Thanks for the info. Liberty promised that it was a unknown problem when I brought it to him and he would get it fixed. I tried multiple iterations of shift dog counts (all at my expense, I might add) and all it did was make matters worse. Actually, the highest shift count achieved was with a 3-dog setup that Liberty said would never work but it was the only one he had that I hadn't tried. I tell you this so you won't be drawn into their revenue machine when the 4 speed begins to have problems. My trans were both built with 5-dogs; he had me try 6 and when that reduced the shift count by almost 30%, he suggested 7. I requested 4 and the answer was, he didn't like making those because that's what his competitor used and I already told you the 3-dog story, but I insisted on the 3 and, somewhat, improved durability. The "company" line was that the original design had 3-dogs (5 speed trans) and Greg Anderson requested they try 5-dogs to reduce maintenance frequency and they switched all production to 5-dogs, based on Anderson's satisfaction. Again, the results are based on 5 speed applications in an ultra-light weight combination. The racers using 4 speed trans will all tell you (if truthful) that the two trans act like two, completely different, parts based on the ratio drop benefit derived from the extra gear and starting line weight of the application. The almost unbelievable fact is that, as a driver you can actually feel that the 3 dog setup shifts easier and quicker but I've only used it on 2nd and 3rd speed. No need for 1st and 4th is completely different animal and pretty reliable at 50 to 65 shifts before needing service. Breaking any internal part is almost none existent but 4 speed dog wear can be an issue. Good luck.
