Lincoln, North Dakota | They have both been proven to be reliable transmissions. Syncros can go out in the quad but its not a hard job to fix. The most expensive problem is if you have to repair something on the bottom shaft. Remember the Range shift ABCD is not synchronized and requires coming to a stop before shifting. Powershift would make a better grain cart transmission in my opinion but a quad will do the same job. Worst part of the 8 speed is that 3-4 shift and speed change. That transmission would have been great as a 10 or 12 speed. We have a 4430 with north of 10,000 hours with a powershift that hasnt had much work done to it. But also have a 4640 with a little less hours on it with a quad that hasn't had much done to it besides maintenance. I like either transmission haven't found much that either wont do. my .02 | |
