Auto-X strategy with a TH400???

[atomicjoe23]

I've driven a couple of auto-x events, but only in cars with a manual transmission. . .

. . .my '67 Pontiac Firebird currently has a TH400; what would be the driving strategy for auto-x with an automatic???

I don't know much about automatics. . .in fact this will be the first car I've had with an automatic transmission. I would think you wouldn't want to have it in D and have it hunting around for the right gear or shifting up/down at inopportune times.

Start in 1st, shift manually into 2nd and then leave it there just like a manual??? Can you do that with an automatic without a manual valve body. . .to my knowledge this is just a stock TH400. . .

Thanks for helping out!!!
