MPV won't shift

Hello All,

First time poster.

2000 Mazda MPV LX. 79K, A/T, 3.0L

Problem just started. Won't upshift or downshift. No speedo (electronic) and missing the pointer for the shift indicator. ATF is full, pink and doesn't smell burnt. I can upshift manually. And it only will downshift manually when stopped. Goes to neutral if I try to downshift when moving. I already changed the inhibitor switch because of the missing pointer on the shift indicator. It didn't help.

Thanks for any assistance.
