The top speed governor needs to be set higher, or set to "Infinite" or "Off", that's a PCM reprogramming kind of thing. As for how long tranny's last, they could last 10 miles or they could last forever. It all depends on how you drive, towing habits, whether it was serviced regularly, or just never did anything to it.
