Tips for installing transmission?

right now I have no tranny in the car. the engine is in the car. its a built 318. i have a new TCI torqueflight 727 that i'll be bolting onto the engine. i've neve installed a transmission before and i have only a general idea of what i'm doing. pretty much just going to follow the service manual to get it done.

also the new tranny from summit didn't come with any levers or anyting on it. what levers am i going to need to buy? there will need to be some sort of lever for the shift linkage or something right?

is this going to be based on what shifer i decide to put?

thanks FABO members. any help is great
