I will start off by saying that this is my first Range Rover but not my first Land Rover. This one in particular giving me a lot of issues. Im pretty sure that i have corrected everything except a vacuum leak and some transmission issues. I have the 4.4 in mine and can not find a good vacuum diagram for it. I have done the valve cover gaskets, MAF cleaning, cleaned throttle body, new air filter, new plugs, but there are a few vacuum lines that i do not know where they go. Also, my transmission will only shift from 1st to 2nd and 2nd to 3rd without shifting into neutral first. I have drained and put new fluid in to see if that would help. It did not. Do i need to do the filter or solenoids?

Any help would be greatly appreciated
