Difference between NP435 and NP445?

Can someone please explain the differences between the NP435 and NP445 transmissions?

This is in a 1977 Dodge 4X4 pickup but is not the original tranny.

Thanks!

Thanks for the reply.

I would like to be able to determine which transmission is in my 1977 Dodge 4X4 pickup. This is not the original transmission and I don't know what it came out of. I just purchased the truck. I do know that the Dana 60 rear and Dana 44 front axles are out of a 3/4 ton.

Is there a way to find out what transmission this is? I need to buy some shifter parts.

I cannot find a single picture of a 445 but found info stating it was in 74-80 Dodge 2 and 4 wheel drive trucks.
