Hi i have a 98' Mercury Mystique GS V6 2.5L duratec engine. I noticed the other day while driving on the highway doing about 120KM/H which is about 80MPH. Once the car goes to 3000 RPM or more it starts to kinda stall I recently changed the spark plugs could that have anything to do with it?

Why do you think it is a tranny problem? Did you gap the plugs 0.054 inch? Check/change air filter and fuel filter if necessary. Also check the IMRC, if it bogs down above 3500 RPM or so, it could be failing. Might want to try and save it by relocating it. Any CEL codes?

Does the tranny have its own computer?
