First let me welcome you to IRV2. I see this is your first post. We are glad you found us. We have a great group of folks here who are most happy to help you with any questions.
I have a 07 Vue with a V6 engine with 5 speed trans. My manual states the following.
With the engine running shift from drive to neutral and let the engine run for 3 minutes and then turn it off. This procedure must be performed every 7 hours due to drain back of the fluid. In other words, if you tow for 2 hours and sit for 5 hours you must repeat the above procedure. Locate the large IGN fuse from the underhood fuse block and remove. I eliminated this process by hard wiring in a switch in the dash.
Warning; towing your vehicle after shifting from any gear but drive could damage your transmission.
My manual also says the 4 speed has unlimited miles at 65 MPH.
I would definitely check your manual as it may be different than mine.
Enjoy your travels & post often and keep us posted on your travel experiences.
