Has anyone had shift solenoid malfunction B code come up with there engine light? Also has anyone replaced this part on there van? We bought a book but it doesn't show how to replace it or exactly where this part is. If anyone has done it your help would be greatly appreciated!! We bought this van about 45 days ago and not very smart of us with no warranty and they only offered a 30 day warranty. The dealer said they did not touch or change the transmission fluid, because that is one thing I read to make sure that you use atf+4 in there. So I am not sure where to go next with it.

Tranny shop to get it diagnosed. They will be able to tell you what action will be required to fix the problem. This really isn't a diy job.
