I have a 2005 Honda Odyssey, she was working fine. Then she started dropping gear and my idle was going crazy. The D light started blinking. Took it too a auto shop and it gave me a P0747 code? So we change the solenoid dual and single linear but now she only shift into 1st gear and struggle to reverse or sometime won't reverse at all. Please help do I need another tranny?
