Transmission Temperature Sensor - Fault Code
NO: 08-06-95GROUP: Electrical
DATE: Mar. 3, 1995
SUBJECT:
Transmission Temperature Sensor - Fault Code
MODELS:
1994 - 1995 (BR) Ram Truck
NOTE:
THIS BULLETIN APPLIES TO VEHICLES WHICH ARE NOT EQUIPPED WITH A TRANSMISSION COOLER (SALES CODE - NHB).
DISCUSSION:
If the ORB gives a fault code "Trans. Temp. Sensor Failed" and the vehicle is not equipped with a transmission cooler, the fault code should be cleared and ignored. A software miscommunication may cause this fault to be set in vehicles without a transmission temperature sensor (No Sales Code - NHB).
If the vehicle is equipped with a Transmission Cooler (Sales Code - NHB), it will have a transmission temperature sensor and the appropriate Diagnostic Manual should be followed.
Do not attempt to install a transmission temperature sensor on vehicles not equipped with the auxiliary transmission cooler.
