From another site - the text below is NOT from me:
Bulletin No.: 77-71-73
A/T - Revised Serviceability of 1-2/2-3 Shift Solenoids
Date: January, 1998
Subject: Service Availability of 1-2 and 2-3 Shift Solenoids
1993 Cadillac Allante
1993-98 Cadillac Eldorado, Seville
1994-98 Cadillac Concours
1996-98 Cadillac DeVille
1997-98 Cadillac d'Elegance
1995-98 Oldsmobile Aurora
with HYDRA-MATIC 4T80-E Transaxle (RPO MH1) and with 4.0L, 4.6L Engine (VINs C, Y, 9 - RPOs L47, LD8, L37)
During the 1996 Model Year, transaxle Julian date 047, a new 1-2, 2-3 shift solenoid assembly, and a pressure control solenoid valve fluid filter retainer, were implemented on the 4T80-E transaxle.
All transaxles with a Julian date prior to 1996, 047 must be serviced with a service kit - 1-2/2-3 shift solenoid valves, which is available at GMSPO. This kit, P/N 24211355, contains the 1-2, 2-3 shift solenoid valves, the pressure control solenoid valve filter, the pressure control solenoid valve fluid filter retainer and the bolt to hold the retainer to the lower control valve body. All components in this kit must be used when servicing these transaxles.
1996 transaxles with a Julian date after 047, and 1997 through 1998 transaxles, should be serviced with individual components.
a) the job is a mess, be prepared.
b) drop the pan, and careful remove the tranny gasket, it is re-usable. Once you clean the pan, you can reset it with gasket sealer.
c) disconnect the solenoid electrical connectors and the mechanical linkage. The linkage has a metal clip you lift and slide.
d) remove the valve body screws, and drop the valve body.
e) place the valve body where you can afford a mess, it will continually leak. Best thing is to set it on cardboard on a bench. There is a valve spool that can be removed as well, careful it can slip out, you don't want to damage it.
f) remove the two clips holding the solenoids, careful they are spring-loaded and will fly
g) remove the screws holding the "large" portion of the valve body split, this is where the solenoids are encased. Remember the screw locations, there are about four different screw lengths
h) CAREFULLY remove split, there are 4 steel check balls loose inside the split (about 1/4" diameter, they will fly, as well)
i) inspect spacer plate, if the black coating is not chipping off you can re-use it, otherwise plan on spending another $ 70 at the dealership parts house. If you replace it you will have to remove the "smaller" split, as well. It also has three check balls.
j) replace the solenoids
k) now comes the fun,....you will note three holes in the spacer plate where three of the check balls reside, seat them there (appr. 3/16" diameter with a smaller relief hole next to it, as I remember). The fourth check ball will need to be inserted in a spherically-cast cavity which is near one the solenoids. You can set it with grease, I re-assembled successfully without using grease.
l) re-assemble valve body, carefully and equally torque.
m) you will note a square black plastic item near one of the solenoids, on the end. Replace this plastic filter with the new filter in the solenoid kit. The kit will also come with an L-shaped bracket that is to be used to "capture" this filter and keep it from backing out. The kit also comes with a slightly longer screw used to mount the bracket to the valve body (discard the old screw).
m) re-assemble valve body to transmission, hook up linkage and electrical connectors
n) replace both tranny filters
o) replenish fluid
p) reset codes
#2508 of 4484 Aurora will not start
Apr 24, 2005 (12:39 pm)
I have a 1995 Aurora with 150,000 miles on it. Yesterday it just stopped in the middle of the road. I cranked it many times and no start, it did not even come close most times. twice out of 40 times is started but it was ideling very slow, When I hit the gas it died. Later in the day (after the flat bed) I changed the fuel filter, the plugs and the wires. The car still just turned over. For some reason it started this am on the 10th try, ran around the block great turned on and off properly, then it started cranking again... thats where we are now. I have read about the FPR as a possibility. Could a fuel pump cause this problem? could it be a problem with the spark?

I have a 1995 Olds Aurora with a problem with the dash lights not working with the lights on. They also go off with the fog lights on. Any solutions would be appreciated.

Could be the fuel pump... Henri had his die in, what was it, the Holland Tunnel?
FPR would be long crank-crank-crank starts (especially on warm starts)... probably a good preventative maintenance change, since it's easy and fairly inexpensive...

Where is the fuel pump actually located in this vehicle ( 1995 Aurora )? Is there any way to trouble shoot the fuel pump. I have tried to locate a repair manual for this vehical but there does not seem to be one....any ideas?
Question on the long crank with a bad FPR, how long is a long crank, I never cranked more then 3 or 4 seconds.

Fuel pump is inside the fuel tank. Access is through a removeable panel in the trunk just behind the rear seat (or drop the tank). I would not have been able to replace my fuel pump without the lock nut wrench tool (Kent-Moore J-39765).
Factory service manuals are available from Helm (www.helminc.com); also try eBay.
If your FPR is leaking, there will be fuel in the flexible tube that runs from the FPR to the intake manifold. That's what causes the engine to flood and to be hard to start.

Hey, this statement reminds me:
I would not have been able to replace my fuel pump without the lock nut wrench tool (Kent-Moore J-39765)
What Aurora-specific tools have shadetree mechanics had to buy? I know about the water pump removal tool, and now this one for replacing the fuel pump. Anything else Aurora-specific that I should get? Now that Olds is gone, I have the service manuals and want to get any specific tools that I need.
My Aurora goes into storage for the summer on Friday of this week . I've been spending time detailing and prepping the car, inside and out. Still looks/shines/smells great. It'll ride great once I replace the shocks and struts in the fall (every time I hit a significant bump I can feel the car shudder sideways a little bit, so I know it's time)...
#2514 of 4484 Start up & computer issues Auora 2001

Hope you can help with this. Check engine light is on, low engine coolant keeps popping up after i took to dealership & they said nothing was wrong with it & re-set the computer. still showing check engine light & low engine coolant.
About 2 weeks ago, put 3 gals of gas in, drove to a gas station (Costco) for cheaper gas & my car tried to turn over but it took several tries before it started up. Every since then, the car has not started immediately. I never had any issues with the hardware before. It's been a great car. Now, this morning, i went to start & same thing only it made a noise like something came loose & next try, it started immediately BUT sounded like something was hitting the fan.
the last car i had the rod broke in the engine so i dont' want to start it up in case there is engine/motor damage. HELP please....
Thanks, Aurora in NC

Has anyone ever had the sunroof not close in the proper position? Mine seems like it needs to come up 3/16 or so to be flush with the roof. Is there a adjustment that can be made? Thanks.
