I agree with the other reply; take the vehicle to a reputable place to get the Codes pulled from the computer. Just slamming on the brakes doesn't cause a whole bunch of sensors to malfunction and require replacement. Don't fall into the "replace parts until it's fixed" method of repair. Get the actual problem diagnosed, then proceed with repair. Remember that all these components are related to one another and/or communicate via body control modules and network lines. A failure in one module can pull the whole related network side down. I'm not saying this for you to start purchasing body control modules, I just hope you see sensors within a car work together and communicate. Pull one down and it can wreck havoc on the remaining ones.
If slamming on the brakes caused such a stress to cause a brake fluid leak, I would start my diagnostics as to where the leak is. The leak is causing a pressure imbalance in the hydraulic lines, which again, causes various sensors in the brake system to send out fault signals.
In regards to the speedo, odometer, and check transmission message, I cannot offer input other than repeating that these modules rely on each other working properly. There might be a damaged module (or even just a module sending out a fault signal) causing problems on the network. The way (though as tedious and difficult as it may be) to diagnose this is to unplug each module one by one and recognize any differences in the way the rest of the vehicle behaves. Again, pulling diagnostic codes in the beginning will help narrow down the options.
Good luck. And stay away from the purchase-parts-until-it's-fixed method. You'll end up paying for a shopping cart full of good functioning parts for no reason except to drain your bank account.
