I am reaching my boiling point with all these so called Diesel Specialty Shops and Transmission Shops selling a bill of goods.
I don't care if it is DTT, HTS or any number of other so called "Custom Transmission" specialist.
Here is the truth. I have tried the best of the best and still find that they are not much better than a stock transmission. Billet steel all the way through and built VB
's, while the manufacturer of these transmissions claim to be able to handle 800+ HP and more, the truth is they don't stand up to a real work truck. Put 19,500 pounds behind any of them and they fail... Only difference is it cost a hell of a lot more to replace the "Custom Parts" than it does stock ones.
I am not saying these transmissions are not better than stock I am however saying they in no way hold up to the reputation these manufacturers are claiming.
Why is it Cummins can make a truck that is not scheduled for a rebuild for over 300,000 miles, but finding a transmission that will hold up for 300,000 miles is impossible. I realize that maintenance such as clutches and such must be replaced, but input shafts, pumps and etc.. should last if they were as good as these companies claim. THEY DONT!!! If there is a company out there that thinks they will, I challenge you to put one in any of my trucks. We do about 180,000 miles a year, run around 600 HP at all times, and use them to work hauling trailers. We don't beat on them, but we do demand them to work and work hard.
Share your transmission stories here and lets find out who really is best. I know lots of Great parts, and have met lots of great people who genuinely think they are great, but truth is, they don't know the real life situations..
