[lightning bug]

I've seen some of Bergman's engines and a GEX trans. The engines were brought to my friends shop to be rebuilt because the engines failed in only a few hundred to no more than a few thousand miles. Another friend of mine has a GEX trans that is stuck in second and was only in his bus for a week. No it wasn't driven hard. Don't let the pretty colors and flashy ads fool you. You're basically buying assembly line parts. My opinion is for you to find a builder you can work close with and you can trust. By the way neither Bergman nor GEX wanted to help these people to resolve these problems. So find someone who will stand behind their product also.
