It is highly recommended that be changed at the same time as a tranny rebuild or replace. You might luck out or not. If when you refilled the tranny there were air pockets fluid may have slugged a modulator valve or some other component, especially if you did not let it idle long enough in gear with wheels off ground to allow the transmission to clear all the bubbles and then slowly increase RPM enough to force shifts. The downside with this is that you should have the car supported at the strut so that you are not turning CV joints at the fully extended point. Such a slugging could break a spring in a clutch pack, modulator valve, accumulator, etc. If it is in the modulator pack, it is accessible without pulling tranny from the bottom. I also suspect the end pan may be removeable if some parts are removed from the front of the engine (the belt end) and the engine/tranny assembly is slid to that end. Do check for clearance if trying and let me know if it works. But also there is a known problem with a couple of solenoids in that lower valve assembly and there is a service upgrade for that. Typically they break and leak. Usually this leaves limp home mode which gives only first and second gear and reverse. The parts for that fix were around $100 and you can probably find where several have done the work themselves in one of the Aurora forums. Biggest headache seems that some have accidentally misplaced a small part so it is imperative that you use caution in disassembly and reassembly. Make sure you have a contained environment so that if some small part drops you can find it and check the area routinely for stray parts. Other than basic tools you should have a small torque wrench, which I consider basic anyway.

That being said they are compounded when dealing with the Olds Aurora. The cost of fixing them can go through the roof. Any one who says that the Aurora is an economical car to maintain is full of something or they work for GM(mind you not for long). Brown by the way is not good if this is the color. I would question the person that put this oil in for you when you said you changed out your transmission fluid. Happy trails.

Replying to: ndeysayau95 (Dec 31, 2008 9:16 am) 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.

Replying to: jeff8789 (Oct 16, 2008 4:45 pm) 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. |

Replying to: e_net_rider (Jan 02, 2009 7:48 am) 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! |

Replying to: ndeysayau95 (Jan 02, 2009 12:34 pm) 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. |

Replying to: ndeysayau95 (Jan 05, 2009 1:59 pm) 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.
