Question about 2000 Oldsmobile Bravada

Open Question

2000 olds bravada- service awd lite has been on for awhile. I recently drained and rep[laced the transfer case lubricant. Just yesterday I picked up a bad vibration about 65-70 mph.I am a retired mechanic from the 80's, so to me it feels like a driveline type vibration. Kind of rumbles in the rear, to me it feels like when a tail shaft bushing wears out, but it happend just recently. I just replaced both front hubs and bearings. could it be coming from the transfer case? I am not familiar with smart-trac.

It possible that the drive shaft need to be turn 1/2 turn and re installed, or the balance weight is missing from the drive shaft.

I can tell you exactly when my mechanic can find the part cheap enough for me to afford to replace. He's telling me its the computer sensor that automatically switches to 4WD. For now, he has taken it out so that it is in 2WD. The only thing is that the service AWD light stays on, but it works fine now even though it is only 2WD. I'll worry more about the part when it gets closer to winter. By the way, I think he said the part was $400-500 brand new. We are trying to find an after market or used one.

Has the car even been in an accident? If so it could be a bent frame (worse case), Otherwise the car could be off balance and needing an alignment (Most likely - best case) :)

Should i change the Oil in the Transfer case of my 2000 Oldsmobile Bravada AWD with 96,000 miles. I just purchased the truck ?


since you just bought the vehicle -- it is not a bad idea to do a full service on it. that way you know it has been done and from this point on you can keep up to date service records.

AWD service light io on all wheel not working


Probably a bad transfer case encoder motor. Common problem on Bravadas. Also make sure your transfer case uses only "blue" GM Auto Trac II fluid. Flush once after driving a week with "blue" if you don't find "blue" fluid when origianlly checking. Just temporarily plugging a new encoder motor to harness should get the light to go out. Other less likely problem could be bad AWD control module or fuse.

this is a verry common problem with the awd bravada a tsb was sent out telling you to change the transfer case fluid to gm tract 2 fluid well let me tell you my story first i am a mechanic of 40 + years i have a 2000 bravada awd i changed the fluid 2 times like the tsb says no fix got a low mile used transfer case instaled it put the trac 2 fluid in it no fix replaced the awd module no fix so i decided to take my old transfer case apart and see what makes it tick i found out that a spring pushes the clutch fork to disingage the front drive shaft clutches the encoder moter applys the fork sending power to the f drive shaft the spring was weak and did not disingage the cluch pack THIS IS AN EASY FIX but you should replace the fluid first if it remains the same then remove the plug in the bottom and i mean the bottom of the transfer case cant miss it it looks like a tall bolt when you remove the plug a spring will come out with it i shimed my spring about a 1/4 inch PROBLEM GONE i tested this on my old transfer case on the bench first and it worked fine i also tryed streching the old spring that did not work maybe replacing the spring with a new one might also work also i would think a new encoder motor might return to rest easer then an old one this spring is what returns the encoder motor and pushes the clutch pack to 2wd

1999 olds bravada smart trac four wheel dosent engage


Probably the transfer case encoder motor. Unplugging it at the wiring harness should make the "service awd or smart trac" light come on. This will tell you the awd controller module is probably OK. Common failure item to Bravada's. Try "thepartsladi" eBay store for lowest price motor, beware aftermarket!!! Also make sure transfer case fluid is "blue" GM Auto-Trak II only! If not bllue when checking change twice after driving for a week with blue fluid.

My poor olds!!


Possibly different tires sizes or bad speed sensors combined with a bad transfer case encoder motor? Try "thepartsladi" eBay store if you have to buy the encoder motor, beware aftermarket parts on Bravada!

drain the transfer case and check for metal particles in the fluid, there also may be debris bigger than that, try the fluid change in any event then if that doesn't do the trick you will have to overhaul the transfer case, this is a standard transfer case used by light duty trucks and SUV's based on a truck chassis, not the viscious drive type used bt passenger cars like Suburu
