True to a point I guess. However, the greatest majority of your "average" people take great trust in them. They have been around for decades. Just input. No need to get defensive. Sorry
I'm sure any of the shops here can install a tranny for you. Even your local neighborhood mechanic could do it if you have someone close by. A transmission install is fairly simple. If you're really in international falls I would just find someone local vs towing it all the way down here.
I would start a new thread with some details on your car/tranny/location etc. Most people are checking this thread are thinking it's about finding a tuner. You may get a few more bites with a transmission specific thread.
