We have pulled all the connectors apart and cleaned them, they didn't look bad at all just a little green dust build up.. we are still chasing it today.. checked vacuum lines, found 1 broken, fixed it, no change.. tho today I felt overdrive take over at 80 km per hr.. foot on the gas with a low idle.. then minutes later it's back to no overdrive, high rpms at 80km per hr.. I am going to add some Lucas trans stop slip in the morning and drive to my Grandmother's celebration of life.. some chance I may see a change for the better..
It took an automotive electrician5 days to find mine. I have the exact same bus as yours and discovered this issue is common. You might also check all the wires around the engine as I have read of others having the issue and discovering an issue with wiring on the engine. My bus had a new transmission so it was ruled out. You have the exact same issue I and others described.
The intermittent running well followed by the overdrive issue making it feel like the transmission is slipping. The first thing I did was have a transmission specialist look at it and he confirmed there was no issue with the trans. After the electrician fixed the wiring I've had no more issues with that.
@@themightydonallan Keep another fuel pump with you as the pump in the tank has a tendency to go out/have issues which causes vapor locking. Which is another common issue with this bus.
@reggieh1372 right you are!! I literally spend 5 weeks battling fuel pump and sending unit in the spring of 2023 driving across Canada and back.. changed both out when we got to medicine hat alberta.. fingers crossed that I am not gonna have to deal with that nightmare again for a while.
