I have an 07 laramie and was having 4x4 issues when the dealer told me it came up code c140d and that my transfer case shift motor needed to be replaced. Just wondering how difficult it is to switch one out and should i be looking at aftermarket or oem replacement?

 

Billy,

Found one TSB that may pertain to your problem. Thought you might want to take a look and see if it may relate to your issue. TSB below.

NUMBER: 21-011-07
GROUP: Transmission
DATE: July 4, 2007

SUBJECT:
"SERV 4WD" Lamp And DTC C1405 - Transfer Case Range Position Sensor Circuit High
OVERVIEW:
This bulletin involves diagnosis procedures to determine if the clutch apply / inner bearing
support plate is worn in the NV-246 Transfer Case (T-Case).
MODELS:
2007 (DR) Ram Truck (1500)
NOTE: This bulletin applies to four wheel drive Light Duty Ram Trucks that are
equipped with a NV-246 transfer case (sales code DH8) and were built on or
between October 30, 2006 (MDH 1030) and June 19, 2007 (MDH 0619XX).
SYMPTOM/CONDITION:
The customer may experience one or more of the following conditions:
A). Illumination of the “SERV 4WD” lamp in the instrument cluster.
B). A Malfunction Indicator Lamp (MIL) illumination due to Diagnostic Trouble Code (DTC)
C1405 - Transfer Case Range Position Sensor Circuit High.
The above condition(s) will occur when the “4WD High” mode is selected using the transfer
case mode selector switch. This condition may be due to wear on the transfer case inner
bearing support (clutch apply plate). Indentations (wear) may occur in the inner bearing
support plate surface which may allow the transfer case shift actuator to over-travel and
cause the condition(s) experienced by the customer.

 

Thanks for the info, i will definitely look into that tsb. Not sure if it applies to my issues though, my truck spit out code c140d transfer case motor circuit open. My 4wd auto light stays on all the time but truck never shifts out of 2wd no matter what position the dial is in.
