A few days ago our Ultrashift transmission started acting up. It would not go into gear at times either up shifting or down shifting. We had to pull over on the side of the road and shut our battery switch off for 2 minutes to get the transmission to reset. This went on several times for about 24 hours. A driver told us that most of the Ultrashift problems were electrical. He told me to spray WD 40 on the battery terminals. Since there was nothing to lose by trying this I did. And the transmission has been working fine since. 3 days and 1800 miles with lots of shifting in the northeast and the mountains between Connecticut and Florida. (Today I pulled the battery cables off and cleaned all the connections until they were nice and shiny.) I plan to take it to the shop Tuesday to have it checked out. Is there anything they can do if it is operating properly or am I just wasting my time and money?
