Help! Im about to pull out my tranny!

[lutzy]

Hey..So I just bought a 1969 camaro and it has a TH400 in it..I bought a 5 speed setup I plan on putting in..So I was hesitating on having someone doing it for me but kinda short on money so im gonna give it a try. I have the car all jacked up so far and looked everything over. I have the cooler lines running to the radiator. Do I disconnect one of those lines to drain the transmission? I dont see any drain plugs..please I need some help! thanks
