Possible Causes:
* Worn shifter cable: The cable connecting the shifter to the transmission can stretch, fray, or become disconnected. This is the most common culprit.
* Broken or worn shifter linkage: Inside the steering column, there are various linkages and levers that transfer the shift movement. These can wear out, break, or become loose over time.
* Loose or damaged mounting points: The shifter itself might be loosely attached to the column. Screws or brackets could be loose or broken.
* Worn bushing(s): Bushings within the column help the shifter move smoothly. Wear can lead to looseness and sloppy shifting.
* Damaged shift lever: The lever itself could be damaged or worn at its connection point.
What to do:
1. Safety First: Before attempting any repairs, make sure the van is parked on a level surface, the parking brake is engaged, and the engine is off.
2. Check the obvious: Start by visually inspecting the shifter and the surrounding area. Look for any loose screws, broken parts, or obvious damage to the cables or linkages. You might need a flashlight to see inside the column.
3. Check the shifter cable: If you can access the cable (it's usually connected near the transmission), check for fraying, stretching, or disconnection.
4. Test the linkage: Try gently moving the shifter lever while observing the linkage inside the column. Look for any excessive play or broken parts. This will likely require partial disassembly of the steering column cover or trim.
5. Professional Repair: Unless you have experience working on automotive steering columns and transmissions, this is a job best left to a mechanic. Improper repair can lead to dangerous shifting issues or damage to the transmission. The steering column is complex and potentially dangerous to work on without the right knowledge and tools.
Important Note: A loose shifter can be a safety hazard. If you experience difficulty shifting gears, avoid driving the van until it's repaired. In extreme cases, the shifter could become disengaged, rendering the vehicle un-drivable. This repair typically requires specialized tools and knowledge.
