I changed the oil, sensors, and solenoid. Checked wires and fuses. Restarted battery. Showing no codes and no lights.

Hi,

When you scanned for diagnostic trouble codes, did you scan the can-bus? CAN stands for controller area network.

Basically, all the different computers/modules are tied together via a few wires and communicate with each other. This type of scan will retrieve codes regardless of the module storing them. A traditional scan tool is most likely unable to do this.

Here is a link that shows how it's done:

Let me know. Also, let me know what sensors and solenoids have been replaced and what the vehicle was doing that led you to replace them.

Take care,

Joe

Yes, we scanned all the codes. The van stopped going over 40. Showed a code for solenoid. Replaced the shift solenoid and solenoid pack, shift sensor and ABS wheel speed sensor.

Hi,

If it is in limp mode, there should be a code or codes, so I wonder if we have something different happening. When you shift the gears, does the indicator show the correct gear? Were there any odd sounds related to the original problem?

Let me know.
