My RV has a 6v92t and V730 xmission with 275,000 miles. On the hiway it suddenly shifted from 3rd lock up to I think 2nd lock up. I was going 65 MPH, it slowed to 55. After I stopped it would only go to 2nd no lock, 37 MPH. I was towed to the nearest small diesel shop and told the clutches were gone, fluid was brown. They put in a take-out unit from Nimco in NJ. It went 13 miles and then did the same as the original xmission but the fluid is bright red. The shop says they don't know what to do, I should take it away. They charged me $4050 but that's another problem. Do you have any suggestions about what might be wrong and how I can get back on the road so we can get home? Thanks.
