Transmission Range (TR) Sensor

DESCRIPTION
The powertrain control module sends a voltage signal to the transmission range (TR) sensor. The TR sensor incorporates a series of step-down resistors which act as a voltage divider. The PCM monitors this voltage which corresponds to the position of the manual control lever (P. R. N. D, 2, 1). The TR sensor is located on the outside of the transaxle at the manual control lever. The function of the TR sensor is to determine desired gear and EPC pressure. The TR sensor also contains the park/neutral and backup lamp circuits.

SYMPTOMS
Harsh engagements and firm shift feel. No 3/4 shift. May downshift to a lower gear. No rpm rev limiter in PARK or NEUTRAL.
