rebuilding tranny, wat needs to be done?

[dino179]

wasup everyone, yesterday i bought my first svx (we had one before but it was my dads.) i bought a 92'dark teal LS with 114,000 miles and a bad tranny for $1000. i got some tranny shop to rebuild my tranny for $800. what i wanted to know was what should i do during my rebuild? im going to put an aftermarket tranny cooler in and im thinkin of a stage 1 shift kit, but i heard something about flushing your radiator and changing all your hoses..??? HELP!!! whats all that about and what else should i do to ensure a long life for my car and my tranny/

thanks
