#22 of 31 Oldsmobile 2001 aurora no overdrive by akfisher

I recently purchased a 01 Aurora with about 160000 miles on it, (3.5) I was driving home yesterday on the highway and stopped to make a turn and when I went to accelerate again, it would not shift into overdrive. No other problems, no clunking sounds and runs great except no overdrive. Any ideas what that could be?

I HAVE A 95 AURORA WITH 167000 MILES AND TODAY THE CAR JUST STAYS IN SECOND GEAR. IT IS THROWING A CHECK ENGINE LIGHT AND I'M WONDERING IF THIS IS SOMETHING MECHANICAL OR ELECTRICAL. HAS ANYBODY ELSE HAD THIS PROBLEM? I REALLY DON'T WANT TO PUT ANYMORE MONEY INTO THIS CAR, BUT IF IT CAN BE A SIMPLE FIX THEN I WOULD BE WILLING TO DUMP TH MONEY INTO THIS CAR...

#25 of 31 01 Aurora not Shifting into Overdrive by dmcomber

4.0 Service light came on. the codes are Po741 ( Torque converter clutch circuit stuck off) and Specific power train trouble code P1860 ( mfg TCC PWN Solenoid electrical fault) was told must pull transmission as this solenoid is in interior of transmission cost 1 to $2,000. Car seems to work fine can"t tell any differences in shifting or performance. Any ideas or sugestions?

I have an 01 Aurora with 77k on it. It recently has started to make a winding noise around 50-65 mph (real noticeable when I leave off the gas). Just had it in the shop and spent over 1100.00 on it. Was told that this could be a possible tranny problem. Are you aware of this type of issue? If so, does this require a rebuild or new tranny to fix it?
Thanks

Note it has been four years since you posted your problem and hope I can be of some help. Like yourself have a 2001 Olds Aurora with 3.5 engine. Have exactly same problem as you described; occassional hard shifts, check engine light coming on with transmission codes, occassional whine from transmission.
 
Had input output sensor replaced under warranty with no success. However mechanic at private service station I deal with advised that there is a technical service bulletin out on this problem. Apparantly it is caused by a faulty electrical connector going into transmission that creates a false signal and causes problem. This is a large, gray connector is located on the right side of the transmission (as you are looking at it from front of car). To alleviate the problem I simply wiggle the connector. Typically check engine light goes out immediately or maybe after several start-stop cycles and transmission works just fine. When in for service have mechanic check codes and inevitably come back as transmission codes, though I cannot tell you which ones.
 
Problem is getting worse as time goes on. Now have 123K on car. Big problem I face is getting through emissions testing. Have to have check engine light off and car go through several start-stop cycles after resetting light. Was able to get through in August and have almost two years before need retesting. However thought of having to spend $700 on a non-repair to pass emissions (and stay registered) is not comforting one.
 
Have you had any success with resolving problem?

I have had the same problem my boyfriend says it's because we need another motor mount because one is missing gone or idk. But I have had my "black box" for lack of actual name diagnosed and read not just the diagnostic codes but the gm one that actually basically has a convo with the computer and I had an internal mode switch failure which is in the transmission I could go on in detail of what that switch does but I believe from my reading numerous factual information on the ims that my rough shift is being caused by that it's located inside the transmission just spoke to boyfriend he agrees that I'm most likely right does the rough shift happen all the time or just some of the time after the car has had time to warm up. My 01 v6 Aurora had a rebuilt transmission put in about 4 years ago a few months after we purchased the vehicle thank God we had a year warranty also the rack and pinion went twice the air injection system is also a problem the thing I don't know actual name of the part but it's located behind the front driver side wheel well behind the plastic splash protector is bad gm acknowledged the problem and made another one and another place to mount it at being that if water gets in that "which I've gone through 4 secondary air injectors before I started looking up other failure problems" your air injectors are shot or singular but just thought I'd throw that info in here too I wish I remembered the actual name of it but I'm on my cell so not able to look it up without this being deleted. But I'm sure if u have an 01 Aurora you have an air injection problem too almost all do his many miles ya got I just hit 111111 lol took a pic at 100000 and that not very often u get to see that let me know if you have gotten your trouble codes do you have a vented battery and if not any problems with electrical and do you still have the stock Radio

I had the same problem and it turned out to be a relatively inexpensive fix. It was a solenoid that was causing the problem... the parts were like 130 and the labor was about 120.

Not much new to report on my original problem, as it does reappear now and then (several times per year), generating an audible whine to go along with the jolting shifts. At 191K now I won't do anything costly to address it. I stop the car and turn off the engine, and then re-start after a minute or two, and the problem disappears. It's like there's a blockage on an intake that gets stirred up once in a while causing a starvation problem that affects shifting. Shut it off and the blockage falls away. Or so it seems. I note that the fuel economy is adversly affected too, when it is acting up. The posts referenceing a torque converter solenoid problem really sound like they are on the right track.
