perform as well. Go to a good shop and have them drain the whole trans (not just the pan) and put some high-temp full synthetic in (I use RP). Helps keep temps lower and oxidizes at a higher temp to give you more of a buffer. If you haven't already put a larger ATF cooler in your rig, having one installed at the same time you're swapping fluids is a good idea.
