Alternator or transmission?

I think everyone is saying the alternator because of the dim lights and it not turning over. Simple solution to solve it, use jumper cables and start your van. If the lights appear fine and it turns over without an issue, your alternator may indeed be at fault. Unfortunately, not being able to reverse may be an additional problem.

Thank you, Terry! I had the alternator and battery fixed/replaced and all is great again. I can now go in reverse. I guess the transmission wasn't getting enough power from the alternator/battery to want to go in reverse. Thank you again, I appreciate your help!

Are u serious I'm having the same problem

My 2005 Honda Odyssey won't move in reverse only moved like an inch & stopped & slips real bad in drive we changed the fluid also but still the same issues . Does this mean we need a new transmission?

Terry, my 08 odyssey doesn't work on reverse but I does go forward, the alternator it's bad, should I make reverse problems?? Thank you for your help, I'll be thankfully,
