Van won't go into D2, cna you tell me why?

Maintenance/Repairs

I was attempting to put my van into D2 to get up a slippery hill (not even sure D2 was the best option). I drive an 02 Honda Odyssey van. It would not move to D2 before the hill, nor once I was in my garage on flat ground. I had the tranny replaced last summer. It has 148,000 miles on it. Do you know what is wrong???

Transman18 will be your answer for this. Hopefully, he’ll be around.
