I have a 98 Monaco 40 ft. 350 hp Cummings that is 1 month old to me. On a trip south, after 2500 miles, the transmisson down shifted to 4th and would not shift up or down, N or Rev. I limped to a dealer where the tech could not get his computer to read the trans codes or find the problem. He then shut down the motor and it went to N and could be restarted but the trans selector stayed in N. He then shut down and replaces the trans selector box with a used box he had in his tool box. I test drove and all was well, and they let me keep the spair box to get home, 700 miles. We made it home to MN and the weather turned cold, 0 to -15 at nights. I had to move the RV 4 days after we got home and after I got it to start it wound not go into any gear. I switched the shift comtrol box to the orginal one and I backed up once and went into D then to N and now it will not go into any gear. I disconnedted the chassia battery to reset the unit but still no getting to R or D. I tried the borrowed box with no luck.
Please help me with info on how to trouble shoot and fix. The throttle does not work either. Thank You RB
