It is a 4-sp and an A-604.

Is there an overdrive button, on the console, to the right of the steering wheel, below the the rear window heater squirter button?

It is an A604 if there is one.

The '94 A670 in my GLH is a 3speed if that helps

The only computer controlled tranny in 94 was the A604. Not all A604 equipt vehicles had an "Overdrive" switch, non of my minivans have had it (89,93,94). Good luck rebuilding it, there is a large snap ring in the middle of the case holding one of the clutch units in. It is under a lot of pressure. A friend of mine who is a Chrysler technician tried one of these without the special tool and destryed the case.

that button was only 1994,1995 minivans. all 3.3 and 3.8 engines used 604 trans! 3.0 engines could come with either 604 or 670
