I use spray lube from the top. I have noticed later coaches don’t have these and I wonder if they are even needed?

I talked to Allison about the dip stick level check and he said the only level indicator they use is the electronic one. They have no idea how the manufacture located the tube. You might drive up a big hill to get the remap up and the find a level spot with the coach level and run the check. 

Howdy, We had something like that and it ended up as a leaking exhaust manifold gaskets and an intake boost sensor bad. Repaired by Crosspoint Cummins in Knoxville, TN and has run perfect ever since. 75,000 miles then and now is around 130,000 miles.
