Our 2005 TN75 with only 460 some hours is having some issues. I wont go into detail on all but the glow plugs are not functioning, should be simple fix. But the main issue is the shuttle is not working correctly. It will flash a sequence of lights(red in center of dash) the sequence is as follows, *1 pause ***3 pause ********8 and then it will start all over. It will not move until the light flashes. The length of time will vary, warm weather 1 minute is a good guess but now that the weather is colder it takes much longer. Today is took about 20 minutes from the time it was started before it would move. From reading and studying some wiring diagrams I believe the issue is a fluid pressure sensor on the trans. Any help would be greatly appreciated. Thanks in advance!
