Short answer - yes. It's called the Throttle Valve (TV) cable. You can pull it tighter for more line pressure, firmer shifts, holding lower gears longer.
Proper answer - Be careful with it. Too tight and too loose are both bad for your drivetrain. I think that too loose is worse than too tight, as the looser settings will cause the frictions to slip and wear out quickly. However, too tight could easily break things if you went too far. Per the Ford shop manual, there is a specified pressure that you want to obtain at the transmission test port with the engine running and a little tool (gauge block) mounted at the throttle body. From that point, it's up to you what you want to do with it.
The AOD has no computer control whatsoever, so the TV cable controls everything.
