lDewey, welcome to irv2.com. We are glad to have you join us and hope to be able to help in answering any questions you have. The 3060 is a 1200 ft lb of torgue - the MH3000 is the same trans but with a little more torgue rating and longer warranty. the 4060 and the MH4000 are an even higher torgue rating I believe in the 1400 ft lbs range and again the MH version is the longer warranty. They all are six speed with dbl overdrive transmissions. I am sure you will enjoy the website and hope you will be an active participant of the forum. Good luck, take care and stay safe.
