I have had a recurring, nagging transmission problem with my 97 Catera. Every couple of months, after a long drive (say 1.5 to 2 hours), the {!} light would come on. If I slowed down and tried to accelerate after the light came on, it would crawl until I pulled off (only after the Check Engine light also came on). Once I pulled off and immediately restarted the car, the light would be gone. If the light stayed on, it'd trip the Check Engine light, which would stay on after restart but eventually go off too. The car never did it on short trips (say less than 1 hour) and didn't do it on every trip (every month or 2).

One of the codes that tripped indicated the possibility of low transmission fluid, and given my car has 98k miles (most highway), I my 1997 Catera to the stealership to get the transmission serviced. (I forgot the code # and can't find the printout, but it also said something about it might be a torque coverter slip.) When they dropped the transmission pan to change the filter they found a bushing in the pan. The bushing is about 2" across. It has 3 prongs on one side and is flat on the other. It is hard and brittle, but I am aware a 10 year old rubber bushing might do that. I posted 2 pictures on my Flickr.com account under coach_sck:

I also posted them in a Yahoo group photo album:

...and tried attaching them to this post.

The stealership said it'd run me $1k minimum there. I haven't taken it to another transmission shop yet (just got the car back).

2 questions:
1) Does anyone have any idea what the bushing is or where it came from? I am curious if the bushing may have come from elsewhere or a non-vital area, not necessitating a new/rebuilt transmission (which the shop will try to sell me if I take it there).
2) Would this bushing cause the above problems, or is my transmission on the way out regardless?

If it does need a transmission regardless, I am going to hunt down a salvaged one and just have it with me to save time and a diagnostic fee.

Thanks!

I figured out that the piece is the 'transmission thrust washer.' Does anyone know what it does and if a busted one necessitates a rebuilt/replaced transmission?

You will have to take the trans apart and fix this, the thrust washer takes up the clearence between the various internal assemblies. It has a specific thickness. You can get a a complete overhaul kit for this trans for about $160. another altenative is to see if GM has what is called a SRTA (service replacement trans assembly) for this, it comes with a 36/50 warranty, Delco or Jasper may also build these units. Do this before a used unit, especially if you are keeping the car, it's worth the extra expense. Just my .02.

I would mention that there is a valve body kit that fixes the cutloose problem from 2-3 or 3-2 and should probably be installed.
