Engine warmed up for at least a few minutes. Vehicle fairly level including side to side. Engine still running in neutral, ATF should be between the marks on the dipstick. Just like the engine the top mark is not the full mark. It is the maximum do not exceed mark. The symptoms she described are the result of in internal pressure loss. Broken seal rings on the direct clutch drum or a ripped piston. A competent shop can do a pressure test (in the Bentley) or drop the valve body and do what is called an "air test" We use compressed air to operate the clutches to see if one has obviously failed.

When I mentioned it to her, she said that the car had recently been doing a weird thing starting off. The engine would race, sometimes barking the tires when things engaged. At a stop sign, rather than keeping the car at the line on a hill, the slack in the transmission sometimes--randomly--lets the car roll back a few feet before it will "catch" again. I have never had a vanagon with an AT. What's the proper procedure for checking the level? The owners manual gives some detail but does not even specify whether the car is to be running or not when the level is checked. Anything else I should be considering? Jim
