93' Camry Le

I have a 1993 4-cylinder, automatic Camry Le. We just put in a new tranny, filled the tranny fluids, but now the Camry won't drive. The engine turns on but you can't put it in drive or reverse. Was wondering if we missed something or what the problem could be. The tranny was bought from a shop and we were told it was in working condition, it has 100,000 miles on it. Please help with any useful comments.

are you sure you installed the shift cable correctly? it leads from the gear shifter to the transmission.

And added the correct amount of fluid? Check the fluid with engine idling, in park (neutral for dodge) with warmed up engine....
