transmission guys, need a little help

There are two different gears . Low and then first. If you pull out in low and shift you will get overlap as you call it. Try pulling out in drive (first gear) and before it shifts on its own pull it back to low then shift second . you'll feel the difference. Low gear select is low band apply. drive is first gear.

Uhh, NO. There are not 2 different low gears. The only difference is when you pull the shifter down in low it applies the rear band. That happens anytime you pull the shifter down in low at any speed. If you pull out in drive then pull it down into low it applies the rear band so it'd still bindup/overlap.
