Many here might be able to help with vehicle diagnosis issues, but for magnitudes more help...
If you want to get serious about finding answers and finding people who have had the exact same issues then find a DODGE Van or truck forum!
There is absolutely nothing unique about a transmission on an RV compared to the same transmission on the same chassis in the regular van or truck configuration. The RV is just built on a stripped down van chassis.
Vans and trucks often use the exact same motor and trans.
Truck guys on a truck forum will be more likely to know and help you, they are way more likely to be mechanics than van owners, and the truck forums are more active.
You should be able to just browse a truck or van forum for Dodge and find the answer has already been discussed.
Camper forums will be helpful for camper issues like toilets, batteries, roof leaks and such. Go to a vehicle forum for vehicle issues.
