Okay I'm too curious can't take it anymore...odd valvebody?
So I've noticed this pretty much since day one of owning my '87 Vic winter car. It naturally has the same sequence on the shift indicator, PRN(D)D1. However, moving the lever to "1" holds 2nd gear *no matter what*. I was shocked to find this out. Even from a stop, it will stay in 2nd. I guess this would be a way to keep traction in the winter taking off from a stop (it does of course help a little)...but my friend drives an '89 Grand Marq and "1" indeed holds 1st gear as my cougar does, and then of course 2nd if you do that trick.
....It's gotta have a different valvebody, no? Anyone know of other examples of this happening with an AOD? An option maybe? I keep forgetting the name of the valve the shift lever moves, the Baumann kit manual tells that all but I forget where that went. Maybe all you would need is a different valve to direct fluid differently through the passages it comes directly into contact with seeing as you can do that hold 2nd trick.
