i have a 2000 gt with the 4r70w aod, i have completely redone the entire suspension and the motor is currently out,the cradle and motor are ready to be put back in but im waiting on my tranny.would it be easier to wait for the tranny and put them in together or just do them seperate? oh and i have long tube headers also,wondering if they will be in the way if i do it seperate....thanks for all and any help.
