Ram tranny problems

What actually controls first gear that different from the rest? I've always seen cars losing multiple gears and not just one. I'm trying to understand how it works instead of just slapping stuff into it. Anyone can throw plates and a converter in. Could the regulator/govener sensor be bad? Could it be because the abs and the computer not realizing the truck is moving until 20mph causing it not to grab first? Sometimes it the simple stuff that's gets you.

Here's the mechanical sequence:

1st gear--only the rear clutch is engaged when you have it in drive. When you pull the shifter down into manual low it applies the rear band along with the rear clutch.

2nd gear--The rear clutch is still engaged just like it was in first gear but now the front band applies and if you were manually shifting it the rear band dis-engages.

3rd gear--The rear clutch and front band disengage and the front clutch applies.

I don't know the electronic units so I can't say what's happening there but you could be right about the ABS sensor causing a reading that's confusing the computer. Before I did anything else I'd replace it. With these new electronic unit's any one little thing can goof them all up.
