i have a transgo kit 727. if yours is a rear band apply starting in low should be ok. mine is full manual done by a local guy that had a record holding a body in the 60s. he said to do the burnout starting in first. do not get carried away with rpms. take it to second doing the same thing just keep them smoking and do not do a look at me burnout. when enough smoke let off the roll controle and slowly get into the throttle as it hooks to clean them off. never do a burn out in drive. keep rpms sane never do a dryhop. and stop before the line to pull it in low and roll in low a foot or so to set the sprag. he said do this and it will hold the power.
i know someone who busted 3 727s in someones hemi in a year being a jackass in the waterbox just like he runs his car doing a look at me tire fry and busted 3 gm 400s in his chevy.
do what you want or what makes you feel good but mine is the same trans since 1995. it gets a blessing every couple of years or a engine upgrade.
this is the first year i will have non stock parts with a billet front drumb.
