What’s the best way to turn a transfer case?
However, the notch is pointing straight down (6 o’clock position) and I need to get to around 11 o’clock. I can turn it to about 9 o’clock, but as soon as I take the vice grip off it snaps back to 6 o’clock. I can’t get it to go past 9, even turning the rear driveshaft.
What was the service 4WD warning code on my Tahoe Z71?
I got the Service 4WD warning on my ’05 Tahoe Z71. No lights on the selector. Couldn’t get out of 2HI. Had the code read at AAMCO, was C0327. Researching online pointed to the encoder motor sensor.
When I went to put the encoder motor with the new sensor back on, the notch on the shaft didn’t match up with the gear on the motor (which I had marked with a Sharpie, and was where it was when I took it off).
How does the transfer case work in a car?
When the vehicle experiences a rear wheel slip condition, the transfer case shift control module sends a pulse width modulated (PWM) signal to an electronic motor, which is the transfer case encoder motor. This motor rotates the transfer case control actuator lever shaft, applying a clutch pack.
Where is the transfer case motor / encoder located?
Transfer Case Motor/Encoder The transfer case Motor/Encoder consists of a permanent magnet (PM) DC motor and gear reduction assembly. It is located on the left hand side (drivers side) of the transfer case. When activated it turns the sector shaft of the transfer case (clockwise or counter clockwise) to shift the transfer case.
How does transfer case work in 4WD mode?
During the Auto 4WD mode, the power flow is the same as it is in the 4 HI mode. Except, during the Auto 4WD mode, the encoder motor rotates the control actuator shaft lever to the learned adapt ready positions. Rotating the control actuator to the various positions changes the clutch torque level.
Where is the transfer case shift encoder motor?
The 4WD Transfer Case Shift Encoder motor is the part that turns the gear inside the transfer case, allowing your vehicle to be switched into 4×4 mode. The Shift Encoder Motor is located on the outside of the transfer case and is secured to the transfer case with 3 bolts.
How does transfer case switch to 4 wheel drive?
In order for the transfer case to switch into four wheel drive, 4×4 mode a gear must be turned inside the transfer case. The 4WD Transfer Case Shift Encoder motor is the part that turns the gear inside the transfer case, allowing your vehicle to be switched into 4×4 mode.
When to use the transfer case motor lock?
Transfer Case Motor Lock. The transfer case motor lock is used to provide a 2H, 4H, and 4L lock-up feature. When the lock circuit is energized, the transfer case encoder motor is allowed to turn. When the transfer case is placed 2H, 4H, or 4L the motor lock circuit is de-energized and the lock is applied.
Do you have to shift automatic transmission manually?
I have to shift automatic transmission manually,,? fluid is good,we changed fluid and filter,still the same problem, My car has 285000 miles. My car has an automatic transmission. You may have a bad shift governor in the back of the transmission. The governor will shift the transmission as you speed up.
Where is the notch on the shift shaft?
The notch on the shaft is currently pointing straight down. The notch on the gear is more like at 11 o’clock. It was suggested to me to put the trans in neutral and jack up the rear tires.
Is there a bad shift governor in a transmission?
You may have a bad shift governor in the back of the transmission. The governor will shift the transmission as you speed up. Some transmissions have a manual type and others use an electronic type.

Is there a way to turn the drive shaft?
Right now the truck is up on ramps with no drive shaft and no encoder motor. This is my daily driver. Please help so I can get back on the road. I found this video on youtube. The guy was cruising along on this repair (without taking off the driveshaft) then at the 7:30 mark a black screen goes on saying they ran into a problem. Same problem I had.
In order for the transfer case to switch into four wheel drive, 4×4 mode a gear must be turned inside the transfer case. The 4WD Transfer Case Shift Encoder motor is the part that turns the gear inside the transfer case, allowing your vehicle to be switched into 4×4 mode.
What is mode control on GM transfer case?
The dash buttons to the right of the air vent identify this system as an NVG 246 automatic two-speed, which means it has DTCs and scan tool capabilities. mode control is a set of normally open switches that vary the voltage supplied by the transfer case module when closed.

Can a bad transmission be a transfer case?
The transfer case is a part of your vehicle’s drivetrain, as is the transmission—and they both have their respective functions. Despite this, the symptoms of transmission failure can mimic those of a bad transfer case. This can sometimes result in confusion for vehicle owners who are attempting to fix their car themselves.
What should I do if my transfer case won’t move?
You could try a relearn. If I remember the dial will rotate to the right past 4lo. hold it there for 30 seconds or so and you will hear the transfer case cycle through all positions. It’s a long shot, but worth a try. The motor is usually the problem. If you could get the code the case is setting it would help.
Is the transfer case encoder motor needs to be replaced?
From buying research to owner support, join 1.5 MILLION GM Truck Enthusiasts every month who use GM-Trucks.com as a daily part of their ownership experience. I am sure many of you read my previous post regarding the 4WD problems I am having. The dealer tells me the encoder motor needs to be replaced.
Why is oil coming out of my transfer case?
Your indication of oil coming from the motor is likely an indication of seal failure in the motor. There is a link on this site to wiring diagrams that with a VOM you could quickly rule out the switch. At 335K miles and a 99 the motor is likely the culprit, but $120 would be worth getting the diagrams and validating the switch…
Why is oil leaking from transfer case motor?
Background: had to swap out torque converter and when I unplugged bottom 2 wire connector on transfer case shift motor oil poured out. Hasn’t worked since. The fuses are good.
How does a 4 wheel drive transfer case work?
It is powered by the transmission output shaft and operates much like a secondary transmission. Most 4WD transfer cases have four modes of operation: two-high, neutral, four-low, and four-high. Because the driver only engages the 4WD when needed, this type of system is called “part-time” four-wheel drive.
What causes a problem with a transfer case?
One of the most typical problems with a transfer case is failure to engage. When this occurs it can indicate a problem with the transfer case. It can also be caused by a few other things.
However, the notch is pointing straight down (6 o’clock position) and I need to get to around 11 o’clock. I can turn it to about 9 o’clock, but as soon as I take the vice grip off it snaps back to 6 o’clock. I can’t get it to go past 9, even turning the rear driveshaft.
Why is my transfer case switch not working?
The most common cause is the transfer case switch, which is an electric motor mounted on the transfer case. To correct the issue, inspect the wiring to the transfer case switch motor for damage, and replace the shift motor if needed.
What should I do if my transfer case motor failed?
To correct the issue, inspect the wiring to the transfer case switch motor for damage, and replace the shift motor if needed. Disconnecting power to the shift motor will lock the transfer case in its current setting. The average cost for a Dodge Ram 1500 General Diagnosis is between $88 -$111.
When to replace transfer case shift control switch?
You also have to diagnose the connector of the transfer case shift control switch and the ground circuit for ground. If the TCCM fails the self-test but all these circuits turn out fine, you have to replace the TCCM. It is normal to have this message sometimes. It goes away when you shut the vehicle off and then turn it back on.
How does the transfer case control module work?
As you already know, the TCCM controls the shifting in the 4WD system. But, how does it do that? The module determines the processing of the shift by using the speed of the vehicle and the real-time transfer case mode. if the shift is possible, the TCCM will complete it by activating the transfer case encoder motor.
