Late this summer,the AWD disable light would display intermittently for maybe a day or two.Following the advice of previous posts,i checked all wheel sensor connections for corrosion or open circuits. All sensors were receiving a voltage signal also.The main connector under the car in the drivers seat area also checked okay.
Finally,the light came on constant. I brought it to a local GM dealership for diagnosis.The cause was a bad "rear differential clutch pump actuator check valve",which is the piece on the front of the differential with a wire harness attached.The part was $422.00, labor was $262.00 which included the diagnosis charge of $120.00 i was initially quoted.
#22 of 91 2005 Buick Rendezvous transmission prob?
Dec 21, 2010 (4:47 pm)
I have a 2005 Buick Rendezvous 6 cyl. auto. 119k that's transmission makes a clunking noise shifting into 1rst gear(only) sporadically in stop and go traffic. If I hit the gas, this doesn't not happen. Almost feels like I am driving on ice. I had the transmission fluid flushed recently, and that was normal. This doesn't happen all the time. Any clues?

Hello Everyone: (02 RDV 155,000 km to date CXL)
Its been awhile since I posted. 4.5 years ago my old RDV went through some very bad times, intake manifold, head gaskets and transmission failure (at 90,000 km which GM WOULD not help with) AC condensor for the 3rd time and radiator . Before this I had around 25 minor items repaired (wheel bearings, electrical shorts, trim falling off or cracking, chrome on wheels peeling off, just general poor quality issues)
Well over the last 4 years its just been general maintenance (O2 sensors, plugs and belts...etc). This year I had a brake line failure which was very serious. Its the front brake lines and it rusted out at the bend behind the firewall. My wife stopped the car due to a front wheel bearing failure (the whole bearing housing assembly failed and the wheel came loose). At the same time she noticed a huge puddle under the car (turned out to be brake fluid).
So please everyone have your mechanic inspect the front brake line just in behind the Master cylinder for rust and leaking. No one wants to have this fail on the HWY (dead meat). Very expensive to repair though 600 bucks with parts.
Also another expensive job just done was radiator failure (AC DELCO RAD) transmission fluid mixed with coolant (1500 bucks to fix.., but better than a cracked block as suspected by mechanic). So if you have a DELCO Rad keep an eye on your coolant for gunk mixing.
Current general maintenance, and there is a GM bulletin for this, is transmission coolant lines will leak. and mine are leaking. I regard this as general maintenance after 9 years on the road. However, alas I am looking at getting rid of my RDV to get something more reliable and not so expensive to keep on the road. This was my first GM vehicle and it looks like my last one. This one just left a bad taste in my mouth with poor quality and poor customer service. GM for this vehicle anyway will not stand by the customer. Lately they seem to be turning the corner, but its too late for me.
I will keep looking here for information and posting stuff until I rid myself of the RDV just to keep people posted on customer experience after 9 years on the road.

I had to replace the rear differential clutch pump check valve on my 06 rendzvous at 28,000 miles after the AWD disable light came on. The part cost $406.63 and the special fluid for the differential cost $37.90 per qt. Total cost was $847.90

My "AWD disabled" light is on and I suspect the check valve is bad on my 06 Uplander. I just changed the rear fluid so am not looking forward to replacing it again! Does anyone know if I can check if the valve is the problem by just plugging in a good valve(without installing in differential) and seeing if the fault goes away?

do you still have your 05 Rendezvous? Were you able to diagnose the transmission problem?? I have the same problem on my 06 Rendezvous and wonder what the result was.

Yes, we still have the Rendezvous. I took it into our mechanic, and they couldn't get it to duplicate the problem. It only happens at certain times, usually when you try to accelerate at a stop sign/light. It will go for a month, not doing it. (sporadic) I'm under the impression that it might be a solenoid? (sp) It happened again this Saturday, when accelerating out into traffic.
Have you also had problems when you hit a bump the speedometer goes out? Either stays at zero or 90! What fun on a long trip. Our mechanic says that this is an issue with this car. Either control panel or computer. We had to use our GPS to know our speed. If we shut it off for a few minutes, everything works! It has been a great car until this!

I apologize for the problems you are experiencing. Were you planning on having the vehicle diagnosed by a GM dealership? Please keep me posted when the issue has been taken care of.
