    OK good! While you're checking the trimmer valves, also take a look at the trimmer regulator. also take a look at the trim boost accumulator if it has one.

    I have a 1993 Pace Arrow 250hp diesel with MD3060 transmission and have almost the same problem. Has anyone had the same issues and if so, what was the fix? Any help with this problem would be appreciated. Thanks

    After reading about several people having this same issue, I was fairly sure the trouble was in my ECU. It turned out that was correct. I sent the ECU to Transmission Instruments in Flower Mound Texas 1-866-439-9779 and had the ECU repaired. They did a great job by the way. I got the unit back, installed it and yea! fixed! Thanks David V
