I got a 2000 Oldsmobile Bravda and has smart track that works when it wants to the service light comes on once and awhile. When I really need 4wd it doesn't kick in Help


There are three different transfer case's ! Which of these does your olds have ?

Transfer Case - NVG 136-NP4 (One Speed Automatic)
Transfer Case - NVG 233-NP1 (Two Speed Selectable)
Transfer Case - NVG 236 (Two Speed Automatic)

All three have an electronic control module ! When the light is on DTC'S are stored in the transfer case shift control module .

SERVICE indicator (AWD/4WD) lamp
The SERVICE indicator (AWD/4WD) lamp is an integral part of the instrument cluster and cannot be serviced separately. This lamp is used to inform the driver of the vehicle of malfunctions within the automatic transfer case (ATC) system. The SERVICE indicator (AWD/4WD) lamp is controlled by the transfer case shift control module via a Class 2 serial data message.

There are three speed sensors on the Automatic Transfer Case (ATC), two on the rear output shaft and one on the front output shaft. Each speed sensor is a Permanent Magnet (PM) generator. The PM generator produces a pulsing AC voltage. The AC voltage level and number of pulses increases as speed increases.
Vehicle Speed Sensor
One of the two speed sensors on the rear output shaft is the vehicle speed sensor (VSS). It is an input to the vehicle control module (VCM). The VCM sends this information to the transfer case shift control module via the Class 2 Serial Data bus.
Rear Propshaft Speed Sensor
The transfer case shift control module converts the pulsating AC voltage from the rear propshaft speed sensor to a Rear Propshaft Speed in RPMs to be used for calculations. The Rear Propshaft Speed can be displayed with a scan tool.
Front Propshaft Speed Sensor
The transfer case shift control module converts the pulsating AC voltage from the front propshaft speed sensor to Front Propshaft Speed in RPM to be used for calculations, and to monitor the difference between the front and rear propshaft sensor speed. It is also used in the AUTO 4WD mode of operation to determine the amount of slip and the percent of torque to apply to the front axle. The Front Propshaft Speed can be displayed with a scan tool.

Transfer Case Encoder Motor
The transfer case encoder motor is a permanent magnet D.C. motor and gear reduction assembly. The encoder motor is controlled with a Pulse Width Modulated (PWM) signal provided by the transfer case shift control module. 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 to shift the transfer case. This circuit consists of a power supply relay (Motor Feed A circuit ) that supplies voltage to the motor. The Motor Control B circuit is a PWM driver that varies the duty cycle to control the amount of current through the motor to ground.

There are a number of codes that can set .
DTC C0300 Rear Speed Sensor Malfunction
DTC C0305 Front Speed Sensor Malfunction
DTC C0308 Motor A/B Circuit Low
DTC C0309 Motor A/B Circuit High
DTC C0310 Motor A/B Circuit Open
DTC C0315 Motor Ground Circuit Open
DTC C0374 General System Malfunction
DTC C0376 Front/Rear Shaft Speed Mismatch
DTC C0550 ECU Malfunction
DTC C0611 VIN Information Error

You don't want to just start replacing parts , that could cost $$$$$$ . You could check connections at all the sensors an the control module , but other then that ,well . Your best bet , take it to a qualified repair shop .

When accelerating hard, the rear end shake bad soon I remove my foot form the gas it stop. If I accelerate slowly no problems. Any ideas what could be the problem. Thanks


You haven't said what make and model of car it is.

On a rear wheel drive car a worn universal joint in the driveshaft (propshaft) can cause the symptoms you describe. It's sometimes referred to as a 'yoke'.

Wear causes the universal joint/propshaft to be out of line/balance and causes the vibration when the car is moving. Another symptom is a 'clunk' when the car engages gear. That clunk noise is also caused by wear.

You can check it quite easily. get underneath the car, grip the propshaft and try and turn it clockwise/anti clockwise. If there's any movement - it's worn.

Steps to removing a transmission from a GMC ENVOY 2004 V6, 4WD.


Park the vehicle in a clean dry well lit place. Work with safety in mind. Its always good to take pictures as you strip the/ a assembly. Refer back to pictures if you get stuck. Dis-connect the battery. Remove the gear linkages and speedo-drive and power cables from the gearbox. Remove the starter motor. Loosen the propshaft. Mark the yokes of the propshaft- for upon installation to avoid an unbalanced propshaft. Loosen the centre bearing. Remove the propshaft. Remove the cross member underneath the gearbox if there is one. Loosen bolts around the gearbox to cylinder block. Use a gearbox jack to support the gearbox. Take the bolts out from the gearbox to cylinder block. Pull gearbox backwards. Lower the gearbox. This is pretty much the standard way of removing gearbox. Note, there might be a transfer box, normally with 2 propshafts. Mark the yokes. Remove propshafts, transfer box and then gearbox. Remember to always work safe.

Can a 98 jeep grand cherokee 4.0l perminant 4+4 run without the front propshaft


The front propshaft on my full time 4 wheel drive 94 Grand Cherokee was vibrating badly years ago so I removed it and my Jeep has driven just fine without it since, no vibrations.Doesn't seem to cause any harm that I know of.

Loud noise when put into drive


If it is one big clunk then it might just be the universal joint that connects the drive shaft to the rear end. It is very dangerous to drive a vehicle with bad U-joints. If they break the whole drive shaft falls out. If the front u joint breaks it can act like a pole vault for your vehicle.

Gear cases are easy to take apart with the proper tools.I suggest buying a Clymer Manuel. it has a list of special tools. TEAR DOWN PROCEDURE(1) remove the propeller shaft bearing carrier assembly by removing the carrier ring. takes a special tool. (2)the bearing carrier depending on the running condition will become stuck in the gear case. there is a special tool for removing the bearing carrier out of the gear case.(3) the bearing carrier houses the reverse gear make sure the reverse gear was removed when the bearing carrier came out. (4)look inside of gear case you will see the propshaft assembly, drive shaft with pinion gear assembly, and the forward gear.(5) on the drive shaft pinion gear you will see a nut. there is a close clearance between that nut and the clutch dog on the propshaft assembly. it takes a special wrench to get this nut off plus a spline tool to hold the drive shaft as your turning the nut off. you can make them both but be careful.(6) there are two different styles for this model of stern drive a "R" and a "MR" the "MR" drive has a retaining nut for bearing preload for the drive shaft. need special tool to remove it. the "R" drive has a spring loaded pin on the top of the driveshaft to control bearing preload. no special tool need to remove shaft after pinion nut removal.(7) once the driveshaft is removed the propshaft comes out by lining up the shift shaft just right. (8) turn the shift shaft until the shift crank is at a right angle to the propeller shaft. you can't see the shift crank because it is behind the forward gear you have to go by experience or feel. once you have the shift crank lined up properly push the propshaft to the left side of the gear case housing then pull out at that angle. GOAL propshaft "clutch dog actuating shaft" in basic terms, is like a hook that grabs onto the shift crank. you unhook it by moving the propshaft tip to the side, causing the back of the propshaft inside the housing, to unhook and move away the the shift crank. it sounds complicated but once you do it you see how easy it is.(9) once you have the propshaft and the forward gear out you can leave the shift shaft inside.there is no need to remove it. have fun

Propshaft noise


Propeller (or driveshaft) will transmit noise check the joints at both ends for binding or rust (best done with it out of the car)

Do not know how or what to remove to get the propshaft off our 20


There is a "roller" or "Punch" pin through the front differential end of the splined yoke that is easy to remove.

Once located, use a round punch tool (a phillips head screwdriver will do in a jam) and a hammer to bang it though and on out the opposite side. The shaft will now slide off the spline on the differential and provide the freedom to pull it the opposite way and then slide it off the motor shaft spline.
