Low Band Apply Question

A bone stock auto does not have low band apply unless you put the shifter in the low 1 position. Then the band is on. In the drive position the band is not on.
If that is what you have then I would always make sure your low/reverse band is correctly adjusted and only do a burnout in manual low 1. I would not shift out of that gear until the wheels have come to a complete stop. Then shift to drive and make your run. But that is still not 100% safe because during your 1st gear take off your tires could slip and regrip which shocks the sprag.
You really should get a manual shift valve body with low band apply.
This would have the band on any time the shifter is in first gear and it would stay on until you pulled 2nd at which time you are off the sprag. IMHO.
My ex partner has been building 727 and 904`s for 50ish yrs. , he built the "low band apply" fully auto. that is currently in my 505" 68 fastback. If I get on it burnout or not, the tires will not get any bite in low gear anyway, mostly second either, but will grab and hook up when it shifts to drive. I cant remember how he said to do burnouts ------going to have to call him.
