What are the three sensors on 1999 Dodge 1500 van transmission?

A 1999 Dodge 1500 van's transmission doesn't have three sensors in the way a modern transmission might. It's more accurate to say it has several sensors related to transmission operation, but not a specific set of *three* that are universally considered the primary sensors.

The most likely sensors you might be interested in (and the ones most commonly replaced due to issues) are:

1. Transmission Output Speed Sensor (OSS): This sensor measures the rotational speed of the output shaft. It's crucial for the transmission's control system and for the speedometer.

2. Vehicle Speed Sensor (VSS): While not strictly *on* the transmission, it's closely associated with it. It's often located near the transmission, and its signal is used by the transmission control system (and other vehicle systems).

There isn't a third consistently essential sensor directly on the transmission itself. Other sensors, such as ones related to fluid temperature or pressure, might exist depending on the specific transmission type (e.g., 46RH, 46RE), but these aren't universally present or considered core sensors in the same way as the OSS and VSS.
