ONe other thing. As the prior poster recommended. I would have the tranney oil changed out again by a trustworthy/knowlegeable person. Look for metal shavings as expressed by the prior poster. Also verify that the filter was put back into place.
 
Replacement fluid should be GM grade transmission fluid , nothing more and nothing less.
 
When you drain from the pan your only replacing 6-7 quarts of the fluid. You do not actually change out all of the tranney fluid when changing from the pan.
 
Verify your gasget at the pan to see that it is not cracked. you said you have it dripping around the pan. This is not a good sign. You could have been running the car with low transmission fluid levels. A new GM gasget for this car is 50-75$ unless you go with the cheap cork aftermarket gasget which I only reccommend if you plan on keeping the car for a couple years.
 
Draining and checking the tranney fluid is your cheapest route to take. If you go the alternate route of replacing the tranney (mind you if this is the problem) your cost will go up considerably.

I have seen this before. May be a differnt problem. If you lift the rubber housing right next to the steering column and the light blinker handle. pull this back. If you look inside there are contacters that the handle touches. Did you try squirting some contact cleaner into that area on the contacters and then turn your light switch back and forth to clean those areas up. Poof my lights started to work again.
 
in some instances those contacters become shorted and your lights will turn on even after the iginition has been shut off. Have seen many peoples batterys drained becasue of this same issue.

Thank you for your response! I have a question now about the tranny fluid since you say GM grade should be replacement nothing more & nothing less.... when the altenator was changed and I went to Kragen Auto Parts to get the Anti-freeze and Tranny fluid the gentleman gave me some tranny fluid that was labeled MD3... I told him the year make & model of my car and he said that would work. Ever heard of it?? I am use to putting Mecron/DexronIII in any vehicle Ive owned now I'm wondering if this is the cause of the problem... Wow, I would really hope not. You all are great here, your input truly helps and I definitely appreciate it.

Thanx for the response, and all the information.... I am printing this out for my referrence. She is being towed to the Tranny shop for the diagnostic shortly (waiting for the tow guy now). I do not want to chance messing with it until I hear what they find. I forgot to mention previously that when I went to the autopart store to get the anti-freeze and the tranny fluid the gentleman gave me MD3... Ever heard of it? I told him the year make & model of my car and he said it would work. Im use to Mercron/Dexron III but took his word because he was the salesman. I hope this didn't lead to the problem.
As for the swap, Im thinking of just buying the other Aurora he wants $450 for it now. The guy says it needs a new engine, it has a bad rod knock. It only has 118k on it, and I believe it's well worth more than $450.
I will keep you posted on my tranny issue... Hope it's something simple.Thanks again for all your help!

MD3 or mercon/dexron III are for most cars/light truck auto. transmissions built between 1980 and 2005. 2005 and newer GM's not so much.
 
Again, I would drain and verify that there are not shavings or metalics in your oil or attached to the magnetic strip just inside the pan. your best hope is that you had air pockets in the modulator
 
Good luck.

There was a change in fluids around 1998 to part synthetic. It was these newer fluids that would cause clutch deterioration in older vehicles. Ford and GM orginally stated it was a replacement for the older fluid as well but shortly learned of the clutch material deterioration, brown fluid, and changed their position. It would be hard to say if off the shelf fluid makers changed their formula to something more compatible. Rebuild transmissions need to use clutches of newer matierial so they don't break down with this newer fluid. If you did a total fluid change, retrieve a sample of the fluid from the tranny. You might have some legal recourse.
Along witht he many headaches pointed up concerning someone swapping the tranny for you, there are a couple of points about pulling a tranny from junk. If the vehicle was wrecked the impact can damage parts inside. There is a lot of weight suspended on the main shaft and it has only a bearing at each end. Also there are bearings between those heavy components, clutch packs, planetary gears, etc. and the main shaft. So, in addition to the possibilities of the main shaft being bent just enough to through it out of balance, there is the possibility of these soft material bearings being dimpled by the impact. They actually are more of a bushing made of material like the connecting rod bearings and depend mostly on the thin layer of oil to stop damage.
Ford had a bulletin concerning damage because people failed to use the parking brake. Any incline would put the torque of the wheels into any of the final drive components, that is all solid connections between the wheel and the parking pawl in the transmission. The result was that every last drop of lubricant was being forced from points of bearings resulting in dry starts. Dry starts are very bad and the beginning of wear points that will deteriorate faster than other areas. The bulletin specifically addressed transmissions, but with a little thought you will see this also affects the CV joints on the drive shafts. I'd say it is very important to always use the parking brake.
Other than a few of us that found the bulletin on the net, I'm unaware of this info being passed to customers.

Thank you for the information. I am going to drain all the fluid in about an hour or so and check for metal shavings etc. If this doesn't resolve the problem I will be taking her to a transmission only shop and let them do a diag on her. If the transmission is no good, then away she goes . Again thank you for all the information, and I will be sure to let you know what becomes of her.

Drained the fluid from the tranny, found a very small amount of shavings and I mean very small almost looked like dirt. The gasket looks brand new (and it should had the torque converter & solenoid replaced July 07) filters were not clogged, fluid was actually red and not brown as I thought. Going to replace the fluid now, and see what happens. Thanks again for the input.

Well... I tried draining the tranny, going through all the steps as advised and to no avail the problem still exists. I am starting to think it may be the speed sensor "again". I say again because after reading the invoice from the torque converter replacement I noticed a lot of other things. Of course it had a 6 month or 6000 mile warranty and I am well past both. I am going to list what is on the invoice because I would really like to know if it is common for any of these parts to fail within a 14 month period...
1 Torque Converter $265
1 EDC Solenoid $97
1 filter $45
1 filter left $15
1 filter rt $21
1 input speed sensor $45
1 solenoid PWM $65
fluid supplement (block) $20
12 quarts ATF Fluid $42
 
Here are the codes that were listed as well...
90- v cc brake switch input prob.
95- engine stalled
95- shift ratio "A" problem
109 - Internal ECM problem
27- Throttle switch or circuit open
39- torque converter clutch malfunction
56 - input speed circuit problem
52 - defective ecm
70 - intermittent throttle position.
 
All these things were listed and according to the repair order fixed. The total out of pocket expense was $1697. How common or rare is it to have issues with the same parts? Im leaning toward the speed sensor because now she acts as though she wants to shift, but still doesn't. Also forgot to mention previously that I use to get a loud thump when put in reverse but since I drained fluid and replaced it has disappeared.
Would you happen to know how difficult it is to change the speed sensor? I went and purchased another, hoping to be able to resolve it this way and avoid the costly labor at the shop. I really need a manual on this car and no one seems to have one other than the dealer.
Your help is greatly appreciated! It actually keeps me from giving up on her... she is expensive, but when she is up and running wow the comfort & reliabilty is well worth the expense.
