Transmission / ignition switch interlock? slips gears

it is very common on these that the elect part of ign switch behind key and tumbler goes bad and causes all sorts of pwr issues

If you can afford to purchase another vehicle, don't waste you money on the honda.

The 'interlock' recall was simply put- to keep the key from coming out of the ignition switch when not in ''park'. That has nothing to do with the electrical portion of the ignition switch function. If the trans is slipping while driving , then first check the fluid level(car off ,on level ground). The other problem they did have was , as stated , with the electrical portion failing and most commonly causing a 'stall' condition. If you still suspect an electrical problem , and the car is in good enough shape , to be worth it to you, then have the trans 'scanned' at a dealer and make sure they give you the codes (specific) and post them. One other thing to watch for is if the 'D' light flashes at all when symptoms occur , that would be a deffinite indication of trans problem and that codes are stored (not necessarily turning on the check engine light).
