A 1997 dodge b2500 van has a 4 speed automatic tran but way is it on the inside your shifter only d 1 2 or no button indecator dash to tells you anything?

That's a common characteristic of older automatic transmissions, especially in work-oriented vehicles like the 1997 Dodge B2500. The lack of an indicator light and a limited shifter (D, 1, 2) means it's a simpler, less electronically controlled transmission. The transmission itself still has four speeds, but the shifting is managed internally without the driver having direct control or visual indication of which gear is currently engaged beyond D (Drive), 1 (first gear), or 2 (second gear). The transmission automatically shifts through the gears 1-4 based on throttle position, vehicle speed and engine load. The 1 and 2 positions are primarily for use in low traction situations or when needing more engine braking on steep hills.
